abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
one of the effective tools for identifying land resources and assign them to the best and most profitable forms of land productivity, susceptibility of agro-ecological zoning . in this study agro-ecological zoning of satellite imagery and gis were used. after agro-climatic zoning (based on isorain, isothermal and length of growing period maps) and agro-edaphic zoning (based on soil, slope and l...
In complex task domains, such as games, students may exceed their teachers. Such tasks afford diverse means to tradeoff one type of performance for another, combining task elements in novel ways to yield method variations and strategy discoveries that, if mastered, might produce large or small leaps in performance. For the researcher interested in the development of extreme expertise in the wil...
Water deficit is one of the most important abiotic factors limiting growth, which adversely affect growth and crop production. In order to study the relationship between kernel size and phenological characteristics on grain yield, 46 local bread wheat genotypes along with four varieties were evaluated in randomized complete block design with three replications under irrigation and water deficit...
Longitudinal wheat yields in China have declined recent times due to climate change, more frequent natural disasters, and suboptimal agronomic management. To date, it has been unclear which factors predominated yield penalties realised hitherto Hubei Province. This study aimed identify key limiting production across systems agroecological regions, provide a basis for increasing crop while engen...
