Due to the increasing need of the country to imported edible oil and rapeseed importance among oilseeds, efforts to increase its grain yield and oil content are of high importance. Therefore, recognizing the traits that increase grain yield of rapeseed has an important role in the success of breeding programs. Thus, sixteen rapeseed genotypes were evaluated in a randomized complete block design...

The relationship between some important morphological traits with seed yield in 18 soybean genotypes inclusive three cultivars (JK, May and Cap) and 15 M4 mutant lines were investigated using randomized complete block design with four replications. Results of analysis of variance indicated that there were significant differences between genotypes in all traits except the number of branches per ...

there are two major theories of measurement in psychometrics: classical test theory (ctt) and item-response theory (irt). despite its widespread and long use, ctt has a number of shortcomings, which make it problematic to be used for practical and theoretical purposes. irt tries to solve these shortcomings, and provide better and more dependable answers. one of the applications of irt is the as...

In order to evaluate genetic variation and path analysis of yield components and grain yield, 49 soybean genotypes were studied based on simple lattice design. Analysis of variance based on lattice design revealed significant differences among the genotypes for all the traits. The results of path analysis revealed that among yield components, 1000-seed weight showed significant positive direct ...

This experiment was conducted in the Research Farm of the Faculty of Agricultural Sciences, University of Guilan in 2010 as an RCBD based split plot experiment with three replications. In this experiment five different amounts of soil moisture (Irrigation after depletion of 45, 55, 65, 75 and 85% of field capacity moisture) and two soybean cultivars (Gorgan-3 and Williams) was considered as mai...

     Due to evaluation Yield and Its components and determining the most important treats affecting on the Yield, 12 different accessions of sesame were cultivated under both normal irrigation and drought stress by randomized complete block design with three replications at Research Farm of Birjand in 2012-2013 years. The parameters measured included the number of capsules, plant height, number...
