drought stress is considered as one of the main important factors reducing field crop yield, thus leading researchers to study the related physiological characteristics may reduce drought effects. this experiment was conducted in research farm of seed and plant improvement institute (spii) in karadj, arak and jolgeh rokh for three cropping seasons (2008-2011) to evaluate drought tolerance of br...

The experiment was conducted to find out the efficacy of dodder vine extract as seed protectant against pulse beetle, Callosobruchus chinensis on gram seed in the laboratory of the Department of Entomology, Bangladesh Agricultural University, Mymensingh during the period of February to May, 2009. The concentrations of dodder vine extract were 5, 2 and 1% respectively. Efficacies of these treatm...

                In order to determine the best developmental stage of three common bean cultivars (Talash, COS16 and Khomain) at which maximum seed quality is attained under different irrigation regimes (I1-irrigation after 60 mm, I2-irrigation after 80 mm and I3-irrigation after 100 mm evaporation from class A pan), a split plot experiment (using R.C.B. design) with 3 replications was conducte...

Bean seed weight and shape are important traits of different market bean classes. One of the first associations found between a genetic marker and a quantitative trait was reported by Sax ( 1923) for the relationship between seed pigmentation {P gene) and seed weight in common bean. More recently three types of molecular markers have been used to study the genetics of seed weight in common bean...

to determine the effect of seed size of sugar beet cultivars on germination and seedling vigor, a study was conducted as a 4×6 factorial experiment based on completely randomized design with 4 replications at seed and plant certification and registration institute, karaj in 2013. the treatments were toucan, dorotea, rasta, sharif, pars, and torbat cultivars and four seed width sizes including 2...

determining general and specific combining ability of lines is necessary to use them as parents of hybrid varieties. in addition, estimates of the heritability of characters helps in selecting suitable breeding methods and predicting genetic gains of the traits. to determine general and specific combining abilities and gene effects of agronomic characters, five cms lines and four restorer lines...

seed purification is one of the important agricultural processes to obtain high quality seeds. using modern technologies help producers to do this process with higher precision and accuracy. in order to separate seed impurities, a separation machine called tribo-aero-electrostatic separator was designed. the machine was evaluated by separating impurities of flixweed (descuriania sophia). primar...

in order to study the effects of different levels of animal manure and bulb weights on growth criteria, yield components, seed yield and essential oil yield of caraway, an experiment was conducted as factorial based on a randomized complete block design with three replications at the agricultural research station, ferdowsi university of mashhad, during two growing seasons of 2012-2013 and 2013-...
