in order to study the effect of macro nutrients on growth characteristics of two corn (zea maize l.) varieties (kws2360, ressuda pionee), an experiment was conducted in completely randomized design with three replications at growth room of crop physiology department of debrecen university. the treatments were nutrient solution free nitrogen (n), nutrient solution free phosphorus (p), nutrient s...

Variations in moisture and substrate in preharvest corn kernels and cottonseed were linked with the ability of Aspergillus parasiticus to infect the seed and produce aflatoxin. Osmotic pressures and moisture content (MC) levels of developing starch-rich corn kernels and lipid-rich cottonseed were determined. For in vivo studies, corn kernels and cottonseed were inoculated with A. parasiticus co...

The need for precise and responsive management of N fertilizer in corn production is compelling for both economic and environmental reasons, but the optimum N rate remains an elusive notion. Economically optimal N rates (EONR) in much of North America may range from zero to 225 lb/A (Scharf et al., 2006; Sawyer et al. 2006), and may vary as the growing season progresses (van Es et al., 2007). M...

We evaluated the efficiency of the touchdown method to determine the ideal PCR conditions for distinct inter-simple sequence repeat primers for processing DNA from common corn, popcorn, sweet corn, and a Tripsacum-maize hybrid. Genomic DNA was extracted from eight accessions of corn: two of the dent type, one Tripsacum-maize hybrid, one sweet corn, one flint-type corn, and three popcorn. Fiftee...

This study was conducted under Cumra ecological conditions between 2019 and 2020 in order to determine theperformance of some KWS hybrid corn varieties (V1; Kerbanis, V2; Kefieros, V3; Kontigos, V4; Kefrancos,V5; 2572) belonging different maturity groups. When the results obtained both years wereevaluated together, it seen that highest leaf number, grain protein content, lowest stalk lodgingval...

Two experiments were conducted to evaluate modified wet distillers grains (DGS) as a supplement for roughages. Wet DGS was superior to a mixture of corn and wet DGS as a supplement with tub-ground grass hay for growing steer calves in a 112-d study. Performance of steers fed the grass hay supplemented with DGS or the mixture of corn and DGS was superior to calves fed corn silage. However when D...
