This study was specifically be conducted among community members who was selected from the four main villages of Buhara Sub County and other important respondents who was selected from other parts of kabale district. Ordinary least squares productivity function's restricted logarithmlikelihood function's value under the null hypothesis (H0) is -50.32, while the unpredictable Cobb-Douglas function's unrestricted log probability function's value under the alternative hypothesis (H1) is -46.759. This indicated that LR = -2*(-50.32+46.759) =7.122 was the generalized likelihood-ratio (LR) statistic for assessing the lack of a technological inefficiency effect from the frontier. This value was more than the 5% level of significance's crucial 1) (5%, 2 value of 3.84. Producers ought to be given access to trustworthy markets where they may sell their potatoes at competitive prices. It is crucial to construct effective value chains, enhance market connections, and forge alliances with buyers, processing units, and retailers.
