Analysing Growth Trends of Total Factor Productivity in Major Seed Spices of Gujarat, India

The present investigation was carried out to study the growth of input, output indices and total factor productivity of major seed spices of Gujarat. The Tornqvist-Theil index was employed to calculate the total output index, total input index and total factor productivity index. The total output indices were derived using 2011-12 as the base period and adjusted to obtain the TOI for major seed spices. In cumin, the growth rate of TFP indices was positive, approximately 1.09 per cent per annum. In fennel, the TFP indices exhibited a negative growth rate of approximately -3.96 per cent per annum. In coriander, the TFP indices demonstrated a significant growth rate of 1.94 per cent per annum, indicating moderate TFP growth for coriander in Gujarat.
