Abstract
Development and dissemination of hybrid rice technology can be one of the key strategies to meet
growing demand for staple food in Bangladesh. A number of initiatives for hybrid rice research
and development have been undertaken for the last couple of decades, but the adoption rate of
hybrid rice is not encouraging. In recent years, although some studies have investigated the
underlying socio-economic factors of hybrid rice adoption, research on estimating production
efficiency of hybrid rice is relatively few. In addition, there is a bias in sample selection inherent in
most of the technology adoption studies because rational farmers will always choose between
hybrid and inbred rice depending on a host of price and non-price factors. Furthermore, the
production function that uses observations from a single variety only may produce biased
estimates of production efficiency. Given this backdrop, this paper adopted the recently developed
method that corrects for sample selection bias in a stochastic frontier framework and
simultaneously identifies the determinants of hybrid rice adoption and its farm-level
productivity and efficiency while relaxing the assumption of perfect efficiency of the individual
producers. A survey was conducted to collect primary data on inputs and outputs of hybrid and
inbred rice production. Some key information on the socio-economic characteristics of the
sample farmers was also collected. Using pre-tested structured questionnaire, a total of 336 and
180 rice farmers were selected and interviewed at six districts of Bangladesh for the crop year
2004 and 2005, respectively. Model diagnostics reveal that serious selection bias exists,
justifying use of our sample selection approach. The results reveal that the producer’s decision to
choose hybrid rice is positively influenced by gross return per unit of land but negatively affected
by a rise in relative prices of labour and phosphate fertilizer. Adoption of hybrid rice is
significantly higher for pesticide and organic manure users. Land, irrigation and mechanical power
are the significant determinants of hybrid rice productivity. Productivity of hybrid rice varies
across regions. The mean technical efficiency of the hybrid rice producers is estimated at 0.86 with
a range of 0.55 to 0.97, implying substantial scope to improve production by eliminating
inefficiency. Policy implications include price policies to improve hybrid rice price, tenurial
reform aimed at consolidating farm size and smooth operation of the mechanical power services
and investment in irrigation to expand hybrid rice adoption and productivity in Bangladesh.
