Comparative Analysis of Rice Production under Various Irrigation Conditions in the Gangrel Dam Command Area of Chhattisgarh, India

This study undertakes a comparative analysis of rice production under various irrigation conditions in the Gangrel dam command area of Chhattisgarh. Data were collected from 192 rice farmers using a percentage random sampling and analysed using appropriate statistical tools. The results indicate that the highest cost was found under assured irrigation followed by protective irrigation and lowest under rainfed farming which was Rs. 81492.51/ha, Rs. 73,605.54/ha and Rs. 70,181.10/ha respectively. The gross returns from cultivation, as determined by total output, was Rs. 1,87,699.41/ha, Rs. 1,83,251.60/ha and Rs. 1,64,522.50/ha under assured, protective irrigation and rainfed farming respectively. The net returns obtained under assured, protective irrigation and rainfed farming was Rs. 106206.75/ha, Rs. 109646/ha, and Rs. 94341.44/ha respectively. The input - output ratio varied under different irrigation conditions with protective irrigation at 2.48, followed rainfed farming at 2.34 and lowest in assured irrigation at 2.30 rupees. Protective irrigation yields a greater input-output ratio. The Cobb-Douglas production function was used to estimate resource use efficiency by analysing the marginal value product (MVP) of all irrigation conditions, under assured irrigation, manure, insecticide, and irrigation was underutilized and can boost productivity, while seed, fertilizer, labour, and machine power were overused and inefficient. In protective irrigation, fertilizer, manure, and insecticide was efficient, whereas seed, labour, and machinery show overused. In rainfed farming, insecticide, manure, and fertilizer remain productive, but seed, labour, and machine power are again inefficient and overutilized.
