in order to study the effect of deficit irrigation at reproductive growth stages on growth and grain yield of four sunflower cultivars namely: azargol, allstare, alison and euroflor, an experiment was conducted during the 2007 growing season at the experimental field of the agricultural faculty of bu-ali sina university. the experimental design was a split plot one, based upon a randomized comp...

in order to study the effect of irrigation on fatty acid composition, oil and protein content of sunflower cultivars included azargol, allstar, alison and euroflor, an experiment was conducted at experimental field of the agricultural faculty of bu-ali sina university in 2007. treatments were arranged on split plot based on randomized complete block with three replications. the irrigation treat...

to better understand the potential for improving biomass accumulation and radiation use efficiency (rUE) of winter wheat under deficit irrigation regimes, in 2006–2007 and 2007–2008, an experiment was conducted at the luancheng Experimental Station of Chinese academy of Science to study the effects of deficit irrigation regimes on the photosynthetic active radiation (Par), biomass accumulation,...

Optimum irrigation is very important for nursery stock management of F1-hybrid oil palm (Elaeis guineensis Jacq.), constituting a major production cost. Generally, over watering of nursery stock can be a cause of loss of productivity. The aim of this study was to investigate the physiological and biochemical responses of oil palm nursery stock to reduced soil water content (SWC) and during the ...

to investigate the effects of regulated deficit irrigation (rdi) on the growth, yield and quality of ‘yali’ pears, field experiments for c (fully watered control), ew [early withholding of irrigation, water stress from pullulation to 25 days after flower bloom (dafb)], mw (mid-growth withholding of irrigation, water stress from 25 dafb to 80 dafb), and lw (late withholding of irrigation, water ...

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...

deficit of oil seeds and high volume of oil imports in iran, and limitation of water sources against production of many oil seed crops, demonstrate the importance of detection tolerant species and cultivars for stressful conditions and their most sensitive growth stages to saline stress. in order to study response of spring safflowers (carthamus tinctorius l.) genotypes to disruption irrigation...

This study investigated the interactive effects of different rates of deficit irrigation and timings of N application on wheat and barley yields since there was no report on this important subject. Field experiments in strip-plot designs using sprinkler line sources were conducted for two years at a semi-arid Mediterranean site. The experiments consisted of 4 and 7 irrigation levels with 3 and ...
