The study has analysed the economics of rice production under different systems of irrigation, viz. canal, well and tank irrigated conditions. The study area was Thanjavur, Sivagangai and Salem. The analysis has shown water-use efficiency to be the highest in well irrigated rice cultivation, followed by tank and canal rice cultivation. The optimality of input use has shown that none of the resources in the three irrigated systems of rice cultivation was used under optimum efficiency level since MVP to factor price ratios were not equal to one. The mean technical efficiency was 0.76, 0.75 and 0.71 for canal, well and tank irrigation system, respectively. The results of economic and allocative efficiencies have shown that the selected farmers have better ability to achieve the maximum output with given inputs. The determinants of technical efficiency in rice cultivation have been found as the level of education and size of landholding.
