Abstract:
... The demand for freshwater resources has increased in recent times and has been exacerbated by escalating global population and increasing drought indices in the world’s agricultural zones. Irrigated agriculture is inevitably a wasteful water user that has deprived other sectors of the scarce resource. Improving water use efficiency in irrigated agriculture is therefore crucial for sustainable agri ...
