Water Productivity Concept, Importance and Measurement in the Khapa Minor Irrigation Project

Abstract

In this study Irrigation water productivity is stated that as ratio of the crop output to the irrigation water applied by the farmer through irrigation system surface canals, tank, pond or the well and during the wheat crop growth. Thus irrigation is an economic activity and the farmer has to incur certain expenditure to apply the water (kg/m3). Studies were carried out to evaluate the wheat yield and water productivity for different varieties, irrigation method and depth of irrigation in Khapa and Magardha command area, which is located in Mandla district of Madhya Pradesh (India). In this study, Different irrigation application methods i.e. (sprinkler irrigation system, Border irrigation and flood irrigation) and different sowing methods were applied in wheat crop. These practices may reduce on-farm irrigation water applications and improve crop yields. Water management technologies like sprinkler irrigation is used in these command area, of conserving the available water resources and thereby sustainably improving the productivity as well as profitability.
