Tuber yield and starch content in potato of a different ripening in agro-ecological conditions of northern Montenegro

Abstract

The results of multi-year research on tuber yield and starch content of several potato varieties in the agro-ecological conditions of northern Montenegro are presented. The investigated varieties were of different ripening times, from early varieties (Riviera), medium early (Almera, Aladin and Bounty) to medium late (Agria, Margarita, Kennebec and Desiree). Research was conducted in 2015., 2016. and 2017, on acidic, brown soil. The experiments were placed at three different altitudes and therefore at three different climatic locations: Nedakusi (556 m), Sutivan (680 m) and Orahovica (900 m). Trials were set up in three replicas, using standard methodology in a random block design. Analysis of variance showed that the yield of tubers for sale and the total yield of tubers varied significantly depending on the genotype, year and altitude, that is, the location of the experiment, as well as their interactions.
