A microplot experiment was conducted in soybean–wheat cropping system at New Delhi during 2010-11 and 2011-12 to study the effect of continuous or cyclic tillage, viz., conventional tillage (CT) and zero-tillage (ZT) and residue management of either soybean (SR) and/or wheat (WR) on yield performance and soil physico-chemical properties. The experiment was laid out in randomized block desi...
this experiment was conducted to investigate the effects of using three commercial enzymes on performance and carcass quality of broiler chickens fed with wheat-barley-soy based diets. in a completely randomized design 405 of broiler (ross308) in nine treatments, three replicates (with 15 bird in each replicate) were used. the experimental diets included 1) diet based on corn–soybean meal (with...
Soybean is the most important legume crop in the world. Several diseases in soybean lead to serious yield losses in major soybean-producing countries. Moreover, soybean can be infected by diverse viruses. Recently, we carried out a large-scale screening to identify viruses infecting soybean using available soybean transcriptome data. Of the screened transcriptomes, a soybean transcriptome for s...
Shortly after its arrival, the soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), became established as the most important insect pest of soybean, Glycine max L. (Merr.), in the northern part of the North American soybean production region. Soybean resistance is an environmentally sustainable method to manage the pest and new soybean aphid resistant cultivars are beginning to be de...
The objective of this paper is to investigate the impacts of implementation of the FTAA and China’s lower import tariffs on international trade of soybean oil, soybean meal, and soybeans. A two-commodity spatial model was formulated. The base model was calibrated to simulate the average level data of 1996, 1997, and 1998. Two alternative trade scenarios were simulated. The results indicated tha...
The soybean aphid, Aphis glycines Matsumura, is one of the most important economic pests affecting soybean production in Wisconsin and neighboring states. Since its discovery in 2000, the soybean aphid has become established in the North Central Region and presents a potential threat to the soybean industry. Insecticides are available for control of the soybean aphid, but are an additional prod...
This study was conducted to determine the nutritive value of soybean varieties using in vitro methods and gas production technique.In vitro gas productions and gas production kinetics of soybean variety were determined at 0, 3, 6, 12, 24, 48, 72 and 96 h incubation times. This study revealed that there were variations among five different soybean varieties in terms of chemical...
Soybean (Glycine max [L.] Merr.) establishes a symbiotic relationship by infection with soybeannodulating bacteria and subsequent root nodule formation. Soybean acquires atmospheric nitrogen as ammonia through the symbiotic nitrogen fixation by soybean-nodulating rhizobia in the root nodules. The inoculation of soybean with bradyrhizobia that has high ability of nitrogen fixation is considered ...
Capillary electrophoresis was applied for the first time to determine soybean proteins in commercial soybean products. The most suitable conditions for the analysis of these products in less than 7 min were 0.05 M phosphate buffer (pH 8) with 1 M urea; detection wavelength, 254 nm; applied voltage, 20 kV; and temperature, 30 degrees C. Quantitation of soybean proteins was achieved using referen...
In the north central United States, populations of the exotic soybean aphid, Aphis glycinesMatsumura (Hemiptera: Aphididae), are highly variable across space, complicating effective aphid management. In this study we examined relationships of plant nutrients, landscape structure, andnatural enemieswith soybeanaphid abundance across Iowa,Michigan,Minnesota, andWisconsin, representing the range o...
