Theme-III-5-Management of irrigation water through tensiometer in Paddy - A case study in the Kapurthala districts of Punjab.

Abstract

Water resources of a Punjab consist of both the surface water and the ground water resources. The per capita water availability of India is decreasing due to ever increasing population Agriculture utilizes nearly 80% of available water resources in Punjab. During the last few decades there has been a spectacular development in agriculture in Punjab due to Green Revolution, which enables Punjab to contribute largely in Nation's food grain production. The state has developed its water resources by laying irrigation canals and we remove much more than we have. Facts states that per year we required 43 lakh ha-m of water to grow our crops in Punjab but what we have in our pocket is 30 lakh ha-m. Thus, we drawl3 lakh ha-m of excess water from the ground which is a matter of great concern and attention. In this connection, PAU has launched a new technology by which farmers provide water to their paddy fields only when it required and our study from the last five years concluded that we can save upto 33% of water without having any adverse effect on our paddy yield.
