it is suggested that cultivars of wheat (triticum aestivum l.) with regulated growth and development would be able to produce higher yields under water-limited conditions, which is crucial in future food production. water use efficiency (wue) is worthy of exploration in this regard. in this study, the effects of nitrogen fertilizer levels (0, 40 and 80 kg nha-1) and a plant growth retardant (ch...
this study investigated the potential role of age in inductive and deductive grammar learning among iranian foreign language learners. the experimental population consisted of our randomly selected samples including two groups of children (with age of exposure to english within 8-13), and two groups of adults (with age of exposure to english within 11-13). thus, the comparison was between ch...
Supplying adequate amounts of soil N for plant growth during the growing season and across large agricultural fields is a challenge for conservational agricultural systems with cover crops. Knowledge about cover crop effects on N comes mostly from small, flat research plots and performance of cover crops across topographically diverse agricultural land is poorly understood. Our objective was to...
