This study was conducted to determine winter wheat yields following both mixtures and single-species plantings of spring-planted cover crops. The study was conducted at Akron, CO, and Sidney, NE, during the 2012–2013 and 2013–2014 wheat growing seasons under both rainfed and irrigated conditions.
Traditional cover cropping systems for nematode management seldom consider weed and soil nutrient management concurrently. Integrating cover crops suppressive to plant-parasitic nematodes with a cover crop mulching system could improve traditional approaches. Two ﬁeld experiments were conducted in 2003 and 2004 to evaluate ‘Tropic Sun’ sunn hemp (Crotalaria juncea) and ‘Iron Clay’ cowpea (Vigna unguiculata) […]
Herbicide and Cover Crop Residue Integration for Amaranthus Control in Conservation Agriculture Cotton and Implications for REsistance Management
Field experiments were conducted from autumn 2006 through crop harvest in 2009 at two sites in Alabama to evaluate the effect of integrated weed management practices on Amaranthus population density and biomass, cotton yield, and economics in glyphosate resistant cotton.
Planting Date and Seeding Rate Effects on Sunn Hemp Biomass and Nitrogen Production for a Winter Cover Crop
Sunn hemp (Crotalaria juncea L.) is a tropical legume that produces plant biomass and nitrogen (N) quickly. Our objectives were to assess the growth of a new sunn hemp cultivar breed to produce seed in a temperate climate and determine the residual N eﬀect on a rye (Secale cereale L.) cover crop in east-central Alabama […]
There is a potential in the southeastern US to harvest winter cover crops from cotton (Gossypium hirsutum L.) ﬁelds for biofuels or animal feed use, but this could impact yields and nitrogen (N) fertilizer response. An experiment was established to examine rye(Secale cereale L.) residue management (RM) and N rates on cotton productivity. Three RM […]
This project examined the effects of three winter cover crop species grown singly and combined in multispecies mixtures on selected biological indicators of soil health and determined the changes of these indicators over a three-year period. The cover crops included single species and mixtures of cereal rye (Secale cereale L.), crimson clover (Trifolium incarnatum L.), […]
Although there is evidence that cover crops enhance soil microbial diversity and activity, limited information is available about the impact of cover crops on biological indicators of soil health. The use of multi-species cover crop mixtures has been promoted nationwide to enhance soil health; however, little data are available demonstrating the benefits of cover crop […]
