COMPARATIVE ANALYSIS OF PRODUCTION EFFICIENCY OF HYBRID RICE AND INBRED VARIETIES IN BANGLADESH: A CASE STUDY OF JOYPURHAT DISTRICT

Abstract

This study discusses the pattern and sources of technical efficiency of rice farm in Bangladesh of Joypurhat district. For the measurement of technical efficiency, we have used Cobb-Douglas stochastic frontier model and estimated technical efficiency by specifying a Cobb-Douglas stochastic frontier production function. We have also tried to explain MLE for some specific input variables for various rice productions (HB, HYV, and Aman). We have obtained technical efficiency scores as of all 240 rice farms. The stochastic frontier presents that signs of the βi parameters of the Cobb-Douglas stochastic frontier are all positive, as expected. The estimated coefficients of land, labor, fertilizer, irrigation and pesticides on the production of HB, HYV and Aman are positive and significant. The value of R², R (Adjusted) and F for all rice variety indicates the well fitted for the model. The technical efficiency of hybrid rice, high yielding variety and aman are estimated for four unions in Joypurhat district in Bangladesh and technical inefficiency models are also presented as a function various form specific socio-economic variables. We have identified how these factors affect the efficiency performance. The maximum likelihood estimates the parameters of the Cobb-Douglas frontier production model for hybrid rice, high yielding variety and aman which are described.
