      abstract = {This paper uses farm-level data collected from a sample of  500 households in Hunan province, China, to analyze
the  impact of hybrid rice on input demand and productivity.  Based on regression analyses, it is found that,  compared
with conventional modern varieties, hybrid rice  uses about 4% less labor inputs, 2% less draft animal  services, and
6% more chemical fertilizers. The lesser  requirements for labor and draft animal services probably  arise from hybrid
rice's lower seeding rate. Due to  heterosis and high seed costs, the use of F1 seed is  economized to about one-third
to one-fourth that of  conventional varieties. Therefore, less labor and animal  power is needed for seed-bed
preparation and transplanting.  It is also found that, given the same level of inputs, the  yield advantage of hybrid rice
over the conventional modern  varieties is about 19%. Because of the productivity  potential, hybrid rice is a
candidate for the  second-generation "Green Revolution" in other parts of  Asia.},
