In the study, the conventional production method of 8 kg/da P + 20 kg/da N application was tried with six different ash amounts (0, 500, 1000, 1500, 2000 kg/da poultry ash + 20 kg/da N). According to the values obtained from the study, the highest plant height (cm), the number of main stems (pieces), the specific gravity (g) 1500 kg/da ash application, the number of tubers per plant (pieces) from farmer conditions; average tuber weight (g), french fries oil rate (%), protein rate (%), big tuber rate (%) 2000 kg/da; chips oil rate (%), small tuber rate (%), dry matter rate (%) in the control plot where there was no application; Tuber yield per decare (kg/da), medium tuber ratio (%), marketable tuber ratio (%), were obtained from 1000 kg/da poultry ash application.eninfo:eu-repo/semantics/openAccessAverage tuber weightBig ruber rateTuber yieldMarketable tuber ratioArticle10.21597/jist.13221631414704821226845
