On-farm testing of organic weed control strategies in Indiana

Nashville, IN - In this on-farm study, organic vegetable producer Dale Rhoads tried out several organic herbicide materials and flaming in conjunction with a ‘stale’ seedbed to reduce the time and cost of hand-weeding leafy greens beds. The materials tested were Matran 5 (now reformulated and sold as Matran EC), two different vinegar solutions diluted to 13% and 10%, and Burnout II.

Participatory Screening of Broccoli Varieties for Summer Production in Organic Systems in Western North Carolina—Year 3: Phase II--On-farm Trials

There is high demand for organic broccoli in the Southeast, as shown in a 2013 market survey by Carolina Farm Stewardship Association, which revealed that broccoli is one of the top organic produce items in short supply. Broccoli can be produced most anywhere in the spring and fall, but summer production is limited to cooler growing areas.

Deploying microbes as a seed treatment for protection against soil-borne plant pathogens

Plant diseases, especially those caused by soil-borne seed infecting pathogens, pose a serious threat to the production of both greenhouse and field crops. Conventional farming operations often use fumigants and chemical seed treatments, which can be harmful to human health and the environment, for controlling seed and seedling pathogens.

Snap Beans With Enhanced Nitrogen-Use Efficiency for Organic Production -Year 1

The snap bean is a vegetable in the Fabaceae family and does have the capacity to fix atmospheric nitrogen through a symbiotic relationship with Rhizobium spp. Historically, easy access to nitrate-based soil amendments at a relatively low cost has precluded the need to develop cultivars with improved nitrogen-use efficiency (NUE). Excessive fertilizer applications containing 40 to over 100 lbs. of N / acre have resulted in leaching and the contamination of ground and surface water.

Participatory Screening of Broccoli Varieties for Organic Systems in Western North Carolina

Identifying appropriate varieties for organic production in the mountains of Western North Carolina is considered a research priority by local growers.

Farm Made: A Guide to On-Farm Processing for Organic Producers

There are two obvious barriers organic producers face when they consider on-farm processing. The first is psychological. On-farm processing can appear intimidating and beyond reach, on one hand; on the other, it may seem unnecessary to someone who is already “adding value” by raising crops or livestock organically. The second barrier—a more pragmatic one—is the lack of good, producer-friendly information on small-scale organic processing and handling.

Establishing breeding populations for organic broccoli, sweet corn, and red kale varieties

Organic farmer interest in on-farm plant breeding has been on the rise due to a lack of available germplasm adapted to organic systems, a growing awareness of the value of regionally adapted varieties, and consolidations in the seed industry that have led to a decline in varietal offerings.

Managing Natural Habitat Can Aid in Organic Pest Control

Summary

Determing habitat requirements for natural enemies of farm pests

Coordinator: Rebecca Chaplin-Kramer, University of California, Berkeley

Maintaining a healthy population of beneficial insects that serve as natural enemies to crop pests is an important component of pest management for organic farmers. To do so, we must understand the habitat requirements of these insects.
