A four-year rotation is desirable for potatoes. Proper rotation of crops is one necessary practice for avoiding the holding over of potato diseases in the soil. For potato wilt control at least a four-year rotation should be used. The one shown here makes use of corn, grain, clover, and potatoes. The best basic crop rotation for Western Oregon is grain, clover seed, clover hay, and a cultivated...

This study aimed to evaluate levels of potassium and nitrogen fertilizer inversion in the black oat crop on corn yields. The experimental design was a randomized block with subdivided plots three repetitions. treatments were four fertilization strategies, two managements (forage cover crop). strategies involved winter (oats) summer (corn) application, respectively, following combinations (200-0...

Colony counts which approximated those in a habitat-simulating, rumen fluid-agar medium (RFM) were obtained in medium 10, a medium identical to the RFM except for the replacement of rumen fluid with 1.5 x 10(-6)m hemin, 0.2% Trypticase, 0.05% yeast extract, and a 6.6 x 10(-2)m volatile fatty acid mixture qualitatively and quantitatively similar to that in rumen fluid. Single deletion of Tryptic...

The objective of this study was to evaluate the effects of sowing procedures and the seed sowing rate of kudzu (Pueraria phaseoloides cv. ‘Comum’) in corn on corn plant development, forage dry matter production, weed infestation and soybean plant development and yield. The kudzu seeds were either broadcasted over the terrain or sown in furrows (in the main plots) at rates, in both cases, of 400...

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 ...

Diversified crop rotation may improve production efficiency, reduce fertilizer nitrogen (N) requirements for corn (Zea mays L.), and increase soil carbon (C) storage. Objectives were to determine effect of rotation and fertilizer N on soil C sequestration and N use. An experiment was started in 1990 on a Barnes clay loam (U.S. soil taxonomy: fine-loamy, mixed, superactive, frigid Calcic Hapludo...

Four experiments were conducted to investigate the effects of ractopamine hydrochloride (RAC) on ruminal fermentation and proteolysis. In Exp. 1, in vitro gas and VFA production was measured in flasks incubated with 0, 0.226, 2.26, 22.6, and 226.0 mg of RAC/L of buffered ruminal fluid. Ractopamine hydrochloride had a quadratic effect on in vitro gas production (P < 0.05; 177, 181, 185, 190, and...

A limited irrigation study involving four cropping systems and evaluating crop rotations was initiated at the Southwest Research-Extension Center near Tribune, KS, in 2012. The were two annual (continuous corn continuous grain sorghum) 2-year (corn-grain sorghum corn-winter wheat). In 2020, yields similar for all rotations, although averaged across past 8 years, greater following wheat than cor...
