Determination of the Effect of Poultry Ash Application on Agro Morphological and Quality Properties of Potato (Solanum tuberosum L.)

Abstract

This study was carried out in Bolu conditions in 2021 to see the effect of poultry ash, which has the potential to be a nutrient in terms of being rich in minerals and is also a soil conditioner, on the yield and quality characteristics of potato (Solanum tuberosum L.). 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.
