Description
Summary:The present study was conducted of estimating the total factor productivity (TFP) growth of rice and its contribution to rice production in Assam and examining the determinants of TFP. The study was carried out for two decades, from 1991-92 to 2010-11, using secondary data, estimated us the Tornqvist Theil index. The input, output, and TFP indices were calculated at a constant price (for 1991-92) of the inputs and outputs to nullify the nominal price effect. Again, the indices were computed for per hectare area and total area under rice in the state to know how efficiently inputs were utilized in both situations. To evaluate the determinants of TFP in Assam, regression was carried out by using Cobb Douglas production function. The study revealed that TFP growth for rice at a constant price was found to be positive in both per hectare area and total area for the study period. Determinants like investment in agriculture and allied activities, expenditure in agricultural research and education, HYV area, rural literacy, irrigation, and cropping intensity were found to have a positive impact on TFP.
