Preplant nitrogen (N) application, which involves placing nutrients in the soil before seeding, has been an integral part of crop production systems for decades. Some producers are known to apply N at least 21 d planting. This may increase loss and lower grain yield. study evaluated effect timing rate application on winter wheat (Triticum aestivum L.) yield use efficiency (NUE). An experiment w...

Planting pattern through changing vegetative growth and utilization of environmental resourses affects yield components and seed yield. These effects were studied in the spring of 2000 at the Agricultural Research Station, Isfahan University of Technology, using a randomized complete block design with a split plot layout and three replications. Main plots consisted of three row distances (30 cm...

In order to investigate application of nitrogen rates at different growth stages effects on dry matter remobilization and effective traits at dry matter accumulative of grain in spring barley (Hordeum Vulgare L.), an experiment was conducted as factorial based on randomized complete block design with three replications at the research farm, University of Mohaghegh Ardabili during 2012 cropping....

The pharmacokinetics of trimethoprim-sulfamethoxazole were studied in 12 healthy adult subjects receiving trimethoprim at 20 mg/kg of body weight per day and sulfamethoxazole at 100 mg/kg/day, which is the conventional dose for treating Pneumocystis carinii pneumonia (PCP). Daily doses were evenly divided and orally administered every 6 h for 3 days. Trimethoprim, sulfamethoxazole, and N4-acety...
