Agriculture production emits significant amounts of nitrous oxide (N2O), a greenhouse gas with high global warming potential. The objectives this study were to examine whether different husbandry practices (tillage and plasticulture) following winter cover cropping would influence soil food web structure change in the community could help mitigate N2O emission vegetable plantings. Three consecu...

Agriculture represents about 10 % of total greenhouse gases (GHG) emission in the US, which carbon dioxide (CO2) and nitrous oxide (N2O) can greatly contribute to global warming climate change. Organic farming has been increasingly popular as it provides long-term environmental benefits including GHG mitigation. Judicious use cover crops crop rotation systems considered an effective approach su...

Biological nitrogen fixation (BNF) is a key ecosystem service rendered by legumes, but quantitative information lacking regarding BNF in the Texas Rolling Plains (TRP), an easterly portion of U.S. Southern Great where cool-season legumes can typically be grown as cash or cover crops dryland conditions. Using three diverse cropping systems studies (Site 1, long-term cotton [Gossypium hirsutum L....

Kura clover (Trifolium ambiguumM. Bieb.) grown in monoculture is difficult to harvest mechanically because of its decumbent growth habit, and legumes in general have poor ensiling characteristics. Our objectives were to assess forage yield, nutritive value, and silage characteristics of kura clover–winter wheat (Triticum aestivum L.) mixtures to determine usefulness as a silage crop. ‘Cardinal’...

Field assessments were conducted to examine the interplay between host plant and predation in complex agricultural mosaic on pea aphid clover and alfalfa races. In one experiment, we examined the relative fitness on clover race (CR) and alfalfa race (AR) pea aphids on broad bean, red clover and alfalfa alone. But because clover is typically grown in a more complex agricultural mosaic with alfal...

Estimation of clover content of mixed swards is difficult in practise. We are currently in the processof developing several on-farm methods for clover content estimation. 1. Photos with various clovercontents are published in the Internet. 2. Yield samples with known area from several points of thefield are separated for clovers and grasses and weighted. 3. The clover content of...

Strawberry is one of the most important berry crop grown around world and their consumption increases every year. The introduction new practices promoting farm sustainability long-term soil health in strawberry production systems very essential. Towards environment- climate-friendly farming intercropping can be used to improve microbiological activity biodiversity, reduce use pesticides mineral...

To determine if host plant abundance determined the size of clover root weevil (CRW) Sitona obsoletus larval populations, a study was conducted over 4 years in plots sown in ryegrass (Lolium perenne) (cv. Nui) sown at either 6 or 30 kg/ha and white clover (Trifolium repens) sown at a uniform rate of 8 kg/ha. This provided a range of % white clover content to investigate CRW population establish...

Cross-reactive antigens of clover roots and Rhizobium trifolii were detected on their cell surfaces by tube agglutination, immunofluorescent, and radioimmunoassay techniques. Anti-clover root antiserum had a higher agglutinating titer with infective strains of R. trifolii than with noninfective strains. The root antiserum previously adsorbed with noninfective R. trifolii cells remained reactive...
