Th􀀚is paper reports the results of a study of productivity change in Kenyan agriculture. The data span the period from Kenyan independence in 1964 to 1989. Until now, no estimates of productivity for agriculture in Kenya have been available. Both multi-factor and labour productivity measures were constructed. Laspeyres indexing procedures were used. Our results indicate that while total production and input use have grown in the sector, productivity has stagnated through the period. Recent years have witnessed declining productivity. Attempts to use Cline's model to explain variations in productivity were unsuccessful. Coefficients of resear.ch and extension expenditures, education and weather variables were found to be statistically insignificant when these variables were regressed on productivity.
