PRODUCTIVITY IMPACT OF THE MODERN VARIETIES OF RICE IN INDIA uri icon

abstract

  • The present paper analyzed the long-term yield growth and total factor productivity (TFP) growth by applying Tornqvist-Theil index method for two periods, namely, 1970-85 (early Green Revolution) and 1986-2000 (late Green Revolution), for major rice-growing states of India. The yield data shows an increasing long-term growth trend throughout the Green Revolution period in irrigated states where modem variety (MV) adoption was nearly complete. However, yield advances started to slow down for intensive irrigated rice systems in the 1990s, whereas tainted ecosystems have increased during the late Green Revolution period. The domestic spillovers of MV from irrigated to rainfed states is likely to be one of the contributing factors to increased TFP growth in ranifed areas after the 1980s. This implies that the MV of rice developed for irrigated ecosystems have also benefited substantially the rainfed-dominant eastern Indian states in the long run where partial irrigation facilities such as shallow tube wells were created after the mid-1980s.
