The dataset contains the results of two surveys realized in 2019 and 2020 in the Municipality of Tenado, Burkina Faso. The surveys were conducted in October 2019 and in November 2020 using structured questionnaires translated and administered in the local language by trained enumerators. Moreover, yield plots were placed in farmers’ fields and yield was measured on site. The sample at the Tenado site consisted for each survey in approximately 300 farmers (150 treated and 150 control) in 12 villages for each year. The treatment is the training in the use of Weather and Climate Services in agriculture. The control group is random and represents the entire population. The treatment group is also random, from the participants in training. Observed variables are: N. seedings Quantity of seeds (kg/ha) N. fertilizations Quantity fertilizers (kg/ha) Working days Yield (kg/ha) Costs (FCFA/ha) Seeds cost (FCFA/ha) Fertilizers cost (FCFA/ha) Labor cost (FCFA/ha) Income (FCFA/ha) Gross benefit (FCFA/ha) The market price of sorghum and the cost of seeds, fertilizer and labor were considered stable over the 2 years and in particular the sorghum price was 200 FCFA per kg, while the costs were 350 FCFA for 1 kg of seeds, and 450 FCFA for 1 kg of fertilizer. Labor cost is accounted as the opportunity costs of working time considering that 1,500 FCFA is the daily wage in agriculture. Income was computed multiplying yield by the price of sorghum and the gross benefit is the income minus the costs.
