Rotation, tillage, and variety main effects on grain yield were all significant in 2002. Rice grain yield, over all treatment combinations, averaged 159 bu/acre, which was 22 bu/acre more than in 2001. Grain yields for the two 3-phase rotations were 180 bu/acre for the rice-corn-soybeans rotation and 177 bu/acre for the rice-corn (wheat)soybean rotation. These yields were slightly better than t...

Drought is one of the major problems affecting crops production, including corn, in many parts of Iran. In order to detect drought tolerant grain corn hybrids, an experiment with twenty corn hybrids was conducted during 2006 in Qom Province, Iran, using a complete randomized block design with four replications, under optimal moisture and drought stress condition. Results showed diversity among ...

Lectins extracted from corn (Zea mays L.) kernel with Tris-HCl buffer pH 7.5 were isolated from the crude extract by affinity chromatography on Sepharose 6B-N-acetyl-d-galactosamine and Sepharose 6B-methylalpha-d-mannoside, and also by lectin affinity chromatography using concanavalin A and Lens culinaris lectin as ligands. According to preferential monosaccharide specificity, salt-soluble lect...

In a survey conducted in 1984 in Essex, Lambton, and Middlesex Counties of Ontario, Canada, greater incidences of head blight and greater concentrations of deoxynivalenol in grain were observed in fields of winter wheat planted after corn than in those planted after soybeans, barley, and mixed grains. Neither head blight nor deoxynivalenol level were correlated significantly with soil P, K, or ...

Distillers dried grains with solubles (DDGS), a co-product of the dry-mill ethanol industry, are the dried residue that remains after the fermentation of corn (or other grains) mash by selected yeasts and enzymes to produce ethanol and carbon dioxide. The nutrient composition of DDGS varies depending on the source of grain and the methods used for ethanol and DDGS production. Generally, corn DD...

For many years, N recommendations in the Midwest were based on achieving a specific corn yield goal (if you want so many bushels per acre, apply so much N). This began to change in 2006 when several universities in the Corn Belt adopted a substantially different N recommendation system. That system was developed from recent N trial results and took into account the relative costs of grain and N...

exiting diversity is the basis of selection in plant breeding programs. diversity in morphological traits is studied by different methods of multivariate analysis. this study was conducted to estimate the genetical diversity of new corn hybrids based on the morphological traits. in this study, 40 new grain and forage corn hybrids with five commercial varieties as control treatments were planted...
