in order to evaluate the relationship between grain yield and agronomic characteristics in bread wheat genotypes in different planting dates under rainfed conditions, a factorial experiment was conducted based on rcbd with four replications at gonbad-e qabus region, iran, during 2012-2014 growing seasons. number of spikes per unit area, grain filling rate, effective grain filling period, number...
In the sub-tropics, water and nitrogen are the most important factors limiting the grain yield of maize. The effect of nitrogen (N) rates and drought stress at different growth stages of maize were investigated. Nitrogen treatments consisted of 100, 150, and 200 kgN.ha-1 from the urea source while water stress treatments were composed of irrigation-off since the early 10-leaf stage to emergenc...
European agriculture suffers from a substantial deficit of protein sources forlivestock and the projected changes in agro-climatic conditions in Central Europeinclude a higher risk of drought. To address these challenges, the drought resistantlegume crop chickpea was compared with pea, barley and oat regarding its nitrogen(N) yield, protein yield and N use and utilization efficiency under Centr...
In this study, the optimum irrigation depths for corn grain production under different conditions, i.e. maximum grain yield production and maximum benefit under limited land and water conditions, were determined under sprinkler irrigation in Bajgah (15 km. north of Shiraz). The results showed that, the optimum depth of irrigation for maximum grain yield production was 77.0 cm. Because of low pr...
In order to study the effect of drought stress and determination of effective traits on grain yield of wheat in normal and terminal drought stress conditions, 82 wheat genotypes were studied in two separate experiments using randomized complete block design with three replications during cropping season 2011-2012. Drought stress was applied in heading stage by limited irrigation. Set of 22...
Optimum rice population densities and the response of rice yield and yield components to population densities and planting pattern are important factors helping rice producers and researchers to achieve maximum productivity. For this reason, a randomized complete block design experiment was conducted during the summer of 1995 at Isfahan University of Technology Research Farm located at Lavark, ...
Low soil phosphorus (P) availability is a major constraint for crop production in tropical regions. The rice (Oryza sativa) protein kinase, PHOSPHORUS-STARVATION TOLERANCE1 (OsPSTOL1), was previously shown to enhance P acquisition and grain yield in rice under P deficiency. We investigated the role of homologs of OsPSTOL1 in sorghum (Sorghum bicolor) performance under low P. Association mapping...
ارزیابی تجزیه علیت بر روی عملکرد و اجزای عملکرد در برنج (Oryza sativa L.) تحت شرایط نرمال و تنش خشکی
In order to determine the relations between different characteristics with grain yield of rice lines, an experiment carried out with 150 F8 recombinant inbred lines derived from a cross between two Iranian rice varieties Sepidroud (drought susceptible variety, male parent) and Gharib (drought tolerant variety, female parent) along with 6 varieties as check varieties based on Augment design usin...
Wheat grain yield reduction occurs in most wheat growing regions of Iran due to post-anthesis water stress. This research was conducted to evaluate yield and yield components of wheat cultivars in normal irrigation and post anthesis irrigation cut-off conditions as a split-plot arrangement based on a randomized complete block design with three replications during 2015-16 in College of Agricultu...
