The objective of this study is to estimate technical efficiency of farm machinery manufacturers in Central India. The statistical test for the presence of technical inefficiency has been performed using stochastic frontier production model. Data envelopment analysis (DEA) has been used to identify existing returns to scale in farm machinery manufacturing units. The slacks-based DEA has been used to estimate input excess and output shortfall in the manufacturing system. Results indicate that out of the total variation, 69% was due to technical inefficiency in the manufacturing system, whereas 31% was due to stochastic errors. The estimated radius of stability was varied from 0 to 1.74 and the classification (efficient and inefficient manufacturers) was found robust against data alteration within the estimated radius of stability. The results showed that a manufacturer has to increase annual turnover by INR 40.7 million to become efficient.Keywords

The study investigates the trend and spatial distribution of the draught animal population in Madhya Pradesh, situated at lat. 21.6°N to 26.30°N and long. 74°90¢E to 82°48¢E. Draught animals dominated around 20% (3 million hectares) of the net sown area of Madhya Pradesh, with power availability of more than 0.37 kW/ha. A 1% increase in tractor density reduces the draught animals by 0.89%, and a 1% increase in percentage forest area increases the draught animals by more than 0.5%. The spherical form of the semivariogram model with an estimate of nugget, sill and range as 0, 500 and 1.6 respectively, was used in kriging. The neighbour search radius and the minimum number of neighbours were taken as 3° and 20 respectively.Full Text
