Optimal Cropping Pattern for Adoption of Micro-Irrigation Methods in Canal Command Area - A Case Study

Abstract

Currently the micro irrigation methods are mainly adopted on farms with irrigation from tube wells or dug wells. However, in view of increasing scarcity of water for irrigation and need to increase food production, it is important to adopt these methods in canal command area. A linear programming model was formulated to suggest the optimal cropping pattern under micro irrigation method in canal command areas. The objective was to achieve the maximum such as net returns. The objective function of the model was subjected to the constraints such as total available water and land during different irrigation periods, crop area restrictions, and system reutilization constraints. The system reutilization constraint facilitated utilization of micro irrigation system among the different short duration seasonal crops having similar system geometry requirement. The model was applied to command area of direct minor no. 3 of the Mula Irrigation Project, Ahmednagar, Maharashtra. The model gave optimal cropping pattern for
