摘要

Complexity of climate variability and application of pesticides on rice production in Nigeria was investigated. A multi-stage sampling procedure using a structured questionnaire was utilized to sample 401 rice growers. Data for the study were gathered from primary and secondary sources and analyzed using descriptive statistics, the local average treatment effect (LATE), the beta regression model, principal component analysis (PCA), and the autoregressive distributed lag (ARDL) model. The rice farmers were found to be of fruitful age (56 years), male (85%), educated (mean = 12.0), and experienced (18 years). The majority of the rice farmers (89.8%) were conversant with climate change variations, and (50.4%), had a high degree of pesticide use. Climate variables such as temperature, rainfall, number of wet days, evaporation, and sunshine hours were discovered to have both beneficial and adverse significant effects on rice productivity. The use and application of pesticides on rice field increased yield by 987.01% and 710.6% with a negative decrease of 247%. Age, gender, access to credit, education level and climate events were significant determinants of pesticide usage and application among rice farmers. Increased crop failure (0.703), increased soil salinity and acidity (0.700), decreased yield (0.711) and increased insect/pest infestations (0.670) were noted as major perceived consequences of variability in climate and pesticide use. Rice growers were recommended to seek for early climate signals/forecast before embarking on rice cultivation and to adhere strictly to specified instructions regarding pesticide application.
