The research was conducted in the experimental field of the Faculty of Agriculture, Ekasakti University, Padang. October to December 2021. The research of giving is to get the best POC concentration of rice washing water and potato skins for the growth and yield of sweet corn (Zea mays saccharata Sturt). The experimental design used was a Randomized Block Design (RAK) with 5 treatments of 5 groups so that in total there were 25 experimental units, each experimental unit contained 4 plants so that the number of plants in the study was 100 plants. Treatment of POC concentration of rice washing water and potato skins as follows: A = 20% POC; B = 30% POC; C = 40% POC; D = 50% POC; E = 60% POC. Observational data obtained were analyzed statistically using variance. The results showed that the administration of POC rice washing water and potato peels had no significant effect on plant height, leaf length and longest leaf width, flowering age, cob length, cob diameter, number of rows on the cob, cob weight per plant, but significantly different on age. harvest. The best concentration of POC in rice washing water and potato peel on the growth and yield of sweet corn has not been found. Keywords: POC, sweet corn, growth, yield
