To meet the challenge of a limited and costly water supply, South African sugarcane growers will have to find ways of increasing the efficiency of irrigation to maintain high cane and sucrose yields. The term ‘water use efficiency’ (WUE) is generally used as a measure of the overall effectiveness of water (either rainfall or irrigation, or both) for crop production. WUE can be defined as cane y...

abstract- a detailed understanding of crop rooting systems will facilitate water use reduction, optimized nutrient uptake and irrigation scheduling more efficiently. a field experiment was conducted during 2005-2006 to investigate sugar beet rooting depth growth, irrigated with three irrigation methods (subsurface drip, surface drip and furrow) and two water qualities (recycled wastewater: ec= ...

The North China Plain (NCP) produces about half of the winter wheat yield in China; therefore, it is essential to improve grain yield, biomass, and water productivity (WP) under current shortage conditions this area. In study, AquaCrop model was used for calibrating validating crop canopy cover, soil content, evapotranspiration (ETC), WP an irrigation scheduling 50%, 60%, 70% field capacities w...

Abstract The crop water stress index (CWSI) is a valuable tool for monitoring and quantifying water stress as well as for irrigation scheduling. A field experiment was conducted during spring and summer 2012 at Research Station of College of Agriculture and Natural Resources of Darab, Shiraz University, Iran, to determine CWSI of  turfgrass for irrigation scheduling. Four levels of water regime...

Reservoirs are principal water resources that supply irrigation water to paddy fields and play an important role in water resources management in South Korea. For optimal irrigation reservoir operation and management, it is necessary to determine the duration of irrigation water shortages. Management of reservoir operation and irrigation scheduling should take into consideration essential varia...
