In order  to study the effect of drought stress on some growth indices of oil sunflower cultivars, a study was conducted in Isfahan. The experiment was conducted as split plots in a randomized complete blocks design with three replications in Isfahan (51° 48' E, 32° 40' N).Main plots were drought stress in four levels (80, 100, 120, and 140 mm evaporation from evaporation pan class A and cultiv...

in order to determine the optimum sowing and harvesting dates of two autumn sugar beet cultivars (bete vulgaris l.) and develop the planting area of this crop, the present research was conducted in fasa, iran during 2005-2008. the experiment was carried out in split-split plots based on randomized complete block design (rcbd) with four replications. three sowing dates (september 27, october 17 ...

concinciding of wheat growth in post-anthesis period by water deficiency can result in reduction of current photosynthesis. in this circumstance stem-stored carbohydrate from pre-anthesis period had an important role in supporting assimilates for growing grain. an experiment was conducted in 2007-8 in experimental farm of arsanjan islamic azad university, in order to investigation the quantity ...

application of various composts has been intensified in agriculture, due to manifestation of negative effects of chemical fertilizers on environment and soil fertility. however, their usage should be accompanied by environmental and nutritional studies. to study the effects of sulfur granular compost on yield and yield components of two wheat cultivars, a pot experiment was conducted in a compl...

the effect of different fertilizing systems and drought stress during grain development on grain minerals of barley (hordeum vulgare l.) was studied in field experiments on a clay-loamy soil during 2007 and 2008 growing seasons. the treatments consisted of three irrigation regimes (main plots) of: non-stressed (ns, normal irrigation continued until the end of plant physiological maturity), ...

in order to evaluate the effects of different organic and chemical fertilizers on yield, yield components and seed oil content of sesame an experiment was conducted in a split plot layout based on randomized complete block design with four replications at research station, faculty of agriculture, ferdowsi university of mashhad in year 2006. four types of fertilizer, including chemical fertilize...

The process of vernalization is mainly controlled by two genes in winter barley (Hordeum vulgare L.), VRNH1 and VRNH2. A recessive allele at VRNH1 and a dominant allele at VRNH2 must be present to induce a vernalization requirement. In addition, this process is usually associated with greater low-temperature tolerance. Spanish barleys originated in areas with mild winters and display a reduced ...
