a novel silver (ag) nanocomposite electrode was proposed that fabricated from metal nanostructures and ionic liquids. the combined application of unique properties of nanomaterials and ionic liquids in the design of this ag nanocomposite results in electrodes with interesting advantages compared to the conventional metal disk electrode. in the first part of this thesis, the elecrocatalytic eff...
In order to investigate the effects of different nitrogen fertilizer levels and water stress during milky and dough stages on grain yield, yield components and water use efficiency of corn hybrid SC 704 (late maturing, non prolific and dent type), a field study was conducted. The factorial design of the study comprised of a randomized complete block with four replications. Four levels of nitro...
Breeders have successfully improved maize (Zea mays L.) grain yield for the conditions of the US corn-belt over the past 80 years, with the past 50 years utilizing single-cross hybrids. Long-term improvement for grain yield under water-limited conditions has also been reported. Grain yield under water-limited conditions depends on water use, water use efficiency, and harvest index. It has been ...
introduction moisture limitation is considered as one of the important limiting factors in soybean growth. drought stress affects different aspects of soybean growth through making anatomical, physiological and biochemical changes (tarumingkeng & coto, 2003). under dry tension condition, there will be a disturbance in transmitting nutrients, but some useful soil fungi such as mycorrhiza improve...
the purpose of this study was to investigate how english language teachers in mashhad who teach students in the pre-university cycle perceived the impact of the efltee on their teaching. the target population was nearly all pre-university english language teachers in seven districts of mashhad in the scholastic year 2008/2009. a survey questionnaire which consisted of (36) likert type items, wa...
abstract water and nitrogen are the main limiting factors affecting agricultural production in arid and semiarid regions. therefore, improving the efficiency of these factors is very important. the method of fertilizer application is affecting water and fertilizer use efficiency. the objective of this study was to investigate the effect of furrow fertigation on fertilizer use efficiency (fue), ...

Traits Associated For Adaptation To Water Limited Environment Of Cereal Crops A Review Of Literature
Cereal crops mainly cultivated as a rainfed crops, where grain yield is often limited by terminal drought stress. Therefore, ability of plants to withstand drought is an important aspect of crop production in water limited conditions. In this context grain yield is closely related to post-anthesis water availability. Hence, grain yield can be increased by restricting pre anthesis water use to m...
Photosynthesis and wheat grain yield responses to supplemental irrigation with different amount of applied water under dryland conditions were investigated. Therefore, a two-year field experiment was conducted research farm of College of Agriculture, Shiraz University during 2004-2005. Five levels of irrigation including dryland conditions, irrigation at stem elongation, booting, flowering an...
Water stress is one of the most important factors limiting the growth and production of crops in arid and semi-arid regions. To evaluate the effect of mycorrhizal fungi species on the growth and yield (quantity and quality) of Onobrychis sativa under water deficit condition, a greenhouse factorial experiment based on completely randomized design (CRD) with three replications was conducted in 20...
