investigating the decomposition of crop residues using woodborn and soilborn saprophytic fungi this experiment was conduceted to evaluate the effect of some fungi on decomposition of crop residues. crop residues from rice, wheat, cotton, canola and soybean were inoculated with pleurotus ostreatus, phanerochaete chrysoporium, aspergillus niger and trichoderma viride in vitro. after 30 days, hemi...

Wheat/soybean rotation is an important double-cropping system in the Huang-Huai-Hai plain of China. Continuous soybean cropping could cause soil quality deterioration and plant growth inhibition. However, effects continuous wheat/soybean on rhizosphere microbes remain largely unknown. In this study, we compared yield microbial community between winter wheat/summer (W/S) with two harvests one ye...

This research was conducted at the Department of Soil Science, University of Nigeria Teaching and Research Farm in 2008 and 2009 growing seasons. The objective was to evaluate the effects of edible grain legumes (cowpea and soybean) and velvet-bean/maize rotations on soil chemical properties and the contribution of these chemical properties to rotation benefit conferred on the maize by velvet-b...

Cellulose nanofibrils (CNF) were incorporated in water-in-oil (W/O) microemulsions and emulsions, as well as water-in-oil-in-water (W/O/W) multiple emulsions using soybean oil. The addition of CNF to the aqueous phase expanded the composition range to obtain W/O/W emulsions. CNF also increased the viscosity of the continuous phase and reduced the drop size both of which increased the stability ...

Glyphosate-resistant (GR) volunteer corn is a troublesome weed in soybean fields in a corn-soybean rotation as well as in corn fields in a continuous corn production system. The objectives of this study were to evaluate the impact of (1) different densities of GR volunteer corn on soybean yields, present as individual plants or clumps, controlled at fourth trifoliate (V4), sixth trifoliate (V6)...

Soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), is currently the most important insect pest of soybean (Glycine max (L.) Merr.) in the United States and causes significant economic damage worldwide, but little is known about the aphid at the molecular level. Mariner-like transposable elements (MLEs) are ubiquitous within the genomes of arthropods and various other invertebrates....

Prolonged, continuous rainfall is the main climatic characteristic of autumn in Southwest China, and it has been found to cause mildew outbreaks in pre-harvest soybean fields. Low temperature and humidity (LTH) stress during soybean maturation in the field promotes pre-harvest mildew, resulting in damage to different organs of soybean fruits to different extents, but relatively little informati...

Producers are frequently most interested in economic comparisons of various cropping systems. We compared continuous corn (Zea mays L.) and continuous soybean [Glycine max (L.) Merr.] with 2-, 3-, and 5-year rotations, the latter two including wheat (Triticum aestivum L.) and alfalfa (Medicago sativa L.), using either chisel plow or no-tillage practices. Crop yield and returns to land and manag...
