Seasonal fluctuations in field populations of Meloidogyne incognita, Pratylenchus zeae, P. brachyurus, Criconemoides ornatus, Trichodorus christiei, and Helicotylenchus dihystera on monocultured corn, cotton, peanut, and soybean were determined monthly for 4 yr. Population densities of M. incognita were greater in corn and cotton plots than in peanut and soybean plots from July until January. T...

The Moderate Resolution Imaging Spectrometer (MODIS) Normalized Difference Vegetation Index (NDVI) 16-day composite data product (MOD12Q) was used to develop annual cropland and cropspecific map products (corn, soybeans, and wheat) for the Laurentian Great Lakes Basin (GLB). The crop area distributions and changes in crop rotations were characterized by comparing annual crop map products for 20...

The use of crop practices to reduce the weed community is an ally integrated management. Given this, study aimed identify a composition and infestation in soybean area under different predecessor crops implanted years. experiment was carried out 2019/2020 harvest Dourados, MS. experimental design randomized block with nine treatments. treatments were composed autumn-winter crops. cultivation: c...

greatest proportion of the beneficial effects of crop rotation, but other factors, including reduced weed, disease, Increased N availability is often associated with the beneficial efand insect problems, can also be important. fects of rotating grain and legume crops. Our objective was to utilize yield response data from two long-term studies to determine the Corn is now commonly grown in a 2-y...

Two temperate corn (Zea mays) hybrids (Pioneer 3320 and Northrup King 508), two tropical corn cultivars (Pioneer X304C hybrid and Florida SYN-1 experimental open pollinated cultivar), the sorghum (Sorghum bicolor) x sudangrass (Sorghum sudanense) hybrid DeKalb SX-17, and the sorghum hybrid DeKalb FS25E were compared for effect on nematode densities and forage yield in three plantings (one singl...

Swine and rats demonstrated the same response factor (i.e., the average amount of corn amended with trichothecenes consumed by animals per the average amount of uncontaminated corn consumed by animals) for consumption of corn amended with 40 ppm of either T-2 toxin or diacetoxyscirpenol Rat response factor for corn containing 40 ppm of vomitoxin was 1.8 times more than corn containing either T-...

Objectives of this study were to compare ethanol production between normal and waxy corn using a cold fermentation process and to understand effects of starch structures and properties on ethanol production. Ethanol yields positively correlated (p < 0.01) with starch contents of kernels of the normal and waxy corn. The average starch-ethanol conversion efficiency of waxy corn (93.0%) was substa...

Progress in corn improvement research has produced varieties with higher concentrations of certain nutrients. Normally, corn contains about 3.5% ether extract which is relatively well utilized by pigs. Three varieties of corn with higher oil content and improved fatty acid profile relative to conventional corn were recently developed. The utilization of varieties of corn that contain higher oil...

An experiment was conducted to determine the true ileal digestibility (TID) and the true total tract digestibility (TTTD) of acid-hydrolyzed ether extract (AEE) in extracted corn oil, high-oil corn, distillers dried grains with solubles (DDGS), corn germ, and high protein distillers dried grains (HP DDG) and to compare these values to the TID and TTTD of AEE in full-fat soybeans. Nineteen barro...

the chemical and fermentative parameters of three fresh forages and silages of sorghum including sweet, pegah and speedfeed varieties were compared with corn using in vitro method, also degradability coefficients of forages and silages were determined by in situ method. forages were planted in the same condition and harvested in soft dough stage, then ensilaged in four replicates for each time ...
