Study on Water Resources Optimal Allocation of Irrigation District and Irrigation Decision Support System

This paper develops the system of optimal allocation of water resources in irrigation district and irrigation decision support which integrates technologies of decision support, information management, information search and so on. It has the multi-function of water production function calculation, crop water requirement calculation, water resources optimal allocation and realtime amending the ...

Identifying Irrigation Strategies for Improved Agricultural Water Productivity in Irrigated Maize Production through Crop Simulation Modelling

Identifying irrigation strategies that improve agricultural water use efficiency (WUE) have a pivotal role to play in sustainable water development. In this study, the AquaCrop model was used to examine the impact of different irrigation scheduling options on yields to identify viable strategies to enhance WUE for irrigated maize. Two scheduling scenarios at water application depths ranging fro...

Effect of Polluted Irrigation Water on Crop Plants

“Earth provides enough to satisfy every man's need, but not every man's greed.” Rapid industrialization has resulted in the generation of liquid, solid and gaseous wastes in such a huge quantity that a serious threat is likely to be posed to the quality of water in the years to come. The crux of the present day environmental problem concerning the water is further accentuated due to everyday po...

Response of tomato to irrigation with saline water applied by different irrigation methods and water management stratigies

In a field experiment the effects of irrigation with saline drainage water (seasonal average of 4.5 dS/m) and non-saline water (0.55 dS/m) applied by two different water management strategies (cyclic or blended saline water with non-saline water in different ratios) and two different irrigation methods (drip or furrow) were studied on growth and productivity of tomato (Lycopersicon esculentum M...
