abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
building on previous studies on the effectiveness of different types of written corrective feedback, the present study aimed at investigating whether direct focused corrective feedback and direct unfocused corrective feedback produced any differential effects on the accurate use of english articles by efl learners across two different proficiency levels (low and high). in current study, the par...
This experiment was carried out to investigate the effect of biopolymer coated urea under deficit irrigation on ear yield, nitrogen uptake, nitrogen recovery efficiency and nitrogen use efficiency, grain protein and plant nitrogen content in sweet corn (KSc 403). The experiment was carried out in strip plot arrangement based on randomized complete block design with four replications in Agricult...
In order to study the effects of wild mustard competition and different levels of nitrogen on effective traits of wheat yield, this research was conducted in Ahvaz, south west of Iran. The study was consisted of a split plot experiment, on the basis of Randomized Complete Blocks Design with three replications. Different levels of nitrogen (90, 150 and 210 kgN.ha-1) were assigned in the main plo...
abstract in order to investigate the effects of nitrogen fertilizer levels on the yield and quality of potato, (solanum tuberosum l.) a field experiment was conducted based on randomized complete blocks design with 3 replications in the research field of the college of agriculture, ferdowsi university of mashhad. nitrogen topdress fertilizer was applied in two levels of 100 and 150 kgn.ha-1 and...
this study was conducted under cold temperate climate condition in khorasan during 2006-2008 growing seasons to determine the suitable wheat-based double cropping systems for increase nitrogen agronomic efficiency. a randomized complete block design in split-split plot arrangement with three replicates was used. main plots were crop rotation with five different rotations including wheat:wheat, ...
in order to evaluate the effects of different levels of potassium and nitrogen on nitrogen use efficiency (nue) and yield of rapeseed (hyola 401), a field experiment was conducted at rice research institute of iran (rasht) in a factorial experiment based on a complete randomized block design with 3 replications for two years (2008-2010). the first factor was pure potassium fertilizer in three l...
A field study was conducted at Aboureihan research field of Tehran University in 2009 to find out the effect of nitrogen pellet fertilizer on the grain yield and nitrogen use efficiency of corn (Single Cross 704). The factorial design of the study comprised of randomized complete block with three replications. Factors of this experiment including: first factor was two levels of fertilizer appl...
to assess the effects of different levels of nitrogen and phosphorous on yield and nutrient use efficiency of sugar beet (polygerm seed (cv. 7233)), this study was carried out in 1999-2001 in ardabil agricultural research station (alarough). the experiment contained two factors of: nitrogen in 4 levels (control, 100, 200 and 300 kg n/ha) and phosphorous in 3 levels (control, 100 and 200 kg p2o5...
