Littele is known about the relationships of different traits in safflower using wild and cultivated species. In this study, 46 safflower genotypes from five different species were evaluated under normal and deficit irrigation and the relationship of traits was assessed. Results showed that water stress had significant effect on head yield per plant, number of seeds per head, head diameter and 1...
Due to increasing water and growing demand for food 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 condition...
In order to investigate the effects of sowing date (SD) and single irrigation (SI) amounts on yield and yield components of rainfed wheat varieties, a field experiment was conducted as split-split plots arranged in a randomized complete blocks design with three replications during 2002-2004 at main station of Dryland Agricultural Research Institute in Maragheh, Iran. Treatments included three s...
water deficit is an important factor limiting crop growth all over the world. in order to evaluate genetic variation, heritability and the interrelationship between agronomic traits, twenty chickpea genotypes were cultivated in two separated randomized complete block experiments with three replications under normal irrigated and rainfed conditions. the experiments were carried out at the agricu...
in order to evaluate the effect of balanced application of chemical phosphorus fertilizer and seed inoculation with phosphate solubilizing bacterium and arbuscular mycorrhizal fungus and on the yield and yield components of maize (zea mays l.) under normal and limited irrigation conditions, a split-split plots arrangement based on randomized complete block design with three replications was con...
Supplementary irrigation is one of the most effective field management practices to improve water productivity and crop yield in rainfed conditions. Time of supplementary irrigation is another important parameter affecting the enhancement of yield. In order to study the effect of supplementary irrigation time as well as planting date, two factors, namely: 1) supplementary irrigation (No irrigat...
The effects of potassium fertilizer (K2SO4) levels K0, (0), K1,(150) and K2,(250 kg/ha) in two species of Brassica napus (Hyola 401 Hybrid) and Brassica juncea (landrace cultivar), under three irrigation regimes, control (irrigation after 50%,), moderate stress, (irrigation after 70%), and severe stress (irrigation after 90% soil water depletion) were studied in a factorial experiment laid out ...
a split plot experiment based on complete block design with three replications was carried out to evaluate the effect of irrigation and potassium fertilizer on yield and yield components of green beans, in 2011 at ahvaz. two levels of irrigation (normal irrigation and drought) and four levels of potassium sulfate fertilizer (0, 25, 50 and 100 kg ha-1) were evaluated in this study. the results o...
In order to study the effects of supplementary irrigation and nano iron oxide on the grain yield, and some physiological and biochemical traits of wheat (Triticum aestivum L.) under rain fed conditions, a factorial experiment was conducted based on a randomized complete block design with three replications in Agricultural Research Station of Ardabil, Northwest of Iran, in 2016. Factors inclu...
to study the effect of sowing date and supplemental irrigation on grain yield and distribution and remobilization of phosphorus in canola (brassica napus), this experiment was carried out in 2 years (2005-07) in research station of gonbad. the study was carried out in two types of irrigation treatments (rainfed, supplemental). both experiments were carried out in randomized complete block desig...
