Notes:

A test used to compare the means of explanatory variables between adopters and non-adopters under the assumption of unequal variance. SD is standard deviation; ***, **, * show difference between adopters and non-adopters is significant at 1, 5 and 10 per cent levels, respectively. Shock index is calculated by dividing the number of shocks that happened on a plot by seven. These shocks are drought, flood, erratic rainfall, animal attack
