In order to evaluate the effect of different rates of nitrogen (N) and corn, rapeseed, sunflower and wheat residues on plant height, biological and grain yield and N use efficiency of wheat, an experiment was conductedduring 2010-2011 at Agricultural College of Shiraz University. The experimental design was split-split plot based on RCBD with four replications. Treatments were N (45, 90, 135 an...

In order to investigate the effects of drought stress on grain yield and its components, a study was carried out (2011) as split plots in randomized complete blocks design in Isfahan (32° 40'  N,51° 48' E). Main factor was drought stress in four levels including irrigation after 80, 100, 120, and 140 mm evaporation from evaporation pan (class A) and subplots were three cultivars (Sirena, Record...

To compare the yield and yield components of 10 promising dryland barley genotypes with a conventional cultivar (Reihan03), a field experiment was conducted based on a randomized complete block design in Miyaneh region in the 2010-2011 growing season, and their agronomic and morphological traits were recorded. Genotypes were significantly different in terms of all the studied traits, and genoty...

Drought stress is the most important factor restricting both growth and crop yield formation under arid and semi-arid conditions. In a field experiment, the effects of foliar application of growth regulators of auxin at three levels (0, 20 and 40 mg/L) and cytokinin at three levels (0, 50 and 70 µmol) at pollination stage on yield and yield components of a bread wheat (Shiraz cultivar) and duru...

In order to study the effect of salicylic acid and selenium foliar application on physiological characteristics, yield and yield components of safflower (Carthamus tictorius L.) under drought stress conditions, an experiment was conducted as split plot based on randomized complete block design with three replications. The main factor included irrigation in three levels, complete irrigation duri...

A more efficient water use system is needed for agriculture. This is more evidence for rice production with a higher water use for economical production. A large cultivar×water regime interaction exists for grain yield in rice. Therefore, information is required to adopt new rice cultivars with high yield potential under water-saving conditions. The objectives of this study were to analyze the ...
