According to urgent need of corn to nitrogen and since this element play a main role in improving of yield corn, thus, in order to investigate the effect of different levels of urea on yield and yield components of corn 704, an experiment was conducted randomized block with three replications in cropping year of 2012. Experimental treatments included six levels of urea (0, 30, 60, 90, 120 and 1...

In order to study the influence of compost and biofertilizer on yield and essential oil of dill (Anethum graveolens L.), an experiment was conducted as factorial experiment in the base of randomized complete blocks design with eight treatments and three replications at research field of Agriculture Company of Ran in Firouzkuh of Iran in 2012. The factors were compost in four levels (0,...

in order to evaluate the effects of beneficial free living bacteria (azotobacter chroococcum and azospirillum brasilense) compared to different nitrogen fertilizer levels on yield and yield components of barley (hordeum vulgare cv reyhan) a field experiment was conducted at research station college of agriculture, ferdowsi university of mashhad in 2007-2008. the experiment was arranged in a ran...

drought stress is one of the most important abiotic stresses which can affect the growth of a plant, thereby curbing crop yield. identification of effective morphological traits is the main aim of each breeding program. our objective was to identify agronomic traits associated with changes in grain yield of wheat under irrigated and drought conditions. to address this objective, grain yield and...

The experiment was investigated to survey of yield and yield components of sunflower cultivars under drought stress in 2012 in Kabootatabad of Esfahan farm. An experiment was conducted in split plot and was designed in randomized complete block with three replications. Irrigation was as main plots in 3 levels (control (normal irrigation), irrigation of 130 mm evaporation from pan evaporation, i...

in order to evaluate of biological fertilizers and micronutrient elements effects on yield and some agronomic traits in rapeseed (brassica napus l.), an experimental was performed as factorial arrengement based on randomized complete blocks design with three replications in 2012-13 in research station of shahid chamran university of ahvaz, iran. in this experiment, micronutrient elements were i...

in order to study the density and diversity of weeds and yield of barley and hairy vetch affected by mixed intercropping ratios, a field experiment was performed based on a randomized complete block design with four replications at the agricultural research station, college of agriculture, ferdowsi university of mashhad during growing season of 2012-2013. ratios of mixed intercropping were 75% ...
