in order to evaluate the effects of nitrogen fertilizer on yield, yield components and dry matter remobilization of different rice genotypes, a field experiment was carried out at the farm of ramin agricultural and natural resources university (ahwaz/iran) during 2007. experiment was arranged in a split plot based on randomized complete block design with three replications. four nitrogen fertil...

dry and wet atmospheric depositions as well as urban surface soil samples were collected in eight different land use zones (during 2010) of the most important and largest industrial city, southwest iran for determining cadmium, chromium, lead and zinc. the average of cd, cr, pb and zn concentrations in the study area for wet precipitation were 17.8 μg/l, 49.97 μg/l, 2.31 μg/l, and 0.53 μg/l, re...

A feeding trial was conducted with 870-lb steers fed 137 days to evaluate replacing cracked corn with dry and wet distillers grains with solubles (DGS) as feed for finishing cattle. Dry DGS was evaluated at 16% of diet dry matter. Wet DGS (WDGS) was evaluated at 14.6%, 26.2%, and 37.5% of diet dry matter. Control diets were supplemented with urea or a combination of urea and soybean meal. Feedi...

Fifteen, 1-year-old Populus maximowiczii Henry x P. nigra L. 'MN9' trees were decapitated and allowed to sprout. After 8 weeks, all had 6 to 10 coppice shoots. All shoots, except the tallest (dominant) shoot, were removed from five of the trees (pruned treatment), and shoot growth, gas exchange and carbohydrate status were compared in the pruned and unpruned trees. Although photosynthetic rate ...

Forty-five energy balances were completed with 12 multiparous, lactating Holstein cows in a study designed to determine the energy content of wet corn distillers grains. Treatments were applied in a repeated switchback design and consisted of total mixed diets containing 31.4% corn silage, 18.4% alfalfa hay, and either 30.7% rolled corn and 16.7% soybean meal or 17.0% rolled corn and 31.2% wet ...
