Total Factor Productivity and its Sources of Growth for Rice in Punjab

The present study was conducted to measure total factor productivity and its sources of growth of rice cultivation in Punjab. Törnqvist Theil Index was applied to measure total factor productivity using output and input data of rice crop. The study was based on secondary data collected from various sources. The results of the study indicated that positive and significant growth of rice production was due to the growth of both area and yield. Reduction traditional inputs and increment of modern inputs showed farmers adopted modern technology for cultivation of this crop. Declination of land and fertilizer productivity supported the fact that there was need of concerned for effective use of these inputs. The state had positive and significant total factor productivity growth in the overall study period (1994–2014). Only expenditure on agricultural research and education had the positive and significant effect on total factor productivity growth in Punjab, indicating this factor should be maintained as it is showing a prospect in the future growth of TFP in this state.
