this study was performed in order to evaluate the effects of drought stress and nitrogen fertilizer on phenology, morphology and yield of four cultivars of chickpea. this experiment was performed in a split-factorial using randomized complete block design with three replications. drought stress treatment stood in main plots (in three levels) consisting of no drought stress (control), moderate d...

to evaluate the effect of various levels of nitrogen fertilizer on nitrogen use efficiency and grain yield of canola cultivars, a split plot experiment based on randomized complete block design was conducted in 2007. factors were: nitrogen fertilizer at four levels (zero, 50, 100 and 150 kg/ha) in the main plots and canola cultivars at three levels (‘clover’, ‘opera’ and ‘okape’) in the sub plo...

Fertigation is widely used in the new intensive olive orchards, although, there is not enough information for a rational management of this practice. Preliminary results of an fertigation experiment iniciated in 1999 in a mature olive orchard of the cultivar ‘Manzanilla de Sevilla’ are presented. Four treatments were established: T1(no fertilizer) and T2, T3 and T4, in which the trees received ...

in order to investigate the effect of phosphorus fertilizer and spraying fe chellat in micronutrients absorption rate, rate of proline and soluble carbohydrates in bread wheat and some of its ancestral species in dryland condition, a factorial experiment was conducted with three factors consist of: p fertilizer (in two levels), spraying fe chellat (in two levels) and different species of wheat ...

in this research for study the effects of nitrogen fertilizer on yield and yield components of current rice cultivars was an experiment as factorial in rcbd with three replications where conducted during 2009 year in two locations (rice research institute, rasht, and rudsar, east of guilan). factors were cultivars (khazar, ali kazemi and hashemi), and nitrogen fertilizer levels (0, 30, 60, and ...
