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...

Agricultural nonpoint source pollution is the main source of nitrogen (N) and phosphorus (P) in the intensely row-cropped Upper Mississippi River Basin (UMRB) stream system and is considered the primary cause of the northern Gulf of Mexico hypoxic zone according to the US Environmental Protection Agency. A point of crucial importance in this region is therefore how intensive corn (Zea mays L.)-...

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...

The continuous growth of irrigated agricultural has resulted in decline groundwater levels many regions Maryland and the Mid–Atlantic. main objective this study was to use crop water productivity as an index evaluate different irrigation strategies including rainfed, groundwater, recycled use. Soil Water Assessment Tool (SWAT) used simulate watershed hydrology yield. It estimate corn soybean us...

ABSTRACT Seed treatment is an important procedure in soybean cultivation and currently performed two ways: industrial seed (IST), by the companies industry, OnFarm treatment, performedby producer. The objective of this research was to compare influence technologies, including machines processes, on occurrence mechanical damage functional quality treatment. Soybean seeds were subjected phytosani...

Flowering is an important agronomic trait that determines crop yield. Soybean is a major oilseed legume crop used for human and animal feed. Legumes have unique vegetative and floral complexities. Our understanding of the molecular basis of flower initiation and development in legumes is limited. Here, we address this by using a computational approach to examine flowering regulatory genes in th...
