in order to study the effect of nitrogen rate and plant density on morphological traits and essential oil and fruit yield of coriander, a split-plot experiment was carried out in research field of islamic azad university, birjand branch, birjand, iran in 2010 based on a randomized complete block design with three replications. the main plots were nitrogen rates at four levels (0, 40, 80 and 120...

in order to investigate the effects of different levels of nitrogen rate on yield and seed yield components of wheat cultivars, an experiment was conducted on araghi mahalleh (gorogan) research farm in 2008. treatments, nitrogen in the form of urea (0, 90, 180 and 270 kg/ha) and cultivars (tajan, falat and n81-18) were arranged as factorial based on randomized complete block design with four re...

in order to study on the effect of nitrogen, vermicompost and nitroxin biofertilizer on growth indices and phenology of sesame a field experiment was carried out at behbahan in summer of 2009. treatments were arranged in a factorial experiment based on rcbd with three replications. three rates of nitrogen fertilizer (50, 75 and 100% of region recommended nitrogen rate,) as a first factor, three...

a field experiment was conducted in order to study the effect of nitrogen fertilizer and plant density on yield and quality of maize (zea mays l.) cultivar, mv500 silage as second crop. this study was conducted in agricultural research station of kurdistan university during 2012 growing season. the experiment was laid out as split plot based on randomized complete block design with three replic...

abstract this study was conducted under cold climate condition in khorasan during 2006-2008 growing seasons to evaluation of soil fertility in wheat-based double cropping systems under different rate of nitrogen and return of crop residues. a randomized complete block design with split-split plot arrangement and three replicates was used. main plots were five crop rotations namely: wheat-wheat,...
