in order to study the effects of supplemental irrigation and planting arrangement on yield, yield components and water use efficiency (wue) of kabbuli chickpea (cv. arman), an experiment was carried out at the agricultural research station of gonbad for two years, iran. the experiment was a split-plot factorial arranged in a randomized complete block design with three replications. the main plo...
to determine sugar content and root yield variation of new sugar beet hybrids under different irrigation levels, an experiment was carried out at zarghan agricultural research station offars agricultural and natural resources research center, shiraz, iran. the study was conducted as split block based on a randomized complete block design with three replications for two years, 2009-10, using lin...
برآورد وراثتپذیری محتوای روغن و پروتئین دانه در تودههای بومی آفتابگردان آجیلی در سطوح مختلف آبیاری
In order to investigate the genetic diversity and the heritability of oil and protein content of grain in confectionary sunflower under different water availability, 56 local populations were studied in three separate experiments with rectangular lattice design (7×8) with two replications at Agricultural Research Center of West-Azerbaijan province, Urmia, Iran in 2012. Water treatments were wel...
in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
In order to investigate the effect of methanol on the activity of antioxidant enzymes, some compatible osmolytes and biochemical traits of wheat under cut off irrigation conditions, the present experiment as factorial was conducted based on randomized complete blocks design with three replications at the research farm of Faculty of Agriculture and Natural Resources of University of Mohaghegh Ar...
Rice was grown in an open-field Gangetic soil condition with arsenic amended irrigation water in experimental plot at Institute of Environmental Science of Rajshahi University to see the effect of arsenic (As) on growth and yield of rice (Oryza sativa L.). A popular aman rice variety named BR-11 was cultivated with arsenic amended irrigation water (0 mg, 0.1 mg, 0.5 mg, 1.0 mg, 2.0 mg and 4.0 m...
A major challenge in rice (Oryza sativa L.) production is to enhance water use efficiency (WUE) and maintain or even increase grain yield. WUE, if defined as the biomass accumulation over water consumed, may be fairly constant for a given species in given climate. WUE can be enhanced by less irrigation. However, such enhancement is largely a trade-off against lower biomass production. If WUE is...
in order to study of drought tolerance in advanced grain sorghum lines, an experiment was conducted in a split-plot on randomized complete block design with three replications in experimental field of seed and plant improvement institute, karaj, iran during 2009-2010. irrigation regimes were assigned to main plots at three levels including normal irrigation (i1=60mm), moderate stress (i2=120mm)...
Defining interrelationship of growth analysis factors and yield of crop plants is important in the field crop production practices. This research was aimed at studying growth factors and grain yield of five maize hybrids, consisting of S.C.704, S.C.700, S.C.647, S.C.604, and S.C.301, using two 4-replicate RCBD experiments in Isfahan, in Summer 2004. While one experiment was irrigated normally, ...
Drought stress is considered as the most important limiting factor for growing of crops such as maize. Under low irrigation conditions, proper nutrition of plants can improve the effects of drought stress. This experiment was carried out in order to investigate the effect of nutrition management along with application of zeolite on agronomic traits of two hybrids of maize under deficit irrigati...
