Abstract: Direct seeding has been widely adopted in rice production due to its advantages of water- and labor-saving characteristics in China and other countries. This study aims to examine the effects of farmers’ adoption of direct seeding on the yield and fertilizer use in rice production in China. Using survey data of 1002 rice farmers in the Yangtze River Basin in China, the endogenous switching regression model is used to address the self-selectivity bias from both observed and unobserved heterogeneity. The results show that about 79% of surveyed farmers adopted direct seeding in rice production. After addressing the self-selectivity bias, the adoption of direct seeding increased rice yield among the adopters by 3.65%, and would have increased rice yield among the non-adopters by 1.54% if direct seeding had been adopted. In addition to its positive effect on rice yield, however, the adoption of direct seeding was also found to increase fertilizer use among the adopters by 19.84%, and would have increased fertilizer use among the non-adopters by 37.75% if direct seeding had been adopted. Moreover, farmers’ adoption of direct seeding exerted heterogeneous effects on rice yield and fertilizer use in terms of farm size and location.
