In order to study the effect of drought stress and determination of effective traits on grain yield of wheat in normal and terminal drought stress conditions, 82 wheat genotypes were studied in two separate experiments using randomized complete block design with three replications during cropping season 2011-2012. Drought stress was applied in heading stage by limited irrigation. Set of 22...
in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...
This research was conducted to evaluate the effect of soil application of nitrogen (N) and iron (Fe) fertilizers on morphological traits and shoot mineral contents of bread wheat via factorial arrangement based on randomized complete block design with four replications. The factors included three level of nitrogen (100, 200 and 400 mg N kg-1 dry soil applied) as Ca(NO3)2 and three rate of Iron ...
the objective of this study was to investigate the effects of addition of pulses in crop sequences, crop residue management, and application of fertilizer n on soil nitrogen content, soil organic carbon, nutrient uptake, and its consequences for wheat yields. the field experiments were carried out from 2009 to 2012 in the sub-humid and sub-tropical zone of northern india. the treatments were (i...
in order to evaluate the effect of balanced application of chemical phosphorus fertilizer and seed inoculation with phosphate solubilizing bacterium and arbuscular mycorrhizal fungus and on the yield and yield components of maize (zea mays l.) under normal and limited irrigation conditions, a split-split plots arrangement based on randomized complete block design with three replications was con...
Decrease the plant height using the Rht genes is one of the main strategies to improve the resistance to lodging and fertilization and to increase the productivity in wheat. In Iran, like to other parts of world, these genes are entered to new introduced and released varieties. To study allelic diversity of two main dwarf genes (Rht-D1b and Rht-B1b) and their effects on morphological traits of ...
precise application of the n fertilizer rate is critical to achieve maximum yield. in major regions, empirical methods were used for determining n fertilizer requirement. these methods cannot take into account variation in management and environmental conditions on determining fertilizer requirement. crop simulation models can provide an alternative means of determining the optimum crop n requi...
the major aim of this study was to investigate the relationship between iq, eq and test format in the light of test fairness considerations. this study took this relationship into account to see if people with different eq and iq performed differently on different test formats. to this end, 90 advanced learners of english form college of ferdowsi university of mashhad were chosen. they were ask...
the effects of drought stress and different chimical and organic fertilizers systems were studied on wheat yeild. this experiment was conducted as split plot based on completely randomized block design (crbd) with four replications during 2009-2010. irrigation treatment was in i1(irrigation disruption from anthesis stage) and i2 (spike formation to harvesting) and i3 (full irrigation ,control t...
In order to study the grain yield attributes of sesame in the presence of nutritional treatments and different irrigation regimes, a factorial split-plot experiment was conducted based on randomized complete block design with three replications in Shahed University of Tehran, Iran during 2015-2016. The treatments included irrigation regimes (full irrigation and irrigation up to 65 and 75 BBCH s...
