My proposed solution is to build full hybrid corn seed production capacity on my farm so organic and non-GMO farmers in the southern states finally have access to seed that is bred, produced, and conditioned in an environment similar to their own. The lack of regionally adapted hybrids has held back organic corn production for years, especially in water-limited systems like ours. Producing hybrid seed locally, using genetics developed specifically for our climate, is the most direct and practical way to solve this problem. I have licensed two Texas A&M AgriLife hybrids-TAMZ106 and TAMZ107-and my goal is to establish a reliable system for producing their parent lines and hybrid seed on my organic acreage. These hybrids were bred in the Texas High Plains, and they bring the traits farmers in our region need: early maturity, heat and drought tolerance, insect resilience, and strong yield potential under limited irrigation. Producing these hybrids here at home will give organic farmers access to seed suited for our soils, water limitations, and climate.

To accomplish this, I will create a complete seed production system built on parent-line increase, well-designed field layouts for hybrid production, isolation, flowering synchronization, detasseling or pollen-control operations, specialized harvest techniques, seed conditioning, quality testing, and secure storage. This system is different from grain production. It demands precision, especially in protecting genetic purity, removing off-types, and coordinating flowering between male and female rows. I already manage certified organic acreage suited for hybrid production and have experience producing organic grain and seed, but hybrid production requires additional training and equipment.

My collaboration with Dr. Wenwei Xu and Bob Whitney provides the technical support needed to make this solution achievable. Dr. Xu, who bred the hybrids and parent lines, will guide our field layout decisions, isolation requirements, flowering synchrony, and detasseling steps. His team will train my staff to recognize tassel emergence stages, manage male and female rows, and maintain purity throughout the production cycle. Bob Whitney will help us integrate hybrid seed production with organic fertility management, weed control strategies, and soil conservation practices. He will also support our outreach efforts so that other farmers can learn from this project.

Throughout the project, I will build the knowledge and systems required to produce high-quality hybrid seed year after year. To do this, we will track measurable indicators indicating whether the system works and whether the seed we produce is dependable for farmers. These measurements include acres planted for parent-line increase, the amount of seed harvested from each parent line, hybrid seed yield per acre, seed purity, germination rates, and the potential number of acres that could be planted using the hybrid seed we produce. These metrics will help us evaluate how well the hybrid production system performs under organic and water-limited conditions, and whether it can be scaled up to supply farmers across the region. By collecting these data over two growing seasons, we will gain a clear picture of what hybrid seed production requires in our environment and long-term sustainability of the model.

The final pillar of the solution is acquiring the specialized equipment needed for hybrid seed production. Producing hybrid seed requires tools beyond typical production. I need equipment for handling small lots of parent-line seed, cleaning and sizing hybrid seed, and conditioning seed. I also need better drying and storage systems to protect seed quality. These investments are significant and would be difficult for a family-owned operation to take on without support. The SARE grant will allow me to purchase equipment and build the foundation needed for a sustainable hybrid seed enterprise.

This proposed solution leads to more sustainable outcomes in several ways. First, producing regionally adapted hybrids improves water-use efficiency. These Texas A&M AgriLife hybrids were bred for drought and heat tolerance, which means they convert limited irrigation into biomass or grain more efficiently than hybrids bred in wetter climates. Because organic farmers rely heavily on irrigation from the Ogallala Aquifer, better-adapted hybrids help conserve water and reduce stress on the aquifer. This contributes to long-term environmental sustainability for agriculture in our region.

Second, this solution improves profitability for organic farmers. When hybrids are better suited to a farmer's environment, yield becomes more stable, stalk strength improves, and the risk of crop loss decreases. Organic farmers cannot rely on conventional fertilizers or pesticides to rescue a struggling crop, so having hybrids with stronger stress tolerance is essential. By producing seed locally, we can supply farmers with genetics that perform consistently under the heat, drought, and pest pressures common in the southern states. Better yields and improved forage quality strengthen farm profitability.

Third, producing hybrid seed in our region supports rural economies. Right now, nearly all hybrid seed-even non-GMO seed-comes from the Midwest. Building regional capacity keeps seed dollars in our community and creates new opportunities for agricultural labor. This strengthens the long-term stability of rural farming communities in the southern Plains.

This solution will strengthen resilience in organic cropping systems. Hybrids that emerge well, tolerate stress, and maintain strong stalks reduce the need for rescue tillage, repeated cultivation, or other high-energy interventions. This lowers fuel use, reduces soil disturbance, and builds healthier soils. Early maturity also benefits organic dairy operations, which rely on predictable silage harvest schedules to maintain consistent feed supplies.

Finally, this project supports public breeding programs by creating a pathway for Texas A&M AgriLife genetics to reach organic farmers who need them. These hybrids were developed for the southern region, but without regional seed production, farmers cannot benefit from them. By building capacity on my farm, we open the door for future regionally adapted hybrid seed development and regional seed independence.

This proposed solution is specific, measurable, achievable, and realistic. It builds on the land, experience, and partnerships I already have, and adds the equipment and training needed to produce hybrid seed for organic farmers across the southern states. With this project, we will establish a sustainable seed-production system that continues long after the grant period, contributing to the sustainability of agriculture in our region.

My project will take place on my certified organic fields in Lubbock and Hale Counties, where I will establish parent-line seed increases and hybrid seed production of the TAMZ106B and TAMZ107 hybrids. These fields represent the same semi-arid, limited-irrigation environment where organic farmers in the southern states grow corn, making them an ideal site to demonstrate how regionally adapted hybrids perform under real production conditions. I will use pivot-irrigated fields that meet organic certification requirements, and I will separate isolation blocks from commercial corn fields by more than 700 feet, exceeding the distance typically required by the seed industry. I will also use staggered planting dates if needed to provide additional temporal isolation and ensure seed purity.

The project begins by obtaining breeder and foundation seed of the parent lines for TAMZ106B and TAMZ107 from Dr. Wenwei Xu, who developed these hybrids through the Texas A&M AgriLife Corn Breeding Program. These hybrids share a common parent line, which simplifies the production system and allows both hybrids to be produced efficiently. I will plant each parent line in its own block to increase the amount of parent seed available for hybrid production. During parent-line increase, I will measure stand establishment, flowering time, plant vigor, disease pressure, and overall seed yield. These measurements will help determine the best field layout and planting schedule for larger-scale hybrid seed production.

Once enough parent-line seed are available, I will establish hybrid seed production blocks using distance isolation. I will plant male and female rows in alternating groups, using planting patterns recommended by Dr. Xu. Because the parent lines have similar maturity and synchronized flowering when planted on the same day, I will not need complex split-planting schedules. I will monitor growth stages daily to ensure that tassels on the female plants are removed before they shed pollen. This detasseling process ensures that all seed harvested from the female rows will result from cross-pollination by the designated male rows, producing true hybrid seed. I will track labor hours required for detasseling, tassel emergence timing, pollen shed dates, and silking dates. These records will help refine the production system and determine the feasibility of expanding hybrid seed production in future years.

During hybrid production, I will measure traits that matter to organic farmers and seed customers. These include stand counts, uniformity, flowering synchrony, plant height, ear height, lodging, disease pressure, and insect pressure. I will also monitor irrigation applied, rainfall received, and field operations performed. At harvest, I will collect hybrid seed from the female rows and self-pollinated parent-line seed from the male rows. Seed will be dried, cleaned, and conditioned using the specialized equipment purchased through this project. I will evaluate seed purity, seed size, physical quality, and germination. Samples of parent-line and hybrid seed will be tested to confirm that the production system remains clean and meets non-GMO requirements.

The second part of the project focuses on testing the performance of the hybrids on organic farms. I will work with two additional certified organic farmers to conduct strip trials of TAMZ106B, TAMZ107, and a commercial non-GMO hybrid currently used in the region. Each trial will include three replications, with strips at least 100 feet long and four rows wide. We will use commercial planters to establish these strips so that results reflect real production conditions. Data will be collected from the center two rows to avoid border effects.

Across the three organic farms, I will record stand establishment, early vigor, flowering dates, plant and ear height, green snap, foliar diseases, insect injury, and any stress responses observed during the season. Yield will be collected either as grain or chopped silage depending on the goals of each cooperating farmer. For silage trials, I will measure biomass yield, dry matter, and moisture at harvest. For grain trials, I will record total grain weight, test weight, harvest moisture, and lodging. These measurements will allow us to directly compare regionally adapted Texas A&M hybrids with the most commonly used non-GMO hybrid in organic systems.

To support data analysis, I will maintain detailed records for all fields involved in the project. This will include soil test results, fertilizer inputs, compost applications, irrigation schedules, rainfall, planting dates, and harvest dates. I will use GPS markings to identify locations of parent-line blocks, hybrid production blocks, and strip-trial plots. Data will be summarized using simple spreadsheet tools to compare performance across sites and treatments. I will calculate average yields, stand differences, flowering intervals, and plant health indicators for each hybrid. Data from parent-line increase and hybrid seed production will help determine how many acres of seed can be produced annually, how much purity can be maintained, and how production practices affect seed quality.

Interpretation of results will focus on determining whether the Texas A&M hybrids can be reliably produced on organic farms in the southern states and whether the hybrid production protocols can be scaled for commercial seed supply. I will evaluate whether flowering synchrony, detasseling efficiency, and distance isolation provide adequate genetic purity. I will examine whether seed yields and germination meet commercial standards. For the strip trials, I will compare yield and plant performance to understand whether TAMZ106B and TAMZ107 offer advantages over widely available non-GMO hybrids. Results will be interpreted with input from Dr. Xu and Bob Whitney, who will help identify which agronomic traits are most important for organic farmers in the region.

The methods used in this project directly address the problem organic farmers face. By increasing parent-line seed, producing hybrid seed under organic management, and testing hybrids on real organic farms, we will generate practical information and build the capacity needed to deliver regionally adapted seed to farmers. These methods measure exactly what farmers care about: yield, vigor, stress tolerance, purity, and seed quality. At the same time, the data will show whether hybrid seed production is feasible for my operation in the long term and whether these hybrids can help organic farmers achieve higher yield stability and better water-use efficiency.
