Winter Cover Crops and Vinegar for Early-Season Weed Control in Sustainable Cotton
Weeds may be suppressed by winter cover crops and the use of organic herbicides such as vinegar. Black oat (Avena strigosa) and hairy vetch (Vicia villosa) winter cover crops were planted for 2 years as part of a sustainable production system for cotton in the Lower Rio Grande Valley of Texas, and were till-killed each spring prior to cotton planting. Palmer amaranth (Amaranthus palmeri), commo...
متن کاملResponse of Maize to Cover Crops, Fertilizer Nitrogen Rates, and Economic Return
17 Maize is the world’s most widely grown cereal on the basis of Mg produced (FAO, 2014). Nitrogen fertilizer applied to cropland is a considerable portion of the cost and energy input associated with nonlegume crop production (Liebman et al., 2012). When N is lost from cropland, it represents both a fi nancial loss to producers and has a potentially negative impact on the environment (Vetsch a...
متن کاملWinter cover crops on processing tomato yield, quality, pest pressure, nitrogen availability, and profit margins
Much of cover crop research to date focuses on key indicators of impact without considering the implications over multiple years, in the absence of a systems-based approach. To evaluate the effect of three years of autumn cover crops on subsequent processing tomato (Solanum lycopersicum L.) production in 2010 and 2011, a field split-split-plot factorial design trial with effects of cover crop t...
متن کاملWeed Control with Cover Crops in Irrigated Potatoes
Field experiments at Oakes, ND, USA in 2010 and Carrington, ND, USA in 2011 were conducted to evaluate the potential for cover crops grown in the Northern Great Plains, USA in order to reduce weed emergence and density in irrigated potatoes. Treatments included five cover crop treatments and three cover crop termination treatments. Termination of cover crops was done with glyphosate, disk-till,...
