Surface energy balance components, including actual evapotranspiration (ET), were measured in a reducedtill maize-soybean field in south central Nebraska during three consecutive non-growing seasons (2006/2007, 2007/2008, and 2008/2009). The relative fractions of the energy balance components were compared across the non-growing seasons, and surface coefficients (Kc) were determined as a ratio ...

Modification of tryptophan side chains of soybean agglutinin (SBA) with N-bromosuccinimide results in a loss of the hemagglutinating and carbohydrate binding activities of the protein. One residue/subunit is probably essential for the binding activity. Modification leads to a large decrease in the fluorescence of the protein accompanied by a blue shift. Iodide ion quenching of the protein fluor...

To date, genetically enhanced plants in the marketplace that are used as feeds for livestock are based on producing insecticidal compounds or developing herbicide tolerance. Corn grain, whole plant green chop corn, corn silage, corn residue, soybeans, and soybean meal from the current genetically enhanced plants have been fed to chickens, sheep, beef cattle, and dairy cows and compared with fee...

A major soybean allergen, Gly m Bd 30K, is a glycoprotein. A peptide containing a sugar chain was isolated from an alpha-chymotrypic hydrolyzate of the allergen. The amino acid sequence analysis of the peptide showed that its sugar chain binds to the Asn170 residue. Furthermore, the sugar moiety of the allergen and peptide was shown to consist of mannose, N-acetylglucosamine, fucose, and xylose...

Recently tillage manufacturers have been promoting vertical tillage systems claiming that their use can overcome production limitations associated with no-till while maintaining sufficient residue cover to provide erosion protection. Vertical tillage refers to systems where soil disturbance is confined to soil movement mostly in the upward direction and/or confined to a slot or strip where the ...

Methods In 2013, ISU FARM conducted two trials in Pottawattamie County that investigated the effect of various tillage systems on soybean grain yield. In Trial 1, a fall vertical tillage system and a fall disking were compared with a no-till system. In Trial 2, a fall vertical tillage system was compared with no-till. Vertical tillage systems are marketed as systems that lightly till the soil w...

containing 30 liters of a medium with agitation rate of 400rpm and air flow of 30 liters/minute. The medium consisted of glucose 2.5%, soybean meal 1.5% dry yeast 0.2% and CaCO3 0.4%; pH was adjusted to 6.2. After fermentation for 90 hours, the culture broth was separated into filtrate and mycelium by centrifugation. The flow diagram for the isolation of I is shown in Fig. 1. The culture filtra...
