ABSTRACT
Three models were developed by using Linear programming with the objective of production, net benefit and labor employment maximization. The methodology and models developed were applied to command area of the Left Main Canal (LMC) and Right Main Canal (RMC) of the Som-Kagdar Irrigation Project. These models were applied for various levels of surface water availability i.e. number of canal running days in a season (70, 80, 90, 100, 110 and 120 days). The optimal cropping pattern has been derived using multi objective analysis. The optimal cropping pattern derived for 120 days canal running indicated that the net benefit, production and labor employment were increased by 18.75, 16.53, 16.58 percent respectively compared to existing cropping pattern. Similarly, optimal cropping pattern derived for 80 days of canal running for conjunctive use of surface water and ground water indicated that production, net benefit and labor utilization were increased by 12.73, 10.36 and 13.06 percent respectively compared to existing cropping pattern.
Key words :
Irrigation planning, linear programming model, labour employment maximization, optimal cropping pattern.
