Abstract

The purpose of the experiment was to investigate the impact of different herbicides on the height of the potato plant as well as on the number of tubers per plant. In field conditions, five potato cultivars were studied: Desire, Kondor, Ultra, Carlita, and Arnova, as well as six different variants of herbicides: absolute control, mechanical control, pendimethalin, linuron, metribuzin PRE, and metribuzin POST. The experimental scheme was a randomized block with three replications for each variant with experimental plot sizes of 21 m2. The experiment was carried out in the locality of Gorno Sedlarce, Tetovo. Based on the obtained results, the following conclusions were established: The cultivar Desire reached the highest height in the H1 variant and 54.2 cm, while the lowest height in the H4 variant was 43.4 cm, the Kondor cultivar in the H1 variant and 48.3 cm, while the lowest in the H4 variant also 42.1 cm, the Ultra cultivar in the H2 variant also 69.2 cm while lower in the H3 variant also 66.8 cm, the Carlita cultivar in the H2 variant 49.7 cm while lower in the H4 variant also 42.7 cm, the cultivar Arnova in the H1 variant 60.1 cm while the lowest in the H4 variant 46.8 cm or on average all types of potatoes reached the highest height in the H1 variant 55.7 cm while the smallest in the H4 variant and the 46.8 cm one. According to the results obtained for potato height, it can be noticed that only in the Arnova cultivar the H1, H2 and H5 variants are significant at the 0.05 level and in the H4 variant at the 0.01 level. Meanwhile, regarding the average of all cultivars, we have no significance at both levels in all variants.
