In previous crop rotation research, adult emergence traps placed in plots planted to Cuphea PSR-23 (a selected cross of Cuphea viscosissma Jacq. and Cuphea lanceolata Ait.) caught high numbers of adult western corn rootworms, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), suggesting that larvae may have completed development on this broadleaf plant. Because of this observat...

Agricultural production in the Midwestern US is highly concentrated with 85% percent of cropland acreage planted to only corn and soybeans (NASS, 2006). Crop specialization has improved the productivity and market efficiency of grain based commodity crops, but maintaining profitability has become increasingly difficult as input prices continue to rise while grain prices fluctuate substantially ...

watershed scale irnpact. Our objective was to estimate the watershed scale impact of grass buEers by comparing sediment and agichemical losses from two adjacent 14 1 165 hectare watersheds, one with conservation buffers and one without. Rainfall derived m o f f events frorn 2002-2003 were monitored for water runoff, TSS, phosphorous and atrazine loss. A conservation-watershed included 0.8 Ism o...

maize (zea mays l.) is one of the most important crops that used for food, feeding and industrial products and in iran a developing cultivation. in order to study of corn s reactions (hybrid bc666) to supply nutrients to organic nutrition (bacteria and manure) as summer sown in climate conditions of lorestan. an experiment was conduct in meteorology station of lorestan s agriculture research fi...

Crop production is reduced by insufficient and/or excess soil water, which can significantly decrease plant growth and development. Therefore, conservation management practices such as cover crops (CCs) are used to optimize water dynamics, since CCs conserve water. The objective of this study was determine the effects on dynamics a corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] rotation at...

Soil nitrogen cycling microbial communities and functional gene α−diversity indicate soil ecological functions potentials. Crop rotation plans affect fractions these indicators. We sequenced samples from four crop (fallow, winter wheat monoculture, pea-winter wheat-winter wheat-millet rotation, corn-wheat-wheat-millet rotation) in a long-term field experiment. examined how changed with regulate...

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...
