Increasing Water Efficiency and Wheat Yield by Altering Irrigation Supplies

摘要

In Pakistan, a lack of appropriate irrigation methods and policy reforms poses serious dangers to the country's water and food security. Irrigation will take place in the future when water is scarce, when inadequate irrigation water becomes the norm rather than the exception. As a result, precise water application and irrigation management are required. In Pakistan's dry and semi-arid regions, this study looked at wheat grain production and water use efficiency under constrained irrigation practises. DSSAT was used to simulate yield and evaluate alternate irrigation schedule based on various irrigation levels, ranging from full irrigation to 65 percent less irrigation. Different amounts of irrigation had significant influence on wheat grain output and overall water consumption, according to the data. After evaluating the various irrigation levels, it was discovered that in semi-arid areas, the large amount of actual irrigation reduced WUE and wheat grain production.
