in order to evaluate the relationship between grain yield and agronomic characteristics in bread wheat genotypes in different planting dates under rainfed conditions, a factorial experiment was conducted based on rcbd with four replications at gonbad-e qabus region, iran, during 2012-2014 growing seasons. number of spikes per unit area, grain filling rate, effective grain filling period, number...

One of the technology options that can help farmers cope with water scarcity at the field level is alternate wetting and drying (AWD). Limited information is available on the varietal responses to nitrogen, AWD, and their interactions. Field experiments were conducted at the International Rice Research Institute (IRRI) farm in 2009 dry season (DS), 2009 wet season (WS), and 2010 DS to determine...

Anethum graveolens Linn. (Umbelliferae, A. graveolens) is a widely used spice with a long history of traditional medicinal use for the treatment of various ailments. The biosynthesis of secondary metabolites in medicinal and aromatic plants is affected by abiotic stresses such as water deficit. This study was carried out to evaluate seed yield and essential oil of dill under five irrigation dis...

water deficient is one of the most important limiting factors in rapeseed (brassica napus l.) production in arid and semiarid areas speciallyiran, which is the best approach to deal with the introduction of resistant and compatible varieties to drought stress. the response of fourteen rapeseed cultivars to water stress was studied in a split plot experiment based on complete randomized block de...

Current study was carried out to assessment the effects of zeolite on seed yield, physiological and biochemical traits of sorghum in response to different irrigation regime according split plot arrangement based on complete randomized block design with three replications in Varamin region (Central of Iran). The main plots consisted of different irrigation regime at four levels [Normal irrigatio...
