INPUT USE EFFICIENCY IN PADDY WITH SPECIAL REFERENCE TO WATER - A TRANSLOG PRODUCTION FUNCTION APPROACH

Abstract

A study conducted in Krishnagiri Reservoir Project (KRP) in Tamil Nadu indicated that the water use efficiency in Navarai paddy was the highest in tail region with 32.85 kg/ha cm of water, followed by middle and head regions. Translog production functions were employed for each region to analyse the input use efficiency. The results clearly showed that labour and irrigation water were overused in the ayacut area whereas the inorganic fertilizers were underutilised and there is scope for increasing the productivity of navarai paddy through rational use of these scarce resources.

Keywords: Translog, marginal product, elasticity, efficiency
