Abstract
The net revenue from an activity is obtained by subtracting the cash expenses incurred in production from the gross revenue. Gross revenue is the sum of all receipts from the sale of a crop. This study was carried out in Ogun State, Nigeria (latitude 7o 00ꞋN and longitude 3o 35ꞋE) to analyse the revenue of cassava farmers who were involved in improved practices. The simple Random Sampling technique was adopted in the selection of 336 farmers from the study area. Data were analysed using frequency counts, percentages, budgetary technique as well as Chow test. Results showed that there was a steady increase in the revenue until it reached the peak. Thereafter, it fell below the zero lines into the negative. Also, all (100.0%) of the participants had formal education and belonged to a farmers’ association. The average farm size was 1.64 hectares. The study, therefore, recommends regulation of cassava price so that it will not fall below a certain fixed point. It also recommends the government purchase of excess cassava output directly from farmers in order to avoid a market glut. Finally, value addition should be promoted to boost income derivable from cassava sales.
