One of the main problems of rice cultivation and production is the lack of water resources, especially during periods of low rainfall which affect the vegetative growth rate and the amount of yield. In this study the effect of low water supply on the number of heading per hill, number of grain per hill, dry weight of vegetative tissues and panicle and 1000 grain weight in three new cultivars of...

in order to evaluate some morphological traits of durum wheat genotypes, 18 elite lines selected from advanced regional durum wheat yield trials. these materials along, with two checks dena (durum wheat) and parsi (bread wheat) were examined using rcb design with three replications at isfahan research station in two consecutive cropping season. during the cropping season some trials such as the...
