The effects of an autumn-planted, spring-killed, grass cover crop (Elymus trachycaulus [Link] Gould ex Shinners) on populations of Diabrotica virgifera virgifera LeConte and its predator community were evaluated in South Dakota maize fields over two seasons. Abundance and size of D. virgifera larvae and adults and sex ratio of adults were measured in maize produced under two treatments (i.e., a...

Rye (Secale cereale L.) is important food crop in Russia. The study of the genetic diversity crops carried out using molecular markers. To identify effective primers, ISSR (Inter Simple Sequence Repeats), a method for determining DNA polymorphism, was used.The selection primers according to largest number polymorphic fragments, their clear amplification and reproducibility repeated PCR. Of 22 a...

Conservation management practices such as no-tillage and cover crops can decrease soil’s susceptibility to wind erosion, but adoption of these has been limited on the Texas High Plains (THP) where producers are concerned with crop water usage. The objective this study was evaluate impact cotton (Gossypium hirsutum L.) lint yield soil content in a deficit irrigated cropping system. Soil observed...

The anticipated increases in environmental variability associated with climate change may lead to enhanced abiotic plant stresses (e.g., heat stress, drought etc.) resulting greater inter-annual yield fluctuations and higher crop production risk. While there has been increasing attention adaptation measures, is little evidence available on how agronomic management strategies maintain stable yie...

Despite differences between the cover crop growth and decomposition phases, few greenhouse gas (GHG) studies have separated these phases from each other. This study's hypothesis was that a living reduces soil inorganic N concentrations water, thereby reducing N2O emissions. We quantified effects of fall-planted cereal rye (Secale cereale L.) (2017, 2018, 2019) on following spring's temperature,...

Abstract Cover crops (CCs) can reduce nitrogen (N) loss to subsurface drainage and be reimagined as bioenergy for renewable natural gas production carbon (C) benefits (fossil fuel substitution C storage). Little information is available on the large-scale adoption of winter rye these purposes. To investigate impacts in North Central US, we used Root Zone Water Quality Model simulate corn-soybea...

Abstract The southeastern United States has a long history of soil degradation due to intensive agriculture and climatic factors. Conservation management practices such as cover cropping aim improve productivity restore health. Our objectives were evaluate the performance crops their short‐term effects on health indicators for two types. Cover crop experiments conducted at Wiregrass (WREC) Tenn...

Abstract Synchronizing crop residue decomposing and releasing nitrogen with subsequent cash needs provides benefits for ecosystems, but it is difficult to carry out. This study aimed investigate the trend of decomposition vetch ( Vicia sativa ), rye Secale cereal e) mixed (rye + vetch) cover residues as well release after incorporating them into soil during 12 weeks potato growth season by usin...

Mustard (Brassica spp.) cover crop residue has been reported to have signifi cant ‘biofumigant’ action when incorporated into soil, potentially providing disease suppression and yield improvement for the succeeding crop. The effects of growing over-winter mustard cover crops preceding processing tomato (Lycopersicon escultentum Mill.) production were investigated in six fi eld trials in the Sac...
