understanding the relationship between sink and source in maize is of prime importance in maize growing regions. in this study, a field experiment was carried out during spring and summer 2007 in the experimental field of the college of agriculture, shiraz university, to examine the effects of source restriction (defoliation) on sink size (yield and its components) of sc704 maize hybrid. a fa...
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...
to study and determine effect of salinity on relationship between agronomic characteristics and grain yield, 167 of the seri/babax recombinant wheat inbred lines (ril) together with two parents were evaluated using alpha latice design with two replications under two conditions (salt stress and normal), in zabol field station in 2011-12 cropping season. fourteen traits including: some a...
In order to investigate the effects of drought stress and plant density on yield and some physiological characteristics of pinto bean (Phaseolus vulgaris L. cv. C.O.S16), a field experiment was conducted in split plot arrangement based on randomized complete blocks design with three replications at Research Farm of Yasouj University, Yasouj, Iran, in 2010. Treatments were conventional irrigatio...

introduction phosphorus (p) is an essential element in crop nutrition, which can be growth limiting or an environmental contaminant, if present in excess. on the other hand, tillage practices have a direct effect on behavior and availability of soil p. since, application of different tillage methods lead to different patterns of soil phosphorus distribution, hence p fertilizer needs and p avail...
translation studies have become an accepted academic subject and books, journals and doctoral dissertations appear faster than one can read them all (bassnet and lefevere, 1990). but this field also brought with itself so many other issues which needed to be investigated more, in the heart of which, issues like ideology, ethics, culture, bilingualism and multilingualism. it is reported that ove...
Phosphorus (P) deficiency is a major constraint to crop production on highly weathered, lowactivity clay soils in the humid zone of West Africa. Past research suggested a linear relationship between grain yield and P uptake over a range of fertilizer P applied to upland rice cultivars. However, there is lack of information on how these relationships are affected by the long-term fertilizer ...
source limitation during grain filling is important for both management and breeding strategies of grain crops. there is little information on the sensitivity of grain yield to various source-sink ratios in various wheat (triticum aestivum) cultivars. the objective of the current study was to evaluate the response of grain yield as well as yield components to different source-sink ratios during...
the ability of composing a coherent and extended piece of writing in second language is considered as a fundamental factor to convey information and ideas of learners through the academic issues. although learners may achieve a perfect academic writing skill through assigning the l2 tasks in content based instruction, but demonstration of their abilities may be related to their ability in l1 es...
