Within the last years a lot of effort has been made to improve irrigation efficiency and early drought stress detection by using various remote sensing techniques. In the present study two different species of wheat (Triticum aestivum and Triticum durum), cultivated in a growth chamber, were used to investigate the effects of drought occurring at different phenological stages. Plant physiologic...

this study was carried out in order to identify the effects of soil water depletion (swd) on monogerm sugar beet (cv. shirin) seed growth trend at different growth stages. an experiment was conducted in randomized complete block design (rcbd) with three replications in ardebil agricultural research station. during 2002 and 2003 cropping seasons, nine treatments including control (irrigation aft...

Remobilisation of non-structural carbohydrates (NSC) from leaves and stems and unloading into developing grains are essential for yield formation of rice. In present study, three recombinant inbred lines of rice, R91, R156 and R201 have been tested for source-flow-sink related attributes determining the nature of NSC accumulation and translocation at two nitrogen levels in the field. Compared t...

this research has been done for studying the effect of split application of nitrogen fertilizer on growth indexes and yield of three hybrids of grain corn in shahrood. a split plot experiment based on randomized complete block design with four replications was carried out in 2007. three hybrids of corn (double cross 370, single cross 447, single cross 499) were placed in main plots and split ap...

in order to study the role of photosynthetic tissues on grain filling and remobilization of stem reserves under terminal drought, a pot experiment as semi-field was conducted as two-factor factorial in complete randomized design with three replicates at research farm of agriculture college of vali – e – asr university of rafsanjan during january to june 2012 . first factor was source strength r...

an experiment was carried out in 2008 to investigate the effects of different irrigation regimes, and chickpea cultivars on chickpea production in the khorramabad lorestan. the experiment was split–plot in a randomized complete block design with 3 replications. supplementary irrigation at 8 levels (1-rainfed without irrigation, 2-irrigation after sowing, 3-irrigation at flowering, 4-irrigation ...
