Improving the quality of irrigation can be achieved by changing rate in accordance with level moisture reserves field areas at time watering, eliminating over-watering and water erosion soils. The purpose presented research was to improve technological process wide-reach circular sprinkler machines, which ensures reduction unproductive losses, improving irrigation. article discusses theoretical...

ABSTRACT- Efficient use of irrigation water for summer crops should be considered seriously due to rare occurrence of precipitation in summer. This research was focused on the assessment of water use efficiency for dominant crops of summer cropping pattern in the study area (i.e., maize and rice) via considering water productivity (WP) with different water management scenarios at farm level at ...
