Abstract: With dwindling donor funds, research resources are becoming increasingly scarce. These limited resources must be allocated in the most efficient way among several competing research programmes, including those seeking to raise potato productivity. To do this, it is necessary to know the potential payoffs of different potato research programmes. Yet little information on these is available for §enya, or for Nakuru District, an important potato producing area in the country. The objectives of this study thus are to determine the payoffs to different potato research programmes in Nakuru District and hence provide guidelines for planning and priority setting in potato research in Kenya. Three potato research programmes are evaluated: crop ’protection; certificationpf seeds; and development of improved varieties. The basic hypothesis guiding the study istgt for these research technologies to be adopted they must be profitable The profitability of a technology is based on its impact on farm income The research thrust that raises farm incomes the most thus should be given highest priority. Data were collected from a targeted survey of 72 small scale potato producers in Molo and Njoro Divisions of Nakuru District and used to construct detailed potato production budgets for representative farm types. Analysis of these budgets indicate that research on crop protection has the highest impact on farm incomes and thus the greatest potential payoff followed by research on certified seeds. Given existing prices, research on recommended varieties may not significantly raise farm incomes and thus may have limited potential payoff. Other results reinforce these conclusions. Thirty two percent of the sampled farmers are using none of these three technologies, while only six percent of these farmers are using all of the three technologies. Adoption of crop protection is highest, which is expected due to its high payoff. Adoption of certified seed is low, apparently due to its high cost.
