Three levels of urea (0, 0.5 and 0.75% on fresh weight basis) were added to whole corn plants to investigate their effects on the chemical composition, and digestibility in 16 Ghezel male lambs using a completely randomized design. Rumen degradability and nutritive values were also evaluated. pH, total nitrogen and ammonia-N concentration of silages increased (P<0.05) with the addition of urea....

This experiment was carried out to study the effects of Lactic Acid Bacteria (LAB) and urea on chemical composition, nutritive value and rumen fermentation characteristics of whole-crop barley. In a completely randomized design with cross over arrangement, 4 Suffolk male lambs were used. Whole-crop barley was either treated with LAB solution (35% dry matter) at the rate of 2 L/ton herbage fresh...

Drought stress has an important role in yield reduction of crops. To investigate the effects of applying zeolite hydrogel (as a superabsorbent) in reduction of adverse effects of drought stress on chlorophyll content, nitrogen, growth indices and their relationships with quantitative and qualitative yield of pearl millet (cv. Nitrifeed), a split plot experiment (in space and time), based on ran...

Genetic diversity is the base of plant breeding. Hence, 33 M7 soybean mutant lines, which were evolved by γ ray from cultivar L17 irradiated with doses of 150, 200 and 250 Gray (absorbed dose), with L17 cultivar and two commercial cultivars (Clark and Williams) were evaluated in view of some morphological traits (number of leaves/plant, pods/plant, seeds/pod, seeds/plant, 100-seed weight, dry w...
