Project Information

Summary:

Historically, the Delmarva (Delaware-Maryland-Virginia) Peninsula was a major hub for strawberry and raspberry production. However, current commercial production is negligible on the Eastern Shore (Somerset-Wicomico-Worcester) of MD. Similar situations exist in Delaware and Virginia. The cultivation of June bearing (JB) strawberries using the traditional matted row system is the only source of farm income during the spring season and thereafter most of the produce is imported from distant states. Similarly, growers in these areas are heavily depended on floricane fruiting type raspberries (FFTR) that too on small acreage. The cultivation of FFTR requires two year for fruit production and consume time and resources for pruning and disease management. In fact, cultivation of both the berries is negligible on the Eastern Shore with no information available on raspberry acreage in 2017 USDA Census of Agriculture. Most of the local growers have no idea about the existence of day neutral strawberries (DNS) and primocane-fruiting type raspberry (PFTR) varieties, which can extends the harvest season. This proposed extension outreach work will demonstrate sustainable approaches to extend the growing season using multiple JB and DNS under low and high tunnels and open bed regimes. Similarly, our sustainable approach to complement the existing FFTR cultivation system by PFTR under high tunnels regimes will accelerate the local berry production with more profit at farm. Our extensive extension plan (multiple hands-on training) will initiate the rejuvenation of strawberry and raspberry cultivation on the Eastern Shore of MD to benefit socially disadvantaged farmers, women farmers, small farmers, veteran farmers, and BIPOC (black indigenous and people of color) growers. The advisory board of this extension program is highly diverse, comprises extension agents, local growers, veteran farmers, BIPOC organizations, consumers, and faculty members to incorporate holistic education, and subsequently reaches to farmers from all the strata of the farming community.   

Performance Target:

10 Agriculture service providers who enrich their knowledge of season extension in strawberry and raspberry crops will teach 25 farmers about the use of June bearers and day-neutral strawberries and primocane raspberries for season extension in association with low and high tunnels. 10 Agricultural Service Providers will provide individual consultation and advice to 20  interested growers. 10 Agriculture service providers will further disseminate the work by the publication of factsheets and online study materials to 45 farmers and host workshops using the University of Maryland Eastern Shore (UMES) Small Fruit Plots for 45 farmers.

Introduction:

Description of Problem or Opportunity

Strawberries are economically important and a consumer favorite in the USA with a total production of 2.6 billion pounds (lb) in 2020 (USDA-NASS, 2021). In spite of increasing domestic demand, local production in several eastern states declined and almost nonexistent in local areas (Rom et al., 2014). Earlier (1919) USDA-NASS Census of Agriculture showed the existence of 5,260 strawberry farms and 7,000 acres with strawberry cultivation in Maryland (MD), which is now restricted to 146 farms and 210 acres (USDA-NASS, 2017). These data show a decline in strawberry acreage by 97% within a century. We are expecting further declines in strawberry production on the Delmarva Peninsula due to inclement weather throughout the growing season of JB and day neutral cultivars (DNC).

Currently, there is little production out of the main April-June period; therefore, season extension is essential for strawberry market and profit at farm. The strawberry industry in Mid-Atlantic is chiefly dominated by JB, short day cultivars, which restrict the peak production to spring or early summer seasons only, thereafter the primary supply is maintained by import from California (Mar.-Nov.) and Florida (Dec.-Feb.).

Similarly, raspberries (Rubus idaeus L.) are an economically important crop in the USA. Raspberries are also grown in the NE USA and Mid-Atlantics, but this production is not sufficient to fulfil the local demand. Raspberry production is negligible in the Tri-county area (Wicomico, Somerset, and Worcester) on the Eastern Shore of Maryland (USDA, NASS, 2017). There are only 4-small farms in Wicomico and Worcester County, which occupy a total area of less than 1 acre with raspberry cultivation (USDA, NASS, 2017).

Raspberry is a temperate crop, bears perennial roots, and short lived woody shoots called ‘canes’ (Sonsteby and Heide, 2008). These short-lived canes are of two types; biennial floricanes and annual primocanes. However, in floricane raspberries, the plants survive for two seasons and require labor-intensive pruning and protection from chilling temperatures (Pritts, 2008). Primocane-fruiting raspberries can extend the season from late summer into fall while floricanes harvest is restricted to six weeks during summer (Pritts, 2008). Moreover, annual removal of primocanes can limit the annual cycle of pests and pathogens, thus decrease expenses for fungicides and insecticides.

In 2020, under COVID-19 situation, I established an online coalition of growers and consumers with 181 active members throughout the Delmarva Peninsula to deliver online SARE workshops. An online request was communicated with coalition members to provide inputs on strawberry/raspberry cultivation challenges faced by them and to be the part of the advisory committee to develop the current extension outreach proposal.  15 farmers provided following challenges and knowledge gaps, which are  incorporated in this proposal. In addition, our previous work on strawberry crop also showed some of these indigenous challenges. A: Source of strawberry and primocane raspberries, B: How to make raised beds? C: How to grow DNS? D: How to construct inexpensive low tunnels, E: Strawberry varieties suitable for Delmarva Peninsula, F: Technique for high tunnel production of strawberries and raspberries, G: Common pest and pathogen management.

 Proposed Solution: 

Even though strawberry industry is declining on the Delmarva Peninsula (USDA-NASS, 2017), there is no comprehensive extension outreach work was done on the production potential of multiple JB and DNC in open bed (OB) and high and low tunnel (HT/LT) regimes. A new system of strawberry cultivation, plasticulture system has showed improvement in yield and fruit quality compared to the matted row system (Fiola et al., 1995). Introduction of the HT system has been shown to advance the growing season of JB with early and high yield. HT protects the crop from low temperatures during the fall, early spring frosts, and as a consequence generates more revenue at the farm level (Rowley, 2010). We will demonstrate season advancement using the JB and HT/LT combination. To further extend the strawberry season beyond summer, we will demonstrate the cultivation of suitable DNC, which are insensitive to day length and have multiple harvests throughout the season (Lewers et al., 2017). We will demonstrate that the cultivation of JB and DNS in HT and LT regimes will extend the strawberry season by 10 months (March to Dec.) for local markets.

Weather conditions are ideal for raspberry cultivation in our area, dominated by cool days and sufficient sun light during summer and autumn. These conditions can extend the harvest season from early June to late December. The primocane-fruiting raspberries bear fruit in late summer and fall and later in winter, canes can be removed at ground level to allow new crop in spring. Primocane-fruiting raspberries can extend the season from late summer into fall while floricanes harvest is restricted to six weeks during summer (Pritts, 2008). Moreover, annual removal of primocanes can limit the annual cycle of pests and pathogens, thus decrease expenses for fungicides and insecticides. Cultivation of PFTR is a potentially profitable enterprise for small farmers on the Delmarva Peninsula. Moreover, use of HT cultivation of primocane will also improve fruit quality and season extension during fall months.    

Service Provider Interest:      

Agriculture service providers in this proposal comprises of county extension agent (2), urban agriculture agent (1), administrators and members of BIPOC farmer organization (2), veteran agriculture instructors (1), multi-disciplinary faculty members (4), socially disadvantaged growers (45), veteran growers (16), and 181 members of online coalition of growers and consumers on the Delmarva Peninsula.  We are expecting to develop a ‘Small Fruit Team’ (8 or 10 trained extension personnel) and trained farmers (45) during the three years of this project.  So far, only 2 extension agents (Urban Agriculture/Veteran agriculture instructor) committed  participation in this program. They will attend the workshops and help in extension outreach. Other Ag. extension agent on the Delmarva Peninsula will also be communicated to participate in this program. However, 10 farmers showed willingness to help other farmers after getting hand-on training through this program.        

Educational Approach

Educational approach:

Engagement:

Project PI, Ag. service providers, and recruited  local growers on the Delmarva Peninsula will communicate with other interested farmers to participate in this project over a period of 3-year. Each year educational materiel on previous workshops  will be provided to new growers to keep them up to date on subject matter.  Ag. service providers and farmers will use UMES small fruit plots for extension outreach events. In addition, UMES extension website will be provided to Ag. Service providers to communicate online or though the publication of factsheets. Educational PowerPoint will be shared with the Ag. Service providers to use during their independent workshops and one to one consultations.  

Surveys of service providers will be conducted each year in October and information will be collected on their extension outreach activities related to this project. Collected information will be used to verify teaching actions and further suggestions/development/modification will be incorporated  in the extension plan in the successive years.

Learning: 

Each year four-extension events will be organized during October (June Bearers strawberry sowing), April (Day Neutral Strawberry and Floricane and Primocane Raspberry sowing), June (June Bearers strawberry and Floricane raspberry harvest), and September (Day neutral and primocane raspberry harvest) of each year at UMES. In addition to above mentioned four workshops, two more workshops will also be conducted for US service veterans in Baltimore in association with NGO, TALMAR. Ag. service providers in association with project PI will participate in teaching and demonstration classes during these workshops.   

Educational approaches at each event will include a classroom presentation followed by the small fruit plot visit. All the practical trainings will be conducted at UMES experimental small fruit plots (low tunnels, high tunnels, and open bed) to observe the various phenology of fruit growth and development. Online classes will also be conducted using the Zoom platform. YouTube video will be created for field demonstrations and classroom teaching and link will be displayed on the UMES extension website and social media platforms (UMES- Horticulture Physiology Facebook Page; 200 growers are the current members on this page) to reach multiple  stakeholders. In addition, visits to small fruit team members farms will be facilitated to promote farmer-to farmer leaning. Printed and online material will be provided to attendees after each workshop and through email communication. 

We expect our program will enrich the following knowledge base of extension service providers and participating farmers to establish small-scale strawberry and raspberry cultivation plots to diversify fruit production on the small farms.

Summary:

During the 19th Small Farm Conference (11/4/2022-11/5/2022), 5 Ag. Service Providers and 23 Farmers were recruited for the three-year NE SARE PDP Training Project on Strawberry and Raspberry Season Extension at UMES. Two additional high tunnels were created for training and demonstration purposes to make this notion a reality. To accomplish Milestone-1, four workshops were held: two workshops were held at Therapeutic Alternatives of Maryland (TELMAR), Baltimore, MD, from 5/3/2023 to 5/4/2023. The other two workshops were held at UMES on October 7, 2023. In addition. The outcomes of the seminars were discussed with Ag. Service Providers during the American Society of Horticultural Science (ASHS) Annual Meeting in Orlando, Florida (8/1/2023). Strawberry cultivation, a vital component of horticulture, requires a comprehensive understanding of modern techniques to optimize yields. This workshop provided information to Ag. Service Providers and farmers on how use of raised bed machines, the characteristics of June-bearer strawberry varieties, and the selection of appropriate mulch for raised beds. Workshop focused on the following aspects. Machine Operation: Provided hands-on training on how to operate raised bed machines, emphasizing key features and adjustments for different soil types. Maintenance Techniques: Educated farmers on routine maintenance tasks to ensure the longevity and efficiency of the raised bed machines. This includes blade sharpening, belt adjustments, and lubrication.

Explained how these dimensions contribute to effective water drainage and soil warming. Soil Preparation: Guided farmers on proper soil preparation before using raised bed machines, including soil testing, amendment incorporation, and leveling. Workshop and education material also provided information on Mulch Selection: Discussed various mulching materials such as straw, plastic, or landscape fabric. Evaluated the pros and cons of each, considering factors like cost, insulation properties, and environmental impact. Application Methods: Provided guidance on proper mulch application techniques, emphasizing uniform coverage and thickness to maximize benefits. Mulch Maintenance: Educated farmers on routine mulch maintenance, including weed control, replenishment, and removal at the end of the growing season. Impact on Soil Temperature: Explained how different mulching materials can influence soil temperature, affecting strawberry growth and development. This information will aid farmers in choosing the most suitable mulch for their specific climate and soil conditions. Information was also provided on Strawberry Varieties for season extension using early, mid, and late June-Bearer: Understanding the differences between June-bearer strawberry varieties is crucial for farmers to make informed decisions based on their specific needs and growing conditions. Farmers learned June-bearer varieties produce a concentrated harvest over a shorter period, typically in late spring to early summer. Limited harvest window, requiring precise marketing and distribution planning. The impact of providing training on the use of raised bed machines, understanding June-bearer strawberry varieties, and selecting appropriate mulch for raised beds is evident in the verified changes observed in participants' knowledge, attitudes, skills, and actions. 1. Increased Knowledge: Participants indicated a considerable gain in their understanding of the complexities involved in operating raised bed machines. This included a thorough understanding of appropriate bed dimensions and soil preparation processes. Farmers enhanced their awareness of the distinguishing characteristics of June-bearer strawberry types, allowing them to make informed judgments based on their individual agricultural aims and local conditions. Mulching (Black and White type) workshops aided in the advancement of knowledge about various materials, application methods, and the impact on soil temperature regulation. 2. Attitude Shift: Participants expressed greater confidence in adopting raised bed machines, recognizing them as valuable tools for optimizing strawberry yields. The nuanced understanding of strawberry varieties fostered a more adaptable mindset, allowing farmers to embrace diverse cultivation strategies based on market demands and seasonal considerations. Attitudes towards mulching (white for day neutral and Black for June Bearers) also shifted, with participants acknowledging its importance in weed suppression, moisture retention, and overall plant health. 3. Skill Development: Hands-on training sessions provided participants with practical knowledge on how to operate and maintain raised bed machines. Farmers improved their ability to build beds, modify machine settings, and troubleshoot typical problems. Participants learned the significance of white and black type of mulches and their use for specific crops. They also learned how temperate controls flowering in strawberries and concept of day length. 4. Awareness and Action: The training workshops raised participants' knowledge of the interconnectivity of their growing method choices and the larger agricultural ecosystem. 2 farmers will plant combination of day neutral and June Bearer strawberries next season (2024) using bed raised machine to actively shift from conventional to raised bed farming practices. 1 farmer is planning to adapt U-Pick system of marketing for raised bed strawberry cultivation. All the participants improved their mulching skills for strawberry cultivation and will use black type of plastic mulch for June Bearer strawberry cultivation.   

Milestone #2: (April-2023)

4 Agriculture service providers and 8 farmers will be invited in the spring of 2023 at UMES small fruit plots to learn the phenology of day neutral strawberries (DNS) and floricane fruiting type (FFT) and primocane fruiting type (PFT) raspberries. Information on suitable varieties of DNS, FFT, and PFT will also be provided to the Ag. service providers.  Participants will also learn about the source of local availability of these plants.

Summary:

To accomplish Milestone-2, three workshops were conducted during May-November, 2023. Two workshops were conducted at Therapeutic Alternatives of Maryland (TELMAR), Baltimore, MD, from 5/3/2023 to 5/4/2023 for the socially disadvantaged beginning veteran farmers and 1 demonstration at UMES during the 20th Small Farm Conference (11/2/2023). 5 Ag. Service Providers and 15 farmers were also recruited for the 2024 NE SARE PDP Training Project on Strawberry and Raspberry Season Extension at UMES. Following information was provided on overview of day-neutral strawberries, emphasizing its distinct feature of continuous fruiting throughout the growing season. Advantages of Season Extension: Discussed the benefits of day-neutral strawberry production, focusing on how it helps farmers to lengthen harvest seasons and meet market demands over a longer period of time. Planting Demonstration: Given a live demonstration of planting day-neutral strawberries, demonstrated optimum procedures for bed preparation, planting depth, and spacing. Hands-on activities relevant to managing day-neutral strawberry plants, such as pruning procedures, pest management, and irrigation strategies, were demonstrated. Variety selection was described in detail for flavor, yield, and disease resistance. Information was provided on bareroot and plug plants and described about their benefits, planting methods, and suitability to certain growth environments. Discussed day-neutral strawberry soil requirements, sunshine exposure, and water management options. Provided fertilization suggestions for day-neutral strawberries at various growth stages. Participants were educated on the most common foliar diseases affecting day-neutral strawberries, as well as how to detect and control them early. Explained the relevance of eliminating early blossoms in order to divert energy toward plant establishment and fruit growth. Highlighted the yield potential of day-neutral strawberries as well as their great taste, stressing their consumer appeal. Provided insights into creating a UPick system, drawing clients to the farm for a one-of-a-kind and hands-on harvesting experience. Discussed effective customer engagement tactics such as farm tours, social media advertising, and community events. These workshops seek to equip farmers with the knowledge and skills required for successful day-neutral strawberry farming, season extension, and effective marketing by combining instructive sessions, hands-on exercises, and interactive demonstrations. Day-neutral strawberry cultivation, mulching for raised beds, irrigation and fertilizer management, liquid fertilizer application, the role of fertilizer injectors, marketing options, and agritourism have all had a significant impact, as evidenced by verified changes in participants' knowledge, attitudes, skills, awareness, and subsequent actions. 1. Increased Knowledge: Participants indicated a significant increase in knowledge about the benefits of day-neutral strawberries for season extension as season can be extended up to 9 months. Understanding the best mulching techniques (White type to regulate temperature during summer months) for raised beds, irrigation tactics (use of irrometer for irrigation scheduling) for the efficient use of water. The role of liquid fertilizers and the efficient use of fertilizer injectors for accurate nutrient administration. 2 farmers will use irrometer and fertilizer injector next season for the efficient management of water and fertilizer for sustainable strawberry cultivation. 2. Attitude Shift: A positive shift in attitudes towards adopting sustainable and season-extending practices was observed. Participants embraced the potential of day-neutral strawberries as a means of diversifying their crop calendars, leading to increased income at farm. Attitudes towards mulching (white outside and black inside) evolved, with participants recognizing its role in weed suppression, moisture retention, and soil health improvement. 3. Skill Development: Hands-on sessions improved practical abilities in day-neutral strawberry farming, including as planting, maintenance, and pest control. Participants mastered the application of liquid fertilizers with injector devices, maximizing nutrient delivery. Practical irrigation instruction on how to use irrometer prepared them to handle water efficiently in a variety of growing environments. 15 participants looking for a inexpensive type of fertilizer injector. 4. Awareness and Action: Participants are planning to diversify marketing tactics and   agritourism potential such as farm tours and community engagement. This move reflected a greater knowledge of the relationship between sustainable agriculture practices and successful marketing efforts. 4 participants are planning for UPick system and youth education at farm. Adoption of these techniques not only demonstrated a commitment to sustainable agriculture, but also helped to the economic viability and resilience of farming communities. The positive changes seen highlight the importance of focused education in promoting agricultural practices and developing a more sustainable and economically viable farming community. Workshops on raspberries will be conducted next year as these plants are still growing and we are in the process of developing trellis system. 

Milestone #3: (July-2023)

6 Agriculture service providers and 10 farmers will be invited in the summer of 2023 at UMES small fruit plots. Participants will learn how to construct inexpensive low tunnels (LT) to enhance the season extension of DNS. Participants will also learn how LT protects DNS from rainfall mediated fungal diseases. New team members who will join the project at later stages will receive previous educational materials to keep pace with the project. Local sources for LT materials will be provided to participants.   

Milestone 3:

Status: Complete

Date of Complete: 9/29/2023

Accomplishment:

Number of Service Provider: 3

Number of Farmer: 13

Summary:

To accomplish Milestone-3, one workshop was conducted during September, 2023. Workshop conveyed step-by-step construction of low tunnels using PVC pipes, twine, and tape. Participants were explained the advantages of low tunnels in season extension, disease reduction, and improved fruit quality. Greenhouse films play a crucial role in controlling the growing environment within a low tunnel, influencing factors such as light transmission, heat retention, and durability. Participants were provided information on types of greenhouse films such as infrared films, anti-condensation films, diffused films, acrylic films, ethylene vinyl acetate films, polycarbonate films, polyvinyl chloride films, and polyethylene films for low tunnel construction. Shared success stories of farmers who have implemented low tunnels for disease management and higher yield of day neutral strawberries. Participants were also provided information on the budget of low tunnel construction. The educational programs centered on low tunnel construction utilizing low-cost materials such as PVC pipes, twine, tape, and various types of greenhouse films resulted in significant and validated changes in participants' knowledge, attitudes, skills, awareness, and actions. 1. Increased Knowledge: The participants demonstrated a significant increase in knowledge regarding the building and application of low tunnels. There was a shared knowledge of the basic principles at first, but as the sessions went, participants gained deeper insights into material selection, structural design, and the vital role of different types of greenhouse films. They got a thorough understanding of how UV-blocking and UV-transmitting films can effectively manage diseases and insects’ movement within a low tunnel and how light spectrum control help to extend the growing season and improve fruit quality. Specially success story of Mr. Mike from Virginia, who documented higher day neutral strawberry yield using low tunnels, encouraged participants to use low tunnels for strawberry cultivation. 1 socially disadvantaged women farmer and 1 beginning farmer are planning to use low tunnels for strawberry cultivation and other crops. 2. Attitude Shift:  The workshop resulted in a positive shift in attitudes about the use of low tunnels as a viable and cost-effective alternative for improving strawberry cultivation. Participants initially questioned the simplicity of materials like PVC pipes, twine, and tape, but they gradually accepted these elements as accessible tools for producing efficient low tunnel structures. Participants recognized the economic benefits of adopting affordable materials without sacrificing efficacy as they became more aware of the possible benefits of various greenhouse films. 3. Skill Development: Participants developed actual skills that went beyond academic knowledge, such as learning to bend PVC pipes and precisely secure greenhouse films. Low tunnel construction became a concrete skill set, allowing participants to repeat the technique on their own farms. The acquired abilities extended beyond construction to include material selection, efficient assembly processes, and proper film installation, all of which contributed to the participants' confidence in properly implementing low tunnels. Participants documented how simple it is to build low tunnels. 4. Awareness and Action:  2 participants planning to put low tunnels up on their fields, displaying a proactive attitude to sustainable agriculture. The planned modification of light spectrums for season extension and the strategic use of UV-transmitting/blocking films for disease management demonstrated a greater grasp of the subtle elements impacting successful strawberry cultivation.

 Milestone #4: (October-2023)

8 Agriculture service providers and 12 farmers will be invited in the fall of 2023 at UMES small fruit plots. Feedback will be collected from the participants to further improve the extension outreach program. Participants will learn about the management/purchase/parts/operation of high tunnels (HT) and associated problems. Participants will also be informed about the NRCS grant for HT. Participants will also be informed and trained for SARE Farmer Grant. Participants will also be informed about the local sources of HT construction material. Members of team (8 or 10) and farmers who patriciate in the earlier workshops responds to annual verification to report on teaching and assistance about strawberry and raspberry cultivation.

Milestone 4:

Accomplishment:

Number of Service Provider: 5

Number of Farmer: 15

Summary:

High tunnels (HT) have become invaluable assets for farmers, providing controlled settings that boost crop output and protect against inclement weather. Comprehensive information is essential for arming farmers with the knowledge and resources required for successful high tunnel use. Management, buying considerations, maintenance, operation, and the possible NRCS grant for high tunnels are among the topics covered in workshops and programs. Participants were instructed on the day-to-day operation of high tunnels, with an emphasis on the following essential areas: Strawberry variety selection for high tunnel farming was provided, taking into account local climate conditions, soil quality, and market demand. Participants learned how to regulate ventilation and temperature in order to produce an ideal microclimate for strawberries. Effective water management was emphasized, including drip irrigation and the importance of maintaining adequate moisture levels for strawberry. Participants were given advice on how to make educated selections when acquiring high tunnels. Advice on selecting the best materials, size, and design to meet specific farming needs and environmental conditions. Understanding the many ventilation options available and selecting systems that are compatible with the crops being grown. Comparisons of various covering materials, such as single or double layers of polyethylene, and their effects on light transmission, insulation, and durability. Participants were also educated on the value of endwall design in improving air circulation and structural integrity. Detailed information was provided on high tunnel parts and operation by Mr. Brian, Farm Crew Member, UMES; I: Step-by-step instructions for assembling high tunnel frames while maintaining structural integrity and stability. II: Demonstrations of proper covering material installation, including fastening, tightening, and sealing to enhance performance. III: Instruction on how to use roll-up side walls to effectively control temperature and humidity. IV: Endwall management techniques for optimizing airflow and preventing damage during harsh weather events. Participants were trained on frequent high tunnel farming issues and viable solutions. Information was also provided on strategies for preventing and managing diseases and pests in the high tunnel environment, methods for preventing fungal illnesses by resolving condensation difficulties and maintaining ideal humidity level, and training on frequent inspection and maintenance techniques to guarantee high tunnel lifetime and functionality.

The educational programs focused on the building, management, procurement considerations, parts, operation of high tunnels (HT), and addressing associated difficulties resulted in deep and verifiable improvements in participants' knowledge, attitudes, abilities, and behaviors. These courses not only provided participants with practical skills, but they also facilitated a paradigm shift in their approach to high tunnel agriculture. 1. Increased Knowledge: Participants indicated a significant increase in knowledge across multiple aspects of high tunnel farming. Participants gained an in-depth understanding of high tunnel construction, structural concerns, covering materials, and the complexities of optimal operation through workshops and hands-on activities. They gained a thorough awareness of issues such as disease management, pest control, and structural maintenance, allowing them to make informed decisions. 1 team member/participant got NRCS funded high tunnel for day neutral strawberry cultivation in the Wicomico County, MD. Based on recommendation of this program, two high yielding day neutral strawberry varieties (Seascape and Portola) will be cultivated in the next season (2024). 2. Attitude Shift:  These workshops caused a beneficial transformation in participants' perceptions. Some participants may have initially seen high tunnel farming as complicated or out of reach. However, when they obtained hands-on experience and a greater grasp of the practical issues, their perception shifted noticeably. Participants began to regard high tunnels as not only practical but also necessary tools for optimizing strawberry yield, extending growing seasons, and managing weather hazards. Using high tunnels, we can demonstrate day neutral strawberry growing in Somerset County, MD until the third week of December. One female farmer will apply for NRCS-funded high tunnels in the next year. 3. Skill Development: Practical workshops were critical in participants' skill development. Participants developed skills in everything from building high tunnels and assembling their pieces to operating ventilation systems and addressing associated challenges. The information shared by the person who constructed these high tunnels at UMES created confidence that went beyond theoretical knowledge. Participants were not only educated, but also given the ability to implement what they learned in real-world high tunnel farming circumstances. Participants can order type of high tunnels they are interested in and similarly type of strawberry variety they want to grow for season extension. In fact, high tunnels can be the integral part of agritourism and can promote crop sale at the farm. Visitors can experience sustainable farming practices through high tunnels, which provide an immersive and educational component to agritourism. Exciting tours of these enclosed constructions provide insights into season extension, crop production, and technological integration. By demonstrating innovative and environmentally sensitive farming methods, high tunnels enhance the overall agritourism experience. 2 participants will allow UPick approach under high tunnels. 4. Awareness and Action: The workshop promoted a proactive approach, urging participants to include high tunnels into their overall farm management practices. In addition to strawberries, participants intend to cultivate other minor fruits and vegetables under high tunnels. One participant intends to use high tunnels to cultivate cut flowers and sweet potatoes. 5. Impact on Farming Practice: The verified changes in knowledge, attitudes, and skills have had a discernible impact on participants' farming practices. The implementation of high tunnels has resulted in extended growing seasons, improved crop yields, and enhanced resilience against adverse weather conditions. Participants reported a decline in disease incidences and improved pest management, indicative of the practical benefits derived from the workshops. 1 participant is embracing a dual approach, this participant plans to cultivate potted strawberries within high tunnels, offering not only luscious fruits but also thriving potted plants. By introducing this diverse product range at farmer markets, the participant aims to cater to both consumers seeking fresh, homegrown strawberries and those interested in cultivating their own berry-producing plants, creating a unique and appealing market proposition. 6. Adoption of Sustainable Practices: The workshops emphasized the need of sustainable and resource-efficient farming techniques in addition to technical considerations. Participants learned about soil health, water management, and organic pest control strategies. This broader perspective has contributed to a more environmentally responsible and sustainable approach to high tunnel agriculture. 2 socially disadvantaged participants shared their views to grow organic strawberries in high tunnels is a sustainable and environmentally friendly method. High tunnels produce a controlled environment that lowers the need for hazardous chemicals to control weeds and diseases. The enclosed building acts as a natural barrier against pests and reduces exposure to external toxins, making organic methods possible. This strategy is consistent with organic farming principles, encouraging soil health, biodiversity, and consumer well-being while providing a realistic answer for farmers committed to sustainable agriculture.
