The dependent variables of models (1) and (2) are the natural logarithm of the coefficient of variation of yield and the natural logarithm of the coefficient of variation of revenue per ha, respectively. GST is the growing season average temperature and GSP is the growing season precipitation. “Coeff” stands for coefficient and “SE” for robust standard errors. Statistical significance levels:  = 1%,  = 5%, and  = 10%.
