in order to study of some effective phenologic and physiologic characteristics on 18 sunflower hybrids yield under optimum conditions, an experiment was conducted as randomized complete block design with three replications at the research field of seed and plant improvement institute-karaj in 2006-2007. the result indicated that the hybrids showed significant difference in phonologic characteri...

common vetch ) vicia sativa .l) is belong to fabaceae family and due to adaptation and tolerance to environmental stresses are considered. in this research, morphological and agronomic characteristics of 89 genotypes of common vetch ) vicia sativa .l) were evaluated in an augmented design under irrigated and drought stress conditions in research field of university of tehran at karaj in 2011. r...

in order to evaluate the effects of drought stress and methanol foliar application on some quantitative and qualitative traits of soybean (cv. viliamz), a split plot experiment was conducted based on randomized complete block design at the faculty of moghan research farm in 2011. treatments were three levels of drought stress based on irrigation at depletion of 40, 55 and 70 percent of availabl...

grass pea (lathyrus sativus l.) has a high potential for forage production inboth rangelands and cultivated rainfed areas of iran. it is well adapted to semi-arid areas ofwest and north of country where annual rainfall is 250–350 mm. to study the seed and drymatter (dm) yield and agronomic traits, six genotypes of lathyrus sativus l. and twogenotypes of lathyrus inconspicuous l. were provided b...

in order to identify drought stress tolerance in rapeseed, nine commercial rapeseed cultivars (opera, karaj1, karaj2, karaj3, zarfam, okapi, talayeh, licord and modena) were evaluated under two conditions (normal and drought stress) in kangavar region in the west iran in 2014-2015 growing season. this research was carried out in a split plot experiment based on completely randomized design in f...

research on crop response to deficit irrigation is important to reduce agriculture water use in areas where water is limited resource. using drought resistant landraces with irrigation scheduling based on phenological stages in semi-arid and arid regions may provide an opportunity to optimize irrigation efficiency and water savings in these regions. in order to evaluate of yield and yield compo...

Objective: In order to study the effect of solopotasse fertilizer on yield and essential oil of cumin medicinal plant. Methods: A experiment in randomized complete block design with three replications conducted in kermam city, Iran, in 2013. solopotasse fertilizer in four levels (0, 50, 100 and 150 kg/h) investigated. Plant height, number of umbrella per plant, number of seed per umbrella, 1000...
