CRP306 · UNIT 1 DEFINITION, IMPORTANCE AND PURPOSE OF IRRIGATIONS

Irrigation is generally defines as the artificial application of water to soil for the purpose of supplying the moisture essential for plant growth. The primary reason for irrigating crop is to supplement water availability from natural sources such as rainfall, dew, flood and ground water which seep into the root zone.

What you should be able to do

  1. Define and explain the importance of irrigation and drainage in crop production.
  2. Explain the relationship between soil, water, plant, and atmosphere.
  3. Calculate irrigation requirements for different crops.
  4. Describe methods for determining irrigation scheduling.
  5. Explain the causes and control measures for soil salinity, alkalinity, and acidity.
  6. Describe different types of soil erosion and methods for controlling them.
  7. Explain the importance of drainage and different drainage techniques.
