to study the impact of iron nanoparticles foliar application on mitigating the effects of drought stress on yield, yield components and oil percentage of goldasht spring safflower cultivar, an experiment was carried out in 2012 in the agricultural research farm station of islamic azad university, roudehen branch as split plot in a completely randomized blocks design with three replications. in ...

Drought stress is one of the most important abiotic stresses influencing performance of crop plants. Therefore, the identification or development of tolerant genotypes is of high importance for incorporating in cotton production. In this study to evaluate the effect of drought stress on some cotton traits, 5 improved cotton varieties were studied in a split plot design with three replications i...

in order to study the effect of bio-fertilizers  in decrease the effects of water stress on yield, yield components and oil percentage of goldasht spring safflower cultivars (carthamus tinctorius l.), an experiment on split plot in a randomized complete block design with three replications was carried out  in 2012 at the agricultural research station of islamic azad university of roudehen branc...

in order to determine the best time of cotton irrigation in east of mazandaran province, an experiment, conducted for 3 successive years in agricultural research station of baykola. six treatments and four replications were carried out with randomized complete block designs for sahel variety. water treatments were carried out based on, i0: no irrigation, i1: once irrigation in boll opening stag...

In order to study the effect of bio-fertilizers  in decrease the effects of water stress on yield, yield components and oil percentage of Goldasht spring safflower cultivars (Carthamus tinctorius L.), an experiment on split plot in a randomized complete block design with three replications was carried out  in 2012 at the Agricultural Research Station of Islamic Azad University of Roude...

Moisture is a significant component in cotton growth and yield, but stress the main factor limiting crop productivity since it has negative impact on cotton's ability to produce high-quality fiber as well square/boll lint output. Reduced water availability during development of bolls could lead drastically decreased yield. Four genotypes (MNH-1020, FH-114, BH-178 CIM-602) were grown under regul...

due to limited water resources, applying efficient water use in agriculture is very important. this experiment was carried out in kabootarabad agricultural research station for two years using split plots in a randomized complete block design with four replications. six irrigation treatments based on evaporation from class a pan were applied as the main factor at three cotton growing stages, na...

This study was conducted to investigate the effects of soil water deficit on insecticidal protein expression in boll shells of cotton transgenic for a Bt gene. In 2014, Bt cotton cultivars Sikang 1 (a conventional cultivar) and Sikang 3 (a hybrid cultivar) were planted in pots and five soil water content treatments were imposed at peak boll stage: 15% (G1), 35% (G2), 40% (G3), 60% (G4), and 75%...

irrigation water and nitrogen fertilizer are two important factors in increasing the yield and yield components of cotton. in order to evaluate effects of irrigation methods, various levels of water and nitrogen fertilizer on yield and yield components of cotton were studied at hashemabad cotton research station of gorgan in 2008. the experiment was conducted in split-split plots design with th...
