Abstract:

Potato is an important cash and food security crop in mid and highlands areas of eastern Ethiopia. However, the yield of the crop is constrained by many factors including improper application of irrigation amount and intervals. The field experiment was conducted at Haramaya University (Raare) research station during 2020 cropping season to assess the effects of furrow irrigation methods and intervals on tuber yield and quality of potato genotypes and to estimate water productivity and optimum irrigation amount for potato production. The treatments consisted of two potato genotypes (Bubu and CIP-392781.1), two furrow irrigation methods (fixed and alternate), and three irrigation intervals (six, eight and ten days) arranged factorially in a randomized complete block design with three replications. Phenological, growth, tuber yield and yield related parameters, tuber quality and water productivity were collected. The result revealed that the main or interaction effects of genotype, furrow irrigation methods and intervals significantly (P
