A Comparative Study of Technical Efficiency between Canal and Tank Irrigated Paddy Farms Using Corrected OLS Models in Tamil Nadu
Background/Objectives: To make a comparative study between canal and tank irrigation environments of paddy farms.
Methods: Corrected ordinary least square method was used to determine technical efficiency in paddy production in their respective irrigation pattern. Further the study has assessed the effect of farm specific socio economic factors affecting the technical efficiency. This study was conducted in Cauvery delta zone of seven TALUKS about canal irrigation and Southern zone of four TALUKS about tank irrigation. Ultimately, there were 218 sample points under canal irrigation and 106 sample points under tank irrigation for two years (2009-10 and 2010-11). The data were obtained from the cost of cultivation scheme of Tamil Nadu centre.
Findings: The results of Cobb Douglas production function indicated that seed, labour hours and pesticide cost are the inputs that significantly influence the yield of paddy in canal irrigated paddy farms; while, seed, fertilizer, labour hours are the are the inputs that significantly influence the yield of paddy in tank irrigated paddy farms. Besides, the qualitative variable namely education and seasons are significant in canal irrigated paddy farms while age and area were significant in tank irrigated paddy farms. The output oriented mean technical efficiency was found to be 86% in canal irrigated farms whereas 91% in tank irrigated farms. The study results also implied that in controlled irrigation condition namely tank irrigation, particularly in canal fed tanks when water availability becomes relatively more consistent, the yield levels were higher, and the mean technical efficiency was also relatively higher.
