IRRIGATION WATER MANAGEMENT (WM)

Course Objectives

1. The knowledge of irrigation water management to maximising crop yield and quality by developing irrigation and water management techniques can help growers demonstrate best practice to retailers and consumers.

2. This course will recommend ways for growers to improve crop performance by evaluating the different types of irrigation and water managements systems available.

3. To impart the knowledge of various irrigation methods which are more efficient to minimize the water loss and improve the water use efficiency of crop and water requirements of the crops,

4. There is an increasing need for efficient and effective irrigation and water management to maximise crop yield and quality whilst making best use of the water available.

5. Also impart the knowledge on Water requirements of crops, soil-plant- relationship, Irrigation requirements, duty and delta, Irrigation efficiencies, methods of irrigation, Quality of irrigation water.

Learning Outcomes

This course offers a wide scope for students in employment, skill development and entrepreneurial sector.
