We investigated if elevated CO(2) could alleviate the negative effect of high temperature on fruit yield of strawberry (Fragaria × ananassa Duch. cv. Toyonoka) at different levels of nitrogen and also tested the combined effects of CO(2), temperature and nitrogen on fruit quality of plants cultivated in controlled growth chambers. Results show that elevated CO(2) and high temperature caused a f...

The effects of Range Management Plans (RMP) on soil and vegetationcharacteristics were studied in Eshtehard rangelands at Alborz province. The parameters ofyield, canopy cover, range condition and trend, bulk density, Organic Matter (OM%),Nitrogen (N), Phosphorous (P) and Potassium (K) were estimated on soil samples in sitesof Ghenzel Cheshmeh as RMP and sanctum of Rahmanyeh village. The data w...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
Nine multiparous lactating cows averaging 171 days in milk were divided according to days in milk and milk production into three 3×3 Latin squares with three 3-week periods to investigate the effect of rumen degradable protein on milk urea nitrogen. Diets were formulated to provide 3 concentrations of dietary rumen degradable protein (9.8, 10.8, and 11.8% of dry matter), while rumen undegradabl...
this research has been done for studying the effect of split application of nitrogen fertilizer on growth indexes and yield of three hybrids of grain corn in shahrood. a split plot experiment based on randomized complete block design with four replications was carried out in 2007. three hybrids of corn (double cross 370, single cross 447, single cross 499) were placed in main plots and split ap...
This research was conducted to investigate the effect of growth-promoting bacteria on yield and some traits of maize. This experiment was performed as a factorial randomized complete block design with three replications at research farm of Islamic Azad University, Izeh branch, Iran. The experimental factors included four strains of plant growth-promoting bacteria: Pseudomonas fluorescent 169 (B...
in order to study the effects of plant density and nitrogen rates on yield, nitrate and protein of silage maize (ksc 704) in shahrekord area, an experiment was conducted during 2007 growing season at the agricultural research farm of shahrekord university. the experimental design of the experiment was randomized complete blocks with factorial arrangement with four replications. treatment consis...
