Intercropping Cowpea with Vegetables Can Increase Yields

GREENSBORO, North Carolina- Intercropping cowpea with vegetable crops can increase yields up to 50% according to a new report from the Southern Sustainable Agriculture Research and Education program. Cowpea is a nitrogen-fixing legume originally domesticated in Africa. Known for its black-eyed peas that are common in southern cooking, it has a high tolerance for sandy, […]

Organic Control of White Mold in High Tunnels

The fungus Sclerotinia sclerotiorum infects many of the cool-season crops produced in Kentucky. This SARE-funded video presents information on the high tunnel production system most commonly used in Kentucky; the disease cycle of S. sclerotiorum; and two control tactics compatible with national organic standards, solarization and biofumigation.

Cover Crops and Biodegradable Mulches for Weed Control

AUBURN, Alabama – High biomass cover crops are effective in controlling weeds in vegetable production, while contributing to higher produce yields, Auburn University researchers have found. In addition, pre-emergence herbicide applications can be eliminated from weed management programs in the presence of heavy residues from cover crop mixtures. Through a Southern Sustainable Agriculture Research and […]

Researchers Recommend New Strategies to Suppress Southern Potato Blight

PAINTER, Virginia – Earlier planting dates coupled with disease-tolerant cultivars of potatoes are recommended strategies to suppress southern potato blight, according to Virginia Tech researchers. The fungal disease, caused by the soil born pathogen Sclerotium rolfsii, affects the stems of the plants and produces lesions on the tubers, impacting quality and yields. In a Southern […]

Agroforestry an Alternative for Farmers Transitioning Away from Tobacco Production

BEREA, Kentucky – A Kentucky farmer, exploring alternatives for tobacco production, has found that elements of an agroforestry system may prove viable to increasing farm profitability and providing environmental benefits. Through a Southern Sustainable Agriculture Research and Education (SSARE) Producer Grant, Matthew Wilson of Rindlewood Farm studied the feasibility of incorporating sweet sorghum and pasture […]

Exploring Alternative Methods for Controlling A Major Pest in Sweet Sorghum

LEXINGTON, Kentucky – University of Kentucky researchers are exploring alternative methods for controlling sugarcane aphid in sweet sorghum, a major crop for farmers in the state. Through a Southern Sustainable Agriculture Research and Education (SSARE) On-Farm Research Grant, entomologist Nathan Mercer and his colleagues are studying a combination of parasitoids and insecticidal soaps as a […]

The Performance of Cover Crops in Minimally Tilled Forage-based Grazing Systems

In a Southern SARE-funded Graduate Student Grant (GS15-152), “Evaluation of Winter Annual Cover Crops Under Multiple Residue Management: Impacts on land management, soil water depletion, and cash crop productivity,” Texas Tech University researchers investigated five cover crops species as potential complements to a warm-season beef-stocker grazing system. The impact of the project was two-fold: Stabilize the soil surface from excessive wind erosion and desiccation; and strengthen rural communities by ensuring the persistence of profitable agriculture in the region.

Using Multispectral Imaging Technologies to Maximize Yields in Sugarcane

HOUMA, Louisiana – When it comes to profitable sugarcane, the goal of every grower is to achieve the highest possible sucrose yield at the lowest production cost possible. Sugarcane yields correlate with nitrogen application, and as producers continue to get squeezed between decreasing acreage and higher input costs, such as fertilization, they are looking for […]

Cover Crops Have Benefits in High Tunnels

GLENWOOD, Georgia – Barley and hairy vetch growing vigorously in a high tunnel at Lola’s Organic Farm in southeast Georgia were going to seed. It was mid-April. Time to mow and prepare the soil for the summer’s cash crops: ginger and turmeric. Since last year, couple Jennifer Taylor and Ron Gilmore – USDA certified organic […]

NCSU Explores Regionally Adapted Legumes as Forage and Cover Crops

RALEIGH, North Carolina – North Carolina State University researchers are working to expand the portfolio of crops farmers can use in grain, forage and cover crop production. Through a Southern Sustainable Agriculture Research & Education (SSARE) Graduate Student grant, student Rachel Atwell Vann and organic cropping specialist Chris Reberg-Horton field tested 19 winter pea (Pisum […]

Get the Most Out of Forage Systems for Goats with Sunn Hemp

TUSKEGEE, Alabama – Small ruminant producers in the Southeast can potentially graze their goats year-round on a forage-based production system by incorporating a summer legume, such as sunn hemp, into the traditional bermudagrass pasture. Tuskegee University animal scientist Byeng-ryel Min found that a summer sunn hemp/bermudagrass forage mixture, or sunn hemp alone, followed by winter […]

Cover Crops Acting as Trap Crops Protect Vegetables from Pests

LIVE OAK, Florida – For farmers in central Florida, planting cover crops in strips as a trap crop alongside cash crops is proving to be a highly effective method for attracting beneficial insects and controlling pests. Farmers have been so pleased with the results that they have fully adopted the Integrated Pest Management (IPM) strategy […]

Cover Crops Reduce Pest Numbers and Improve Cash Crop Yields

GAINESVILLE, Florida – Preliminary research from University of Florida has found that incorporating root-knot nematode-resistant cover crops in a perennial peanut rotation reduces pest numbers in the cash crop and improves yields. The results may be helpful for producers who choose top-yielding, yet susceptible, peanut cultivars, as well as resistant cultivars that historically carry a […]

Perennial Peanuts Shine as N Fertilizer Alternatives in Forage Production

MARIANNA, Florida – Perennial peanuts incorporated in forage grass production, such as bermudagrass and bahiagrass, continue to shine as nitrogen fertilizer alternatives to commercial inputs, according to University of Florida research. Based on the results of a Southern Sustainable Agriculture Research & Education (SSARE) Graduate Student Grant, warm-season perennial legumes, in some cases, reduced nitrogen […]

Breeding Organic Corn Varieties to Resist GMO Contamination

KNOXVILLE, Tennessee – Breeders with the University of Tennessee are developing organic corn varieties that cannot be contaminated by GMO corn (genetically modified organisms) via cross-pollination. A corn ear from a Ga1s line pollinated with pollen from a GMO corn hybrid (upper ear with no seeds) and the same line pollinated with pollen from a […]

Cover Crops for Weed Management in Row Crops

The use of cover crops for weed control can help conventional producers combat herbicide-resistant weeds and organic producers reduce dependency on cultivation as their primary weed control mechanism.

Integrating Perennial Peanut into Grass Pastures

GAINESVILLE, Florida — Rhizoma peanut (commonly known as perennial peanut) is a warm-season perennial legume well adapted to Florida. It has high digestibility (65-75%) and crude protein concentrations (15-20%), that can really boost livestock performance. Integrating rhizoma peanut into bahiagrass pastures can almost double livestock performance, compared to bahiagrass alone (Figure 1). Rhizoma peanut also […]

Diversifying in the Texas High Plains: Examples of agroecosystems models

The following system configurations are examples of the diversified crop/livestock production practices that have been studied across the Texas High Plains since 1997. These systems have been tested against cotton monoculture –a subsurface drip-irrigated system farmed with conventional cultural practices recommended for the High Plains region.
