in order to deliberate correlation coefficient between grain yield and yield components among 31 cowpea genotypes under normal irrigation (non-stress) and drought stress (water withholidng after flowering stage until maturity) an experiment was performed in a randomized complete block design (rcbd) with three replications at research field of university of tehran located at karaj during 2011-20...

cumin (cuminum cyminum l.) is one of the most important cultivable medicinal plants in iran and today, it is the second most popular spice in the world after black pepper. it is essential to know the relationships between yield and its components in cumin breeding programs. therefore, different multivariate statistical analysis was performed on plant characters in cumin to determine the relatio...

the dragon's head(lallemantia iberica f. & c. m.) can be introduced as a new oilseed crop to cold rainfed areas because of its unique characteristics. the field trial was carried in a split-plot factorial in a randomized complete block design (rcbd) with three replications in dryland agricultural research institute (dari) in 2010-11. the treatments included three landraces of dragon’s head...

Thirty advanced breeding lines of deep-water rice were evaluated during T. Aman season (rainfed ecosystem) with a view to finding out variability and genetic association for grain yield and its component characters. All the tested characters showed significant variation. The highest genetic variability was obtained in filled grains/panicle followed by plant height. Panicles/plant, filled grains...

this study was conducted to evaluate the effect of fertilizers on the yield and essential oils of basil. this experiment was carried out in completely randomized block design with three replications in jiroft area. the treatments included three levels of barvar 2 (10, 20 and 25 g/ha), cow manure at three levels (5, 10 and 15 ton/ha), ammonium phosphate and superphosphate triple each at three le...

the aim of this study was evaluation of some of characters, estimation of their heritability and their relationship in 104 recombinant inbred lines population of durum wheat under pot and field conditions. the inbred lines, their parents and control genotypes were evaluated in completely randomized design in 3 replications at pot study and in augment design at field condition. analysis of varia...
