effects of seed priming by salicylic acid on yield and yield components of cowpea (vigna unguiculata) cultivar “parastou” were investigated under water deficit conditions. experiment was carried out as a split block design with three replications in 2008-2009 at research station of zanjan university. factors included drought stress as main factor with three levels (normal irrigation, applicatio...

in order to study the interrelations of photosynthetic rate and surfaces and leaf proline content with yield and yield components of safflower under different irrigation regimes, a field experiment in a split plot arrangement under a ranomized complete block design with four replication was performed at lavark reasrch farm, isfahan university of technology, isfahan, iran in 2007. two irrigation...

ABSTRACT- The crop water stress index (CWSI) is the most common index to monitor and assess crop water stress, based on canopy temperature. To calculate CWSI, upper and lower baselines adaptable to different environments are needed. In this study, empirical and theoretical limiting baseline equations were developed to determine eggplant CWSI values at different levels of water deficit and salin...

experiment was conducted as split plot in a randomized complete block design with three replications in kermanshah to shed lights on economic analysis of deficit irrigation and integrated application of biological and chemical fertilizer son cultivation of medicinal plant borage (borago officinalis l). irrigation tritments include: a) 30% less water than crop requires invegetative, b) inreprodu...

Water deficit is one of the most important difficulties, in which happes in dry zone and half dry zones.Water deficit, as the determinative factor, determinates the growing and extension of the plant cover inthese areas. Using the supper attractive, may reduce the production in the crops and control the plantcover in face of dry stress and water deficit. In this paper, the effect of supper attr...

Development of drought-tolerant cultivars is hampered by a lack of effective selectioncriteria. In this research, response of 36 genotypes of rapeseed from seven species of Brassicaincluding B. napus, B. rapa, B. juncea, B. carinata, B. oleracea, B. nigra and B. fruticulosa wasassessed under three moisture levels (no stress, mild stress and intense stress) in the field during2011-2012. Five dro...

in order to study of deficit irrigation levels on wheat grain yield cultivars based on water productivity indices, an experiment was conducted in a split plot arrangement in randomized complete block design at the field of agricultural and natural resources center of isfahan (kabutarabad research station). three levels of irrigations: 60% of full irrigation (f1) and 80% full irrigation (f2) and...

effects of seed priming by salicylic acid on some morpho-physiologic characteristics and yield of cowpea (vigna unguiculata l.) cultivar “parastou” was investigated under water deficit. experiment was conducted as a split block design with 3 replications in 2008-2009 at research farm of zanjan university. factors were including drought stress as a main factor in 2 levels (irrigation, water defi...
