In order to evaluate relations between phonological trains , yield components and grain yield of 30 soybean lines with different maturity groups , an experiment conducted as a randomized complete block design with three replications at the agricultural research station of agriculture and natural resources research center, Gorgan, Golestan Province in 1388. 13 traits of vegetative and reproduct...

In order to evaluate the productivity of 20 bread wheat promising lines using multivariate statistical methods, an experiment was conducted based on a randomize complete block design under terminal moisture stress, in 2011-2012. Factor analysis showed that the three first factors explained 66% of total variance. Plant height, peduncle length, 1000 kernel weight, harvest index, biological yield,...

To determine the relationships between agronomic and physiological characteristics of soybean, 30 soybean genotypes in factorial experiment based on a randomized complete block design were planted in Sari of Agricultural Sciences and Natural Resources University (SANRU). Correlation coefficients between traits showed positive and significant correlation between the considered traits and grain y...

     To improve a complex characters such as grain yield with low heritability, indirect selection through other characters and selection index based on different effective traits were used. For this purpose, 96 F3 families derived from Roshan and Kavir crossing, together with parents, F1 and F2 progenies were cultivated. In lattice design with 2 replications under drought stress conditions in ...

In order to assessment of relationships between effective traits on grain yield and also determination of cause and effect relationships between of them, 121 native and exotic cultivars available in the collection of Rice Research Institute of Iran were evaluated in a simple lattice design (11×11) with two replications for 12 important agronomic traits. The results of analysis of variance showe...

Rice is one of the high water consuming crops and it is important to utilize methods in its production to promote water use efficiency. In order to achieve this purpose, a split plot experiment was conducted in direct-seeding of rice in Kazerun region of Fars province, Iran, in 2007. Five irrigation treatments (full-season flooding, full-season alternating, flooding until tillering stage, flood...

In order to study the response of morphology, yield and yield components of spring safflower (Carthamus tinctorious L.) cultivars to different sowing dates, an experiment was carried out using a split-plot design on the basis of a randomized complete block design with four replications, in Agricultural Sciences and Natural Resources University of Khouzestan, south-west of Iran at 2016-2017. Exp...
