Interestingly non-adopters reported a much greater (but not statistically significant) level of income from non-cotton crops compared to adopters.
As a result, counting every language as a variable would have produced statistically unreliable results.

Effect modification by age category and season was statistically tested by adding this variable and its first-order interaction term to the final model.
