an experiment was conducted as a split – split plot in form of a randomized block design with four replications in cilakhor region of iran in 2004. the main factor was the seed planting date with three levels (5, 12 and 25 april), sub factor was the crop density with two levels (160,000 and 250,000 pl/ha) and sub-sub factor was the crop arrangement with two levels (equidistant and non-equidista...

to study the effect of plant density on seed yield and yield components of two lentil cultivars a field experiment using factorial design based on a complete block design was conducted with three replications at research farm of college of agriculture and natural resources, university of tehran (karaj) in 2008. treatments were lentil varieties (ziba, mardom), and plant densities (80, 160, 240, ...

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 study the effect of different nitrogen levels on yield components and seed yield of three barley cultivars, an experiment was conducted in 2011-2012 in a research farm of farming building of islamic azad university khorasgan (isfahan) branch located in khatunabad village (latitude 32o /40' n and longitude 51o /48' e). a split plot layout within randomized complete block design wit...

drought stress is considered as the most important environmental abiotic stress, affecting grain yield of crop plants especially in arid and semi arid regions. increasing and utilization of the genetic diversity can be a useful strategy in breeding for drought resistance. in this study, twenty iranian durum wheat landraces along with two check cultivars were evaluated in a randomized complete b...

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...
