Cover crops can harbor both harmful and beneficial arthropods (1, 3). Damage to cover crops themselves is rarely of concern; more important is the possibility that pests harbored amid cover crops may disperse to adjoining cash crops [see Kennedy and Margolies (31) for a discussion of the dynamics of such mobile pests]. Here, I explore the roles that cover crops play in the life cycles and popul...

The quality and quantity of the influence that atmospheric CO2 has on crop growth is still a matter of debate. This study’s aim is to estimate if [CO2] will have an effect on biomass yields at all, to quantify and spatially locate the effects and to explore if an elevated photosynthesis rate or water-use-efficiency is predominantly responsible. This study uses a numerical carbon-based crop mode...

Effluent from a swine (Sus scrofa domesticus) lagoon is often applied repeatedly to nearby fields because of logistical constraints and costs of transportation. To minimize accumulation of soil nutrients and sustain use of spray field, best management practices must maximize the rates of removal of manure nutrients. Research determined summer hay and nutrient yields of bermudagrass [Cynodon dac...

Abstract. Nitrogen (N) fertilizer inputs to agricultural soils are a leading cause of nitrous oxide (N2O) emissions. Legume cover crops an alternative N source that can reduce N2O emissions compared N. However, our understanding episodic flux following crop incorporation by tillage is limited and has focused on single-species crops. Our study explores whether increasing functional diversity wit...

Breeding of grain crops for phytoimmunity in the FSBSU FASC Northeast is carried out conditions natural and artificial epiphytotics. Every year, more than 1000 samples winter rye, spring soft wheat, barley oats their own breeding from VIR collection are studied. In studies conducted on snow mold, root rot, powdery mildew, brown stem rust, septoria blight, fusarium head ergot; wheat – loose smut...
