Evaluation of Zero Tillage Technology in Maize - a Case Study in Warangal District of Andhra Pradesh

摘要

This study has been under taken to evaluate the zero tillage method of maize cultivation in Mandaripet village in Warangal district in Andhra Pradesh. This study analyses the contribution of zero tillage as a technology towards the net returns of Maize. The collected data were analyzed for costs and returns through averages and percentages, for input use efficiency through Multiple Linear Regression (MLR) and for evaluation of zero tillage practices in Maize as a technology through introducing a dummy into regression analysis. The results of the study revealed that Zero tillage technology saves on an average Rs.5035 required for land preparation when compared to conventional rabi rice cultivation. Zero tillage practices as a technology in Maize wasresulted in significant increase of net returns ranging from Rs. 9553 to Rs.16725 per hectare in the study area.
