THE QUALITY OF POTATO TUBERS DEPENDING ON APPLICATION OF ADSORBENTS

Abstract

A potato is a field crop that is extremely important in Bosnia and Herzegovina, but according to all indicators the production is very unstable and unreliable (production volume and quality, average yields, range). For the research needs, the experiments were set up at two localities, Bijeljina and East Sarajevo, with use of superadsorbent of different composition (control variant; superadsorbent; superadsorbent enriched with growth stimulants; superadsorbent enriched with microorganisms; superadsorbent enriched with microorganism. The main goal of this research was to determine the influence of superadsorbent and locality on the chemical composition of the tuber.The analysis of the results showed that the use of different variants of the adsorbent had a highly significant effect on the examined properties, while the site influence had high significance for the dry matter, ash and starch content and significantly affected the nitrate content in the tuber. In the control variant, the tubers had the lowest dry matter content, the lowest starch content, but the highest in the variant with superadsorbent enriched with microorganisms. The highest ash content was in tubers in the variant with superadsorbent, and the lowest in the variant with superadsorbent enriched with growth stimulants, microorganisms and microelements. Using the superadsorbent enriched with growth stimulants, the lowest nitrate content in the tuber was determined, and the highest in the control variant. At the site in East Sarajevo, the tubers had a higher content of dry matter and starch, while the content of ash and nitrate was higher in Bijeljina.

Key words: tuber, starch, ash, dry matter, superadsorbent.
