  1. Note: Hurdle 1 is the probability of adoption and hurdle 2is the log of area planted upon adoption of the technology. The HH Control + CRE models include the mean and actual value of time-variant household control variables (not reported in this table to save space). Numbers in parenthesis are cluster robust standard errors. ***, **, and * are to 1, 5, and 10 % levels of significance, respectively. Source: NMBU and MU household panel survey.
