introduction safflower is native to iran, and is cultivated for high adaptability, low water requirement, resistance to drought and useful unsaturated fatty acid (ashri et al., 1977). identification of effective agronomic traits and relationship between them are important aims under water stress conditions. among these characters, grain yield is the most important trait that is genetically poly...

objective: field experiment was conducted in 2009 to investigate the effects of plant density and weed interference on morphological characteristics and yield of corn (zea mays, l.) at research station of university of tabriz, tabriz, iran. methods: the experiment was arranged as split plot based on randomized complete block design with three replications. plant density (d1, d2, d3 and d4: 5, 7...

the main objective of this study was to understand of genetic association between quantitative and qualitative traits and also to quantify effects of selection for one trait on others in safflower. the study took place in the experimental field of the faculty of agriculture, isfahan university of technology, isfahan, iran, in the 2001 and 2002. to find the best variable for selection to improve...

in order to investigate effect of deficit irrigation on phenological stages and yield of soybean cultivars, an experiment was conducted as split plots based on randomized complete block design with three replications at agricultural research farm, university of guilan in 2009. main factor was included four irrigation levels based on potential moisture 30-35 (i1), 50-55 (i2), 70-75 (i3) centibar...

this study was performed in order to evaluate the effects of drought stress and nitrogen fertilizer on phenology, morphology and yield of four cultivars of chickpea. this experiment was performed in a split-factorial using randomized complete block design with three replications. drought stress treatment stood in main plots (in three levels) consisting of no drought stress (control), moderate d...
