Resumen
Descripción
Production uncertainty is commonly believed to be an impediment to the adoption of less pesticide-intensive methods in agriculture such as integrated pest management (IPM). To investigate the effects of pest control inputs on yields and yield variability, data from a cross-section of San Joaquin Valley cotton producers were analyzed in a heteroskedastic production model. The results suggest that yields are increasing with soil quality, crop rotation, frequency of field monitoring, and the use of independent pest control advisors. Yield variability was not found to be significantly affected by production inputs, including pesticides and IPM practices with the exception of frequent contact with extension farm advisors which was found to contribute to reduced yield variability.
