the effect of irrigation disruption in different reproductive growth stages on yield, yield components and oil content in three spring safflower cultivars
oil has an important role in human food. an experiment was conducted in order to evaluate the response of spring genotypes of safflower to irrigation disruption in reproductive growth different stages, in a spilt plot arrangement based on randomized complete block design with four replications at research farm, faculty of agriculture, university of birjand during 2008. irrigation regimes (full irrigation = whole season irrigation, irrigation until grain filling, irrigation until flowering, and irrigation until heading-bud) and cultivars (mahali isfahan (a local variety), isfahan28 and il111) were arranged in main plots and subplots, respectively. results showed that irrigation until heading-bud stage caused a significant reduction in number of total and fertile head per plant, number of seeds per head, 1000-seed weight, seed yield and oil content and yield. among cultivars, mahali isfahan had the most number of total and fertile head per plant and number of seeds per head and il111 showed just the reverse response. also between yield components, number of total head per plant showed the highest correlation with yield. according to the results, mahali isfahan variety in all of the irrigation disruption regimes produced the highest kernel yield. therefore, due to the nativeness of this cultivar and high adaptation to this arid climatic zone, provide an opportunity for producing higher yields in comparison with other cultivars under water stress.
effect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Effect of irrigation cut at different stages of growth on yield, yield components and grain quality of different cultivars of sorghum seeds
In order to investigate the effect of water deficit tension on different growth stages on yield, yield components and produced grain quality of sorghum seeds cultivars, an experiments was performed as split plots based on randomized complete blocks design with four replications in Isfahan Ghiam Cultivation and Cattle Farm Company in 2017. The main factor including irrigation cut at four levels...متن کامل
