It meets a long-felt need for a comprehensive analysis of cotton crop at the micro level; focussing on cost-return structure, farm-size and efficiency, labour absorption, elasticity of supply with respect to fixed inputs and variable inputs, demand for variable inputs with respect to cotton price, etc. It will prove an essential reading not only to the academics but also to the planners, policy-makers and government agencies. Review The Study aims at analysing the cost and return structure, determinants of yield, yield gap, supply and demand elasticities, absorption of labour and economic efficiency of the two farmer groups producing the LRA-5166 and MCU-5 varieties of cotton in two blocks of district Madurai. On the whole study offers a major base of techniques and systematic orientation of a research design. Dr. H.P. Singh, Review Projector (India), Vol. 8, Nos. 4-6.
