recently, biological fertilizers extensively recommended because of over application of chemical fertilizer and their effects on environment and production resources. in order to study the effect of inoculate phosphate solubilization microorganisms (psm) and plant growth promoting rhizobacteria (pgpr) on nutrient use efficiency in corn [zea mays (l.) cv. sc 604] an experiment was conducted in 2...

in order to study the effect of irrigation and nitrogen fertilizer levels on yield of basil, an experiment was conducted as split plot based on randomized complete block design with three replications in birjand (moud region) in 2010. main plot factor was two irrigation levels (7 and 14 days interval) and nitrogen fertilizer (as urea) was considered as sub plot factor in four levels (0, 50, 100...

in order to study the effect of nitrogen level on physiological characteristics, grain yield and yield components of tetraploid wheat genotypes, a split plot randomized complete block design field experiment with three replications was conducted in 2007 at research farm of isfahan university of technology. four levels of nitrogen fertilizer (20, 80, 140 and 200 kg/ha) were chosen as main plots ...

to study the effect of sowing date and a single irrigation (si) on yield and yield components of barley, a field experiment was conducted in dryland agricultural research institute (maragheh, iran) in 2004-06 cropping seasons, using a split plot based on a randomized complete block design with 3 replications. main plots were assigned to 3 levels of sowing date (early, normal and late). sub-plot...

introduction cultivated sunflower is one of the largest oilseed crops in the world. sunflower seed is the third largest source of vegetable oil worldwide, following soybean and canola. nitrogen is one of the most important elements for crops to achieve optimum yields and quality. phosphorus (p), next to nitrogen, is often the most limiting nutrient for crop and forage production. phosphorus ava...

The experiment was conducted during rabi season from November to January months of 2020–21 in the farm Agricultural Research Station, Utukur, Kadapa, Andhra Pradesh, India study growth and yield performance sesame under different levels times nitrogen application. treatments included four viz., 40, 60, 80 100 kg ha-1 application timings as 50:50 basal 30 DAS, 25:75 25:37.5:37.5 basal, 20 40 DAS...

this study was conducted to evaluate traits that have an effect on yield, and genetic variation for these traits, including dry matter accumulation, remobilization, and traits associated with them, in 10 grain sorghum genotypes obtained from the national plant gene bank of iran under moisture stress conditions. field trials were carried out in the 2008 cropping season using split-plot arrangeme...

this research aimed at investigating the effect of different levels of nitrogen and planting patterns on dry matter production and growth physiological indices in intercropping maize and sunflower. to do this a split plot experiment carried out based randomized complete block design with three replications in research field of shushtar islamic azad university. the main plot included three level...
