to investigate the effects of sowing date (sd) and single irrigation (si) on grain yield of rainfed wheat varieties, this experiment was conducted as split-split plot arranged in a randomized complete block design (rcbd) with three replications from sep.2000 to sep.2004 at the main station of dryland agricultural research institute (dari) in maragheh. the treatments included three sowing dates ...

in order to investigate the effect of phosphorus fertilizer and spraying fe chellat in micronutrients absorption rate, rate of proline and soluble carbohydrates in bread wheat and some of its ancestral species in dryland condition, a factorial experiment was conducted with three factors consist of: p fertilizer (in two levels), spraying fe chellat (in two levels) and different species of wheat ...

Proso millet (Panicum miliaceum L.) is a warm season grass with a growing season of 60-100 days. It is a highly nutritious cereal grain used for human consumption, bird seed, and/or ethanol production. Unique characteristics, such as drought and heat tolerance, make proso millet a promising alternative cash crop for the Pacific Northwest (PNW) region of the United States. Development of proso m...

In semi-arid cropping regions where rainfall is variable, stored soil water important for reducing the impacts of dry periods; however, in-season evaporation limits yield potential. We tested productivity benefits protecting wheat and lentil crops from using inter-row polymer cover, when grown in southern Australia. For wheat, white polyvinyl chloride (PVCw) increased by 50% (561 kg/ha) 11% (40...

Abstract Global studies that quantify climate effects on crop yields using top‐down spatial frameworks are invaluable for assessing generalized world food supplies, yet do not contain the resolution necessary to identify local mediating of management. Our objectives were (a) what factors have historically affected winter wheat ( Triticum aestivum L.) in eastern Colorado, (b) how management may ...

the main purpose of rainfed farming is increasing the water productivity by applying suitable agricultural management including single irrigation (si) and panting time for wheat varieties. in order to study the si optimization and determination its optimal program, a field experiment was conducted as split-split plot based on a randomized complete block design with three replications for differ...
