Evaluation of production costs, revenues and quality of potato tuber in organic and conventional farming system
MALECHA, Pavel
In 2009, there was an experiment with strains of potatos conducted in the region of Soběslav, at an altitude of 614 m. The aim of this thesis was to evaluate production costs, revenues and internal tuber quality in terms of organic and conventional farming system. The work observed dry matter, starch, reducing sugar, chlorogenic acid, vitamin C, nitrates and solanine. An attempt was made on two different strains of potatoes which have different growing season (Impala - very early, Adela - early). Adela variant showed an average of 7.51 t / ha higher yield than the Impala. Higher costs per tonne of potato production were in the conventional way of cultivation. From the evaluation of the internal quality of tubers, there was an apparent influence of the strain and cultivation method on the content of controlled substances. The executed test showed the health of potatoes grown in an organic and conventional way.
