Research was conducted on silt-loam Alfisols at the Pine Tree Branch (PTBS) and Cotton Branch (CBES) Experiment Stations. Prior to the initiation of this study, both study locations were cropped under CT; thus the results of this study represent a short-term NT history. Previous crops were sorghum (Sorghum bicolor L.) and soybean at PTBS and CBES, respectively. The research area was established...

In 1987, the United States Department of Agriculture (USDA-ARS) National Sedimentation Laboratory, in cooper­ ation with the Mississippi Agricultural and Forestry Experi­ ment Station (MAFES) and the Natural Resources Conservation Service (NRCS), initiated an interdisciplinary research project to develop profitable and environmentally sustainable conservation production systems for silty upland...

Soybean (Glycine max L.) is considered as one of the major sources of oil and protein. In this study, the effects of vermicompost (VC) and sulfur (S) on soybean photosynthesis responses, yield, and grain quality were studied. To this end, a split-plot design field experiment based on randomized complete blocks with nine treatments and three replications was conducted in Aligudarz city Lorestan ...

Total carotenoids (TC) were determined as a measure of total xanthophylls in grain flours and grits, by new validated spectrophotometric method based on A1cm1%-approach. The general analytical procedure is easily adjustable to different samples, the number of extraction steps depending on TC concentration in the sample. Basically, two methods have been suggested: the rapid one for low-TC sample...

The objectives of this work were to evaluate two greenhouse screening methods for sudden death syndrome (SDS) and to determine which one is best correlated with fi eld resistance of soybean genotypes. The evaluations were done with three sets of genotypes that were classifi ed as partially resistant, intermediate, and susceptible to SDS based on previous fi eld evaluations. These three sets wer...
