Brassica cover crops are new to the mid-Atlantic region, and limited information is available on their N uptake capabilities for effective N conservation. Forage radish (Raphanus sativus L. cv. Daikon), oilseed radish (Raphanus sativus L. cv. Adagio), and rape (Brassica napus L. cv. Dwarf Essex) were compared with rye (Secale cereale L. cv. Wheeler), a popular cover crop in the region, with reg...

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,...

Despite the dynamic nature of annual cropping systems, few studies have investigated how structure predator communities and their interactions with prey corresponds crop seasonality. Adding winter habitat, such as cover crops, improves soil health likely contributes seasonal habitat availability for arthropod communities. Stable may lead to functionally diverse predatory associated ecosystem se...

Stale seedbeds are used by organic growers to reduce weed populations prior to crop planting. Ryemulches, derived from mechanically killed (rolled and crimped) winter rye cover crops, can serve the same purpose for spring-planted organic crops. Both methods can also be employed by conventional growers who face looming problems with herbicide resistant weeds. The objective of this research was t...

Escalating energy and fertilizer N prices have renewed farmer interests in methods that reduce manure management costs and enhance the fertilizer value of manure. At the same time, air quality legislation seeks to mitigate ammonia loss from animal operations. We compared two dairy heifer management practices on manure N capture and recycling through crops: the conventional practice of barn manu...

introduction amount and vertical distribution of leaf area are essential for estimating interception and utilization of solar radiation of crop canopies and, consequently dry matter accumulation (valentinuz & tollenaar, 2006). vertical distribution of leaf area is leaf areas per horizontal layers, based on height (boedhram et al., 2001). above-ground biomass is one of the central traits in func...

Introducing cover crops is a form of ecological intensification that can potentially reduce local, regional and global environmental impacts soybean cropping systems. An assessment multiple (global warming potential, eutrophication, soil erosion organic carbon variation) was performed on continuous system in the U.S. upper Midwest. Four sequences were assessed compared: with winter camelina, fi...

Abstract Various winter crops can be produced before soybean [ Glycine max (L.) Merr] in the Southeast United States, however effect of these on productivity and optimum maturity group to use following various remains unknown. This experiment was conducted five environments across North Carolina 2019 2020 understand crop (MG) productivity. Winter investigated included cereal rye ( Secale cereal...

Phenamiphos applied at 6.7 kg ai/ha through a solid set or a center pivot irrigation system with 28 mm of water effectively controlled root-knot nematodes, Meloidogyne incognita, and resulted in greater snap bean growth and yields irrespective of growing season, tillage method, or cover crop system. The percentage yield increases attributed to this method of M. incognita control over nontreated...

In a view of the predicted drought that has appeared in recent years and water shortage growing season, which is getting worse every year, problem retention soil increasing its humidity becomes exceptional importance. The field experiment was carried out 2009–2012 on grey brown podzolic developed from loess formations covering cretaceous marls with granulometric composition corresponding to med...
