Project Information

Summary:

Adopting sustainable agricultural practices can increase complexity and management, frequently challenging farm profitability. Crop diversity, a pillar of sustainable agriculture, often relies on rotations that include less profitable crops necessary to disrupt disease and pest cycles. As society demands further strengthening and defining of sustainable practices, markets must also evolve at the same rate to keep farms in business.

To support farmer goals of sustainability and profitability, we propose research and educational outreach projects that will accelerate the development of regional markets for proso millet and buckwheat (Figure 1). These rotational crops intrigue not only Northwest farmers but also our diverse regional stakeholders; processors, maltsters, brewers, millers, bakers, chefs, and schools demand access to these crops. Our stakeholders voiced a need for variety recommendations, nutrition and malt quality data, and networking among growers and end users. We had no regionally adapted resources to share.

For two years, we’ve communicated with stakeholders to develop a project that meets their needs. These discussions gave rise to a highly skilled and motivated project team that includes farmers, food and crop scientists, Extension specialists, and market experts. Together, we successfully identified the crops of interest and identified five main objectives:

1) establish a regional baseline for production and end-use quality of millet and buckwheat varieties currently grown in Idaho and Washington by determining their flavor, food functionality, and nutritional quality to bolster marketability via appropriate end-use recommendations;

2) conduct researcher- and farmer-led millet and buckwheat field trials to identify new varieties for the region that improve upon baseline; 

3) characterize new millet and buckwheat varieties for flavor, food functionality, and nutritional and malt quality to determine end-use suitability while also developing optimized product formulations for focaccia mix, pancake mix, and children’s breakfast bar;

4) conduct a market assessment for regionally produced and processed millet and buckwheat with consumer surveys, school district questionnaires, and stakeholder interviews; and

5) use outreach, education, and networking tools to support supply chain development and product awareness among stakeholders to build consumer demand, grower interest, processing capacity, and market connections for millet and buckwheat crops and products.

To ensure crop access, familiarity, and adoption, our project uniquely engages producers and stakeholders along the entire supply chain in collaboration. We will devote much of our project resources to on-farm trialing to not only identify regional differences in variety selection but also to boost farmer confidence in the crops. Stakeholders guided our project target end uses to represent products already in production, and enthusiastically support optimizing product formulations to showcase inclusion of regionally produced millet and buckwheat in value-added products. Our educational outreach is focused on developing lasting relationships and exchanging information throughout the supply chain to support the production and processing of these crops. Our project has the potential, in the short timeframe of three years, to establish a cohort of 20 growers equipped with appropriate varieties of millet and buckwheat to satisfy the cohort of over 20 regional end-use stakeholders who have expressed a demand for the crops.

Research

Hypothesis:

1) a regional baseline for production and end-use quality of proso millet and buckwheat varieties currently grown in Idaho and Washington will determine differences in flavor, food functionality, and nutritional quality and will establish categories for appropriate end-uses;

2) researcher- and farmer-led proso millet and buckwheat field trials will determine differences in agronomic performance among varieties across the region; 

3) new proso millet and buckwheat varieties will differ in flavor, food functionality, and nutritional and malt quality. Data will determine end-use suitability and guide the development of optimized product formulations for focaccia mix, pancake mix, and children’s breakfast bar; and

4) a market assessment will determine stakeholder preferences for regionally produced and processed proso millet and buckwheat.

Materials and methods:

Objective 1: Establish a regional baseline for production and end-use quality of millet and buckwheat varieties currently grown in Idaho and Washington by determining their flavor, food functionality, and nutritional quality to bolster marketability via appropriate end-use recommendations (Year 1).

In Year 1, we will assess regional millet and buckwheat production and end-use to establish baseline information on agronomic and end-use performance and to inform improvement strategies. We will map commercial millet and buckwheat production and gather quantitative data (acreage, variety, yield, end-use). We will collect representative grain samples from commercial growers and analyze them as outlined in Objective 3. We will conduct producer interviews at the beginning and end of the project (Table 1) to document producer needs and enable evaluation and impact assessment.   

In the following research and education objectives, we will show how we will assess flavor, food functionality, and nutritional quality data to identify optimal end uses for each crop and variety grown. We will work with our producer-collaborators and stakeholders to develop reliable food processing methods to bring these crops and products to market (Figure 2) (Objective 3). For example, a producer-collaborator-grown millet crop would be preliminarily evaluated, milled, and then used in products developed with a collaborating stakeholder and Dr. Ganjyal’s lab. Expert sensory panels, consisting of research team members and stakeholder-collaborators, will be used to provide focused feedback that informs the optimization of product formulations (Objective 3). Panelists will complete a questionnaire (Table 2). Later in the project, consumer acceptability and preferences will be crowd-sourced at outreach events using rapid response surveys at booths with taste-testing activities (Table 2) (Objective 5.4).

 

Objective 2: Conduct researcher- and farmer-led millet and buckwheat field trials to identify new varieties for the region that improve upon baseline (Years 1-2).

The project aims to select new millet and buckwheat varieties that improve upon baseline agronomics, flavor, food functionality, and nutritional quality. Varieties will be assessed with a mother and baby trial (MBT) design that captures regional adaptability (Figure 3). Most commonly used in participatory plant breeding, the MBT approach links researcher-led “mother” trials, where all crop factors are evaluated in a replicated design, to farmer-led “baby” trials (not replicated on farm but replicated across farms) to capture diverse management practices and environmental conditions [21].

MBT locations (Figure 4) will span temperature and precipitation regimes in Western WA/Northern OR (buckwheat) and Eastern WA/Idaho Panhandle/Northern OR (millet). Buckwheat sites will have varied planting times as well as precipitation and temperature regimes. The buckwheat mother trial site will be located at the 78th St. Heritage Farm in Vancouver, WA, typified by a Willamette Valley regional climate with slightly higher in-season temperatures and lower precipitation than most confirmed buckwheat baby trial sites located in more maritime regions of the NW. The millet mother trial will occur at the Spillman Research Farm in Pullman, WA; the site receives 21-in. mean annual precipitation (MAP). Baby trials will be located within 260 miles of Pullman in WA, ID, and OR, with MAP ranging from 11-in to 24-in. We will identify additional baby trial hosts in cooperation with Shepherd’s Grain, a group with extensive farmer networks in the Inland Northwest.

One mother trial will be planted for each crop species (Years 1-2); a researcher-led randomized and replicated variety trial of millet in Eastern WA (7 varieties) and buckwheat in Southwest WA (6 varieties) will each. The mother trials will include varieties identified in Objective 1, lesser known commercially available varieties, and breeding populations developed in Washington state. We will determine key traits of interest for each crop with the producer interview (Table 2). During the proposal development, growers identified weed suppression, ground cover, and a short growing season as important traits for buckwheat and millet in their rotation. Evaluated traits will include percent emergence, days to canopy closure, disease incidence/severity, days to maturity, plant height, and yield.

A sub-set of varieties will be grown across a range of environments in non-replicated, farmer-led, on-farm baby trials (Years 1-2; 1-4 varieties, plus a control variety) per crop to determine variety performance across environments and capture farmers’ perceptions and acceptance of new varieties. The control variety will be replicated at each baby trial. The host farmer will determine the size of a baby trial and the number of entries at each trial. Replication of varieties across farms will increase statistical power for assessing variety differences across locations. We will analyze data among baby trials if more than three growers are assigned more than one of the same variety or if growers elect to replicate within their farms. We will encourage participating farmers to plant field-scale experimental plots (> 0.25 acres) to effectively assess variety performance in their system. Large plot sizes will capture the heterogeneity across a field, which helps improve inference when replication is otherwise lacking. Host farmers will provide qualitative data (e.g., vigor, overall acceptance, production challenges) and quantitative data (e.g., emergence, canopy development, yield).

By using both replicated trials (“mother”) and non-replicated trials (“baby”), the MBT experimental design allows flexibility in analysis when using a mixed-effects model. We can: (1) determine the correlation between variety performance on-farm (baby trial) and variety performance on-station (mother trial); (2) measure variety reliability using the probability it will perform above or below the mean; and (3) conduct pairwise comparisons of varieties. If a variety is not replicated across farms and is therefore not well represented across the region, fewer inferences can be made [22]. However, these data remain critical to the project because they inform future variety selection decisions by farmers. Additionally, the qualitative data provided by farmers will be included in our publications, with permission.

Seed produced in MBTs will be used to develop product formulations and for nutritional quality and food functionality assessments (Objective 3). The remaining baby trial seed will be incorporated into products by stakeholder collaborators, used for bird seed by Global Harvest Foods (Spokane, WA), and used for on-farm livestock feed.

 

Objective 3: Characterize new millet and buckwheat varieties for flavor, food functionality, and nutritional and malt quality to determine end-use suitability while also developing optimized product formulations for focaccia mix, pancake mix, and children’s breakfast bar (Years 1-3).

Dr. Murphy’s lab will perform nutritional characterization of millet and buckwheat samples from MBTs. Mineral content will be measured with traditional analytical methods. Data will be used to develop calibrations for high-throughput analysis via near-infrared and x-ray fluorescence spectroscopy. An innovative flatbed scanner phenotyping platform will measure seed size, shape, color, and thousand seed weight.   

Physicochemical properties of flours are important for identifying how the flours perform in different food applications. The chemical compositions and functionalities of millet and buckwheat from breeding trials in Objectives 1 and 2 will be measured in Dr. Ganjyal’s laboratory. The chemical compositions to be evaluated include starch, protein, fiber, crude fat, and ash content. These will be determined using standard methods. Flour functional properties to be evaluated include thermal, pasting (rheological), and hydration properties[23,24]. A Differential Scanning Calorimeter will perform thermal analyses. Pasting properties will be analyzed with a Micro-Visco amylograph[24]. The water absorption index and water solubility index will be measured according to published standard methods[23]. All data from the above physicochemical analyses will be used to categorize the millet and buckwheat varieties for processing conditions and potential end-use applications (food and malting/brewing). (Figure 2). Using this approach, Dr. Murphy and Dr. Ganjyal have successfully categorized diverse varieties of quinoa into groups based on the most appropriate end use, such as noodles, pasta, sauces, soups, and different baking products, depending on physicochemical analyses[23].

We will select millet and buckwheat varieties based on their chemical composition and functionalities to develop three food product formulations: focaccia mix, pancake mix, and children’s breakfast bar. Formulations will be optimized to maintain or improve flavor, texture, and nutritional quality. WSU Malt Quality Lab (Pullman, WA) will provide consultation and support malting, malt quality analysis, and interpretation of malt quality with sensory data provided through stakeholder-expert panels.

The varieties of millet and buckwheat will be selected and tested in the following specific food applications: a) focaccia mix, b) pancake mix, and c) children’s breakfast bar.

Focaccia mix – Focaccia mix formulations will be tested. Wheat flour + millet flour blends (0, 25, 50, 75, and 100%), as well as wheat flour + buckwheat flour blends (0,25,50,75,100%) will be used as the base formulation for the focaccia mix. A commercial wheat-based focaccia will be used as control.

Pancake mix – The product formulation will be initiated from a commercial pancake mix. The wheat + buckwheat flour blends (0, 25, 50, 75, and 100%) and the wheat + millet flour blends (0, 12.5, 25, 50, and 100%) will be evaluated and compared with the 100% wheat pancake mix as controls. 

Children’s breakfast bar – The product formulation will be initiated from a commercial breakfast bar, and up to 40% of buckwheat and millet blend will be used in the formulations. Formulations will be optimized to have millet and buckwheat as leading ingredients and to maintain taste and texture without compromising nutritional value

An expert sensory panel and the research team will evaluate select products from each of the above-mentioned categories for consumer acceptability (Figure 2). The expert sensory panel will include stakeholders who already carry the identified three products, are interested in branching out into those products, or produce other products (e.g., noodles, beer) but will provide informative feedback on the varieties tested. Our stakeholder-collaborators will also use the products as the initial formulations in development of commercial products. For example, a buckwheat variety identified as a high performing flour in quick bread mixes will be 1) sourced from a baby trial (Hidden River Farm); 2) dehulled, kept as whole groats, or milled; and 3) shipped to a stakeholder-collaborator (Snacktivist). Snacktivist will use the buckwheat in the pancake formulation provided by the research team but will also be encouraged to experiment beyond the provided formulation (Figure 3). Snacktivist will complete a questionnaire (Table 2) designed to provide the research team critical information on end-use suitability of the variety and performance of the product formulation. Several of our stakeholder letters of support identify additional members on the expert sensory panel.

 

Objective 4: Conduct a market assessment for regionally produced and processed millet and buckwheat with consumer surveys, school district questionnaires, and stakeholder interviews.

We will work with WSU’s Division of Governmental Studies and Services (DGSS) to assess marketability for millet and buckwheat products. Over the three-year project period, we will: 1) conduct consumer surveys; 2) provide school districts comprehensive questionnaires; and 3) interview stakeholders to better understand pricing and feasibility of product incorporation (Table 2).

Because the majority of consumer groups relative to our project are not easily reached via random sampling, nonprobability methodology (convenience sampling) will be used. The increased response numbers obtained through nonprobability survey methods will provide important information regarding the local market for these products while avoiding the substantial costs of probability surveys. The survey will be promoted among partners such as the Culinary Breeding Network and Organic Seed Alliance and will take advantage of mailing lists, other listservs, newsletters, social media, and websites. The targeted audience will also be reached via our Field to Flavor Showcase events.

School districts are a key institutional buyer. We will develop a comprehensive questionnaire to capture school district requirements such as price ranges, sourcing constraints, product fit, food safety certifications, volumes handled, and volume periodicity. We will email a link to a web-based survey to all 294 school districts in Washington State and to school districts in Idaho and Oregon familiar with farm-to-school projects.

We will conduct a series of in-person interviews with businesses/stakeholders (including those on the expert sensory panel), to gain a better understanding of the potential they see for the grain varieties they tested, feasibility of incorporating millet/buckwheat into their products, and to assist in guiding price estimation. The target audience for this outreach will be largely informed by responses to the surveys conducted earlier in the study. Survey data will be entered, cleaned, and analyzed by the Division of Governmental Studies and Services, as will data obtained through the interviews.

Research results and discussion:

Year 2 Progress (preliminary results)

Buckwheat mother trials

Field trials were implemented at the proposed trial site in Vancouver, WA in both 2022 and 2023. Both trials were largely implemented as described in the original proposal, with a replicated experimental design using large 640 sq. ft. individual plots (80’ x 8’) to evaluate six varieties of commercially available buckwheat in a western Pacific Northwest (PNW) environment. In 2022, the trials were planted on June 8th and harvested in Late September into early October. In 2023, the trials were planted on June 16th (ongoing). In 2022, buckwheat followed a cover crop of crimson clover that was mowed and incorporated into the soil the third week of May, and was estimated to be able to supply ~60 lbs/ac plant-available N, in-season. In 2023, the same N fertility protocol was used but the crimson clover winter-killed, so 26 lbs/ac of fertilizer N was added along with 30 lbs/ac of K, 13 lbs/ac of S, and 5 lbs/ac of Fe. Data has been collected on yield (total biomass, stand height, and seed), stand counts, progression of crop emergence and flowering, and canopy cover from two 10.76 sq. ft. (1 square meter) subplot sampling areas within each plot. Sub-plot sampling areas were each located ~27 ft inward from each end of a given plot area lengthwise, and positioned centrally ~2.5 ft inward from the plot edges width-wise. For yield, three additional subplots were hand-harvested from each plot in addition to the two main subplots to assure that that buckwheat quantities were ample enough to supply the needs of the processing trial team. All hand-harvested grain samples were threshed and cleaned using a mechanized plot-scale thresher. The trial used a standard field-scale grain drill (8 ft width with 7-in spacing between openers) for buckwheat seeding (at 50 lbs. seed/acre) and a standard field-scale combine (with a 10 ft header) for harvest after subplots were hand-harvested. This allowed us to additionally gather insight into buckwheat production with regard to using equipment much more comparable to the grower’s experience with this crop (vs. hand-sown/harvested or typical small-scale plot research equipment). All buckwheat that was bulk-harvested with the combine was dried (targeting ~12-13% moisture) and cleaned with a two-screen air screen cleaner, and then supplied to the processing research team. All data from 2022 has been collected, although results have not yet been analyzed. Data collection for the 2023 trials is ongoing.

Buckwheat field trials were coordinated in western Washington and Oregon at ten farms in 2022 and seven farms in 2023. In 2022, each farm grew on average three varieties, which included the control (Mancan) at each farm. Each variety on average was grown in four locations. Plots for each variety were typically ¼ to 1 acre, though one site (The Evergreen State College Organic Farm) grew plots on only 15-foot x 4-foot prepared beds for student instructional and research purposes.

Buckwheat baby trials

In 2023, farmer-participant buckwheat trials were conducted on seven farms, with an average of four varieties per farm, with each variety grown on average at four locations. Mancan again served as the control and was grown at every location.

Results from farmer trials included the following: 1) an emergence observation (data not yet analyzed), 2) a mid-season plant vigor evaluation (data not yet analyzed), 3) an end-of-season interview, 4) yield data from 1m2 x 1m2 sub-samples across all farms and sites, and 5) buckwheat rate trial examining average (55 lbs live seed per acre) and high (100 lbs live seed per acre) seeding rate treatments. Specific management recommendations were provided to growers regarding seeding date, water management (based on seeding date), fertility, seeding rate and depth, and harvest practices. Based on researcher observations and grower input from end-of-season interviews, the following results and observations were obtained:

Overall performance was directly related to stand establishment and vigor

  • Buckwheat did very poorly, but it was external conditions. Farmer has grown lots of buckwheat in the past that did just fine. Germ was good and so was early growth. His soil was damaged by being plowed too early, which messed with the soil structure, then it was really hot and dry and he didn’t water it.
  • Competition with weeds was an issues, Lambs Quarter especially. Weather was also an issue, and lack of water
  • Did not suppress weeds if not vigorous
  • Performance was variable, decent overall, best in lowland
  • The buckwheat suppressed weeds, but only when it could grow vigorously, had a tough time competing with the wild mustard
  • Weeds grew where it didn’t germinate well, the timing was difficult, and this farmer couldn’t get the buckwheat to dry down
  • It did suppress weeds, and worked even better when interplanted with the birdsfood trefoil
  • Buckwheat suppresses weeds sort of, especially when grown with favas
  • Looked good, not excellent. Especially for seeding late around June 15th or so.
  • Buckwheat suppressed weeds well: Yes, pretty much. Think it did. Wasn’t too dirty. Had some shade.
  • It finds enough moisture to grow unirrigated, provides good shade cover for the soil, and is excellent habitat for pollinators
  • No weed pressure, very few weeds germinating by the time he plants, the weed pressure is mostly from winter grasses; no major challenges, OG certified so can’t spray and has some weeds. Does a lot of pre-plant cultivation. Cultivated 3 times before he planted using a finish disk.

Farmers liked the flexibility of the grain, and found ways to experiment with it

  • Nice that it could be planted late, but stayed too wet, low input is nice likes that it is not necessary to cultivate the buckwheat
  • It was easy to grow, a good green manure to rejuvenate soil, it grew well with birdsfood trefoil
  • Buckwheat is versatile and equals pancakes
  • Interested in yield data, uses it as a summer cover crop along with fava beans. Plants it early in spring where mid-season crops will go.

Harvesting buckwheat is an impediment

  • Harvest was difficult, adjusting the combine correctly was hard, the seed was too fluffy, he had to have the fan speed on the combine turned down
  • Timing is difficulty, and this farmer couldn’t get the buckwheat to dry down
  • Was supposed to sell it but he couldn’t separate out the weed seeds with his combine so it was unsellable (for this reason has no future market objectives for growing buckwheat)
  • Can’t plant it thickly enough to be profitable, when he planted it thickly it lodged and he couldn’t pick it back up with his combine (and this grower has a pick-up combine, the only one with)
  • Harvested a little for household use (made pancakes!), and used as food for geese and ducks
  • Big seed, looked healthy, good stem, held up good. We were just too late. Would have liked to be able to swatch and pick-up combine, but don’t have pick-up header. Was vigorous, didn’t lodge.
  • Got a bag, fed it to the ducks through the winter. The combine bogged down, didn’t have a pick-up header so couldn’t harvest it all. Standing in the field, burnt some of it the other day. Too thick of a stem for the combine to harvest.
  • Sells to Ukrainian and Russian population, would sell to that. But didn’t get enough. Was too damp even at harvest. Would have molded. Ropey. Would need to swath it and then use a pick-up header. Swath and dry, hope for 7-8d good dry weather. Bill’s perspective is its so moist around here is hard to dry. Humidity he thinks is a problem. To be consistent.

        Identifying a market in advance will be critical

  • He might like to grow as bedding hay in the future
  • The crop was not harvested, it was worked back into the soil
  • Has grown buckwheat for Patagonia in the past, they wanted to make noodles with it but they didn’t. They are very interested tho. Has grown 10 acres for customers/production in the past. He only wants to grow buckwheat as a cover crop unless he can make more money per pound selling it as a specialty item. He had someone come teach him and his crew how to make buckwheat soba noodles
  • Wants to plant a larger trial if possible. He would be interested in any culinary varieties that he could sell for a higher price. Would be interested in a Russian culinary variety

Locking in best management practices in advance is critical for such a short-season crop

  • Should have watered but ran out of time/didn’t
  • Even in unideal conditions for grain, very useful as a summer cover crop, but pay attention to changing conditions
  • He hadn’t planned on watering but he did so it would germinate. It was planted so late.
  • Plant it somewhere where it can access moisture
  • Water was his biggest issue, all the rest was pretty equal
  • Will plant earlier, water it, and use manure or fertilizer
  • Use fertilizer, don’t overpack when you plant it, water it, if lodging is a concern, plant thinner and use less fertilizer
  • Planted on 6/16, normally plants a month earlier. Put the buckwheat in ground that had been worked early and didn’t plant spring cover on it. Did stale seed bed before planting and didn’t have an issue with weeds
  • Reed canary grass was its biggest competitor, and not watering it was an issue. This farmer claims the crop needs to be irrigated. Also had trouble planting earlier in the season because of weather.
  • [Researcher observation relevant to many farmer comments]: Spring 2022 was cold and wet early, and then dried out fairly rapidly, delaying seeding while also making growth difficult past germination
  • Buckwheat won’t take frost, even the most minor frost will be bad
  • No, he did not/does not water buckwheat when he grows it (despite late planting date) (Hedlin, 6/16 planting)
  • Got planting depth right, his planting grew well, he planted in fertile soil that had been fertilized to grow vegetables

Variety performance varied and did not produce an obvious preference

  • Overall germination was good
  • No “worse” variety
  • Horizon was the most variable, Kitawase did the best, it was competitive with the weeds and didn’t lodge (Hidden River)
  • Koma was the worst, it lodged and was hard to harvest but it did smother the weeds
  • Mancan performed (Fagerness). It sprouted almost as fast as Horizon, had more mass (he’s using it as a green manure), and didn’t lodge (none of his varieties lodged)
  • WSU variety as not as good, maybe yield was the same but he thought it looked more yellow. Also the WSU variety didn’t have the mass and yield that the other varieties had (Fagerness)
  • All went well, good emergence, Kitawase was faster (Hedlin)
  • None lodged and either Koma or Kitawase was 6-8 inches taller than the others; All came up, all were goo.
  • Could grow commercially with a little higher ground. Koma was the best, WSU had a hard time coming up. #3 going from house to road 1-3, with #3 on far side of driveway/gravel road. Was a nice even stand, come up even, could be varying by other factors, but just seemed to do best.
  • He like Mancan the best. WSU Pop and Mancan looked the most lush to him. WSU Pop was not as good (the 2nd planting he put in was better). He had no clear favorite, but he liked the ones that were denser/more lush as he was growing it for ground cover

Farmers are interested in specialty markets

  • Trying to expand grains/dry goods market. Will sell packaged grains at Farmers Markets, Webstore, CSA and hopefully SWWA Food Hub

Producers had remaining questions

  • Is there a difference between indeterminate varieties and determinate varieties?
  • Is the indeterminate v determinate a factor in what varieties to grow for culinary purposes?
  • Performance of different varieties. Interested in ones that are early, or if there are flavor differences among varieties. Also interest in yield data

Producers had observations

  • Buckwheat contamination with wheat/other crops has not been a problem, it’s usually in full bloom when he turns it in, but that anything that regrows is killed by frost. He says he has no issues with buckwheat contamination
  • Study up on how they grow it in other places. Find a market for it first. It is easy to grow but hard to sell for a profit
  • Make sure can get it in early enough. Grow on a sufficiently dry site.
  • Put on some cow manure and chicken manure on this ground. Even if don’t put down, grow on the better ground. Definitely need to swath it. If the summer was really hot, might be able to combine it standing up. If the stem was under 15% moisture he thinks could possibly combine it. Get it on flat, level, not shaded ground, a southern elevation (more heat).

Seeding rate trials completed on a subset of project varieties (Koto, WSU, Komo, and Mancan) at the WSU Puyallup Research and Extension center in summer 2023 demonstrated that both variety and seeding rate significantly influence buckwheat cover at an important time frame while weeds are competing with the crop during canopy closure. Average stand cover under the high rate was 90.6% while stand cover under low rate was 70.8%. Regarding variety effect, only Mancan showed significantly lower plant cover (61.3%) than the other varieties (Koto: 88.8%; WSU: 87.3%; and Komo: 85.5%), suggesting significantly greater stand vigor for all test varieties compared to the control.

Buckwheat market assessment

Market assessment was supported by a survey conducted in collaboration with the Washington State Office of Superintendent of Public Instruction (OSPI), and the WSU Division of Governmental Studies and Services (DGSS). A survey was developed by the WSU research team with OSPI, reviewed by DGSS, and determined not to be Human Subjects research by Washington State University. The survey was sent to all 295 school districts in Washington State, and queried respondents on interest in utilizing products made and processed from millet and buckwheat products grown in Washington State, among other topics. A data sharing agreement was developed for OSPI to share survey results with the WSU research team. The agreement is under review by contracts offices at OSPI and WSU, and data will be available by the end of summer 2023.

 

Market assessment was also supported by an event evaluation completed following a July 2023 “Field to Flavor Showcase” event for members of the Washington School Nutrition Association. This evaluation provided direct feedback from WSNA members regarding opportunities to integrate Washington-grown millet and buckwheat products into school meal programs.

I have a lot of knowledge of farm to table in the hospital/restaurant setting & being a gardener/produced for a restaurant - salad greens, radishes, snap peas. Have a lot of understanding of roadblocks & can help give more ideas of what might be more practical to work towards for future

Buckwheat pancakes

Loved taste testing recipes! They were all delicious!

More education in the school of what I have always wanted to do  but now feel it's easier to do.

It's very educational!

Buckwheat "crepes" made in a sheet pan with poached fruit inside from another member!

Great event!

Using vegetables when they are most available

I enjoyed all of this event. Thank you!

Ways to implement buckwheat and millet into our program.

This was a great pre-conference tour. Well put together and presented. Thank you!

Loved this - so cool!

 

Millet Variety Trials and On-farm Evaluations

  • Mother Trial
    • A proso millet “mother trial” was planted at Spillman Agronomy Farm in Pullman on May 22, 2022. Seven varieties (Earlybird, Dawn, Horizon, Huntsman, Plateau, Sunrise, and Sunup) were planted in a replicated complete block design.
    • In-season data collection included rate of emergence, days to heading, days to maturity, plant height, and emergence.
    • Plots were harvested between September 1 and September 15, 2022.
    • Seed samples from each plot were cleaned and dehulled to prepare for analysis of seed morphology and nutrition (in progress).
  • On-farm Trials
    • Five growers across the inland Pacific Northwest planted proso millet “baby trials” in 2022. Each grower was assigned between three and seven varieties to plant in unreplicated strips on their farms using full-scale planting equipment. Growers planted and managed their crops, but researchers collected samples from each plot to compare plant height and yield of test varieties.
    • Interviews were conducted with each grower before planting and after harvest in order to understand grower management decisions and overall experience working with the crop.

 Food Science (preliminary outcomes)

  • Received six proso-millet varieties. All six were planted in the same controlled location, and several varieties were planted on various farms across the PNW. We analyzed 28 samples for their functional properties and proximate composition.
  • Received buckwheat varieties. All six were planted in the same controlled location, and several varieties were planted in two farms across the PNW. We analyzed 14 samples for their functional properties and proximate composition.
  • Performed a study on the influence of the proximate and physicochemical properties of dehulled and whole buckwheat flour on focaccia bread quality.
  • Performed a study on the proximate and physicochemical properties of alternative grains (proso-millet, buckwheat, wholewheat, and quinoa) and their influence on pancake quality.

Research Outcomes

Recommendations for sustainable agricultural production and future research:

Preliminary research outcomes for buckwheat production

  • Buckwheat can be grown with or without irrigation in Western Washington, but growers need to take into account seeding date, weather/seasonal water availability (in soil and projected from precipitation), soil type, and availability of irrigation water to manage for a successful buckwheat crop. Some additional information on interactions between these factors, with quantified cut-off thresholds, would be helpful.
  • Integrating legumes into buckwheat production can be used to boost weed suppression, increase nitrogen fixation, provide additional nectary resources, and improve soil cover. Farmers in this trial experimented with Birdsfoot trefoil and fava beans.
  • Utilizing low ground (subirrigated), proper planting date, or irrigation, is essential to plant stand and thereby weed suppression by buckwheat
  • Growers should consider increasing seeding rate from 55 lbs/ac to as much as 100 lbs/ac for sites with high weed pressure, or other factor that may inhibit canopy closure.
  • Selecting a variety other than Mancan will increase canopy closure and increase effectiveness of buckwheat as a weed-suppressing crop
  • Growers need to ensure adequate moisture either through sub-irrigation, earlier seeding date, or irrigation to ensure crop vigor and potential both for weed suppression and high yield

Education and outreach methods and analyses:

Year 1.

In mid-March, a project newsletter was sent to producers who agreed to host on-farm variety trials of buckwheat or proso millet (n = 21). The newsletter included links to relevant reference materials, a schedule of important upcoming activities, a summary of successful project benchmarks, and a team directory with contact information and roles of each researcher. Future monthly newsletters will maintain communication with the group of producer collaborators. The newsletters complement direct communications with producer collaborators during the project.

The newsletter included information for on-farm trial management (e.g., field preparation, planting, chemical inputs, and harvest practices). Guidance was informed by Extension documents from other universities. The team clearly disclosed that the information provided to producers was summarized from research not specific to our region; producers were instructed to use best judgement in tailoring practices to their local conditions. Producer experiences during the upcoming field trial seasons will inform two management guides (one for proso millet and one for buckwheat) that will be published as part of this project.

A webpage for the project was developed and added to the Sustainable Seed Systems Lab website (https://www.sustainableseedsystems.org/new-grains-nw.html). The webpage uses a new name for the project, New Grains Northwest, which was developed during several project branding sessions. The webpage provides an overview of the project, project photos, project rationale, project team and stakeholder information, baseline data, and field trial information. Interested stakeholders are frequently directed to the webpage.

Our first research station field day for the proso millet mother trial and a buckwheat test plot will occur on July 7, 2022, at the Spillman Research Farm in Pullman, WA as part of the Inland Northwest Artisan Grains Conference.

Year 2.

Buckwheat Outreach and Supply Chain Development

Supply chain development has so far been supported through a) collaboration with Washington State school meals programs and b) industry/culinary partners.

(a) Regarding school meal partners, the WSU/OSPI survey, and WSNA evaluations demonstrate interest in utilizing products made from Washington-grown millet and buckwheat. Key barriers to supply chain development are confirmed markets, which could be the schools themselves, and a private partner capable of and interested in development products that utilize millet and buckwheat.

The school survey will provide preliminary data regarding school interest in millet and buckwheat products, which may provide a sufficient market to develop a product line of dry bread mixes (focaccia and pancakes) and a breakfast bar. To address private partner for product line development, the outreach team has explored Clif Bar, Patagonia Inc., and Cascade Milling. Neither Clif nor Patagonia have expressed interest beyond initial involvement as stakeholders in the project.

Cascade Mill out of Royal City, WA is a company that mills organic grains for a variety of wholesale markets through Washington State and the Pacific Northwest. Preliminary discussions with Cascade Mill suggest interest, as the company is already mixing a line of pancake mix that they intend to market to school meal programs. Added nutritional value, and additional farm and University partnership, are compelling fo the company and meetings have been occurring in July and August 2023. A partnership would potentially include shipping Washington grown buckwheat to Cascade Mill this fall for pilot mix development. To make economic sense, Cascade Mill representative Patrick Boss notes that “…the volume would need to be at least about 1 full truckload (about 42,000 lbs. of product) once every two months or once a quarter.” To determine if this demand exits, the research team will follow up with school meal partners who have expressed interest in participating in the pilot through the WSU/OSPI survey, and the WSNA pre-conference tour.

Opportunity to utilize farm-to-school grant funding was identified in spring 2023 through meetings with WSDA Farm-to-School program coordinator Annette Slonim, and OSPI Farm-to-School coordinator Nichole Garden. Programs that could help support purchase of Washington-grown grains for school meal programs include the following:

  1. WSDA Farm-to-School Purchasing Grant program (https://agr.wa.gov/departments/business-and-marketing-support/farm-to-school-toolkit/grants), the current round of which opened August 2023 and closes September 25th, 2023
  2. The OSPI Commodity Food Purchasing grant program, that subsidizes procurement of W-code foods to offset use of potentially more expensive WA-sourced ingredients in processed foods (such as pasta sauce, or products envisioned by this program: focaccia bread, pancake mix, or breakfast bar)
  3. OSPI Local Food for Washington Schools program, which provides funding for sourcing specific products for school meal programs such as bison, salmon, frozen processed vegetables, or potentially one of the products developed for this program)

(b) Regarding industry connections for millet and buckwheat supply chain development, several local partners and small and larger scales are interested in utilizing millet and buckwheat in specialty manufacturing and for value-added farm sales. These include:

  • Farms such as Kirsop Farm that have an interest in direct sales of buckwheat groats at farmers markets
  • Hedlin Farm which is interested in culinary varieties that could sell for a higher price premium
  • Ghostfish Brewing company which could utilize Washington-grown grain for malting
  • Malting companies such as Linc Malt, which has opportunity to market Washington-grown malted buckwheat
  • Snacktivist, a specialty foods manufacturer who is interested in Washington-grown millet and buckwheat varieties if they were available as groats or flour
  • Restaurant partners including Elise Landry at Chicory Restaurant in Olympia, WA, and Katchka Restaurant chef Bonnie Morales, who utilized buckwheat on her menu until the Ukraine-Russia conflict, and she could no longer source the grain reliably
  • Soba noodle makers in Portland, OR and elsewhere who need a stable supply of buckwheat flour if it could be sourced from Washington farms
  • Milling and baking companies such as small-scale breadmaker and miller Ryan at Baker-Potter, who would like to source buckwheat groats from Washington for milling but has no supply; and Cairnspring Mill owner Kevin Morse

 

Education and outreach results:

Buckwheat and Millet Education and Outreach

Buckwheat and millet education and outreach tables were included in the 2022 Sagre del Radicchio (https://www.chicoryweek.com/events/2022/8/30/radsagra). Photos of the event are available on the project website (https://www.sustainableseedsystems.org/new-grains-nw.html).

Three education and outreach events occurred or are scheduled for 2023, including the WSNA pre-conference tour held July 2023 for members of the Washington School Nutrition Association, a “Buckwheat Fest” scheduled for August 28th in Chimacum, WA (https://seedalliance.org/events/buckwheat-festival/), and a WSU Extension/Culinary Breeding Network “Field to Flavor Showcase” in Vancouver, WA.

Summer 2023 a “Field to Flavor Showcase” event was organized as a pre-confernence tour for members of the Washington School Nutrition Association. Members were taken on farm tours, a tour of buckwheat research plots, and served novel dishes featuring buckwheat. Recipe formulations from the WSU Food Science program for pancakes and focaccia bread were utilized. Evaluation feedback provided direct data from 27 WSNA members, who are employed as lead chefs and food service directors at Washington State K-12 schools (evaluation results noted below in Outcomes).

Education and Outreach Outcomes

Recommendations for education and outreach:

Among the 27 attendees of the WSNA pre-conference tour, 90% (n=22 respondents) increased knowledge of culinary uses of millet and buckwheat, 86% increased knowledge of opportunities for including millet or buckwheat products in school meal programs, 86% learned how crop rotations (such as those that include millet and buckwheat) improve the sustainability of agriculture, and 83 percent increased knowledge of crop seasonality to support purchasing directly from farms. Among those, an average of 79% plan to utilize their knowledge, with some respondents noting their limited capacity to implement change as they are not food service directors but rather line cooks or head chefs.
