Course Name : Rainfed Agriculture and Watershed Management

Code(Credit) : ASAG 2211 (1-1-0)

Course Objectives

  • Students learn basic knowledge of rain fed agriculture and water shed management.
  • Study the crop adaptation and mitigation strategies, crop planning and crop management techniques.
  • Main objective is to increase / stabilize production of crops, forage, fruits, fuel and timber in rainfed areas by introduction of improved soil and moisture conservation measures, better crop and range land management practices.

Learning Outcomes

At the end of this course, the students will be able to

  • Student can able to understand about rainfed agriculture and its introduction, problem and prospects in India.
  • Rain fed agriculture is used to describe farming practices that rely on rainfall for water.
  • Student can able to understand objective, principles and component of watershed management .
  • Conservation of soil by adopting latest soil conservation techniques will help in obtaining higher production of Rainfed crops.
