Abstract

The aim of this research is to analyze the dependence of the quality indicators of 'Adora' potato tubers on various growing conditions. The research was done on potato tubers of 'Adora' variety, which were grown in Marijampolė region in 2011-2012 in two plots with differing agrochemical indicators. The analysis of the quality indicators of the potato tubers was carried out with standard methods: the amounts of dry matter, starch, vitamin C, soluble matters and potassium were tested in the Laboratory of raw materials for food, zootechnical and agronomical analysis in the Institute of Agricultural and Food science of the Faculty of Agronomy in ASU. The results of the research were evaluated with dispersive analysis using STAT software from the „SELEKCIJA“ packet (Tarakanovas, Raudonius, 2003). Amounts of starch and vitamin C accumulated in tubers of 'Adora' variety grown in the soil with high levels of phosphorus and potassium were slightly higher, and those of nitrates and potassium were substantially lower in comparison with the tubers grown in soil with high levels of phosphorus and normal levels of potassium.
