due to contiguous city of ravar with lut and dasht-e kavir desert, and weather conditions, water is one of the rarest agricultural inputs in this city. pistachio allocates 90% of garden and 73% of agricultural lands of the city and it is the most important agricultural product in this region. a major source of agricultural water supply in this area is groundwater. low price of water on one side...

The pressure on water resources is due to different factors that affect agricultural development for food security. Large lands are not irrigated because of limited and poor irrigation management. This results in crop productivity. Therefore, this paper focused finding alternative techniques management solve the problems productivity diverse species. Although there options saving managing impro...

in order to obtain the maximum benefit, yield increasing and its stability a supplemental irrigation field experiment was conducted as split plot arranged in a randomized complete block design (rcbd) with three replications during 1999-2002 at maragheh agricultural research station of dari. the treatments included four levels of irrigation (average of three years: 0, 95, 151 and 207 mm) as main...

The Water Accounting Plus (WA+) framework uses open access remote sensing and GIS data hydrological model output. This Budyko hypothesis thus makes use of ‘green’ water ‘blue’ accounting. We applied the WA+ to Subarnarekha basin, India, assess total consumptions land productivity (LP) (WP) for a period 12 years from 2003 2014 by using satellite sources. in basin 2013–14 (wet year) 2010–11 (dry ...

In Nigeria irrigated agriculture is an important tool for economic growth, food security, and poverty reduction during dry periods of rain-fed agriculture. The concentration and composition of dissolved constituents in water determines its quality for irrigation use. Water quality studies strongly suggest that agriculture is a leading source of water quality problems, due to pesticides and othe...

Intrinsic water use efficiency (WUEi) in trees is an indication of the ratio of carbon assimilation to the rate of transpiration. It is generally assumed that it is a response to water availability. In agricultural research, the question of drought tolerance by increased WUEi has been well studied. In general, the increase is a trade-off for productivity and is therefore not desired. For forest...
