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 investigated: 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 vegetative year 2020 in the locality of Gorno Sedlarce, Tetovo. Based on the obtained results, the following was established: Cultivar Desire reached the highest height in the H4 variant, also 59.4 cm, while the lowest height in the H1 variant was 57.8 cm, Kondor in the H2 variant was also 66.2 cm while lower in the H4 variant 62.0 cm, Ultra in the H3 variant also 79.4 cm while lower in the H1 variant 73.3 cm, Carlita in the H2 variant 54.2 cm while lower in the H3 variant 62.6 cm, Arnova in the H3 variant 62.1 cm while the lowest in the H1 variant 56.4 cm or on average all types of potatoes reached the highest height in the H3 variant 65.5 cm while the smallest in the H1 variant was also 62,4 cm. As for the number of tubers per plant of the obtained results, the following was found: Cultivar Desire, the highest number of tubers was reached in the H3 variant (10.3), while the smallest number was in the H2 variant (9.0). , Kondor the highest number of tubers reached the H4 variant (10.0) while the smallest number reached the H3 variant (8.7), Ultra the highest number of tubers reached the H2 variant (8.7), while the smallest number in the H3 variant (7.0), Carlita, the largest number of tubers reached the H2 and H4 variants (10.0), while the smallest number in the H3 variant (9.0), Arnova number the largest number of tubers has reached the H2 variant (10.7) while the smallest number has reached the H4 variant (9.0) or on average all types of potatoes the largest number of tubers has reached the H2 variant (9.5 ) while a smaller number in the H3 variant (9.1).
