Data were collected through interviews with 30 maize and 30 cassava farmers receiving rainmaking services and with the same number of both types of farmers not receiving rainmaking services. Comparisons of maize and cassava farming with and without rainmaking services were then made using regression analysis and ratios of farm cost and rainmaking service cost per unit. The results showed that rainmaking expenditure can be reduced by conducting rainmaking operations only from March to August. The quantity of rainfall affected statistically the maize and cassava yields. The service was less effective at reducing the drought problem in July.
