Popis: An experiment with different variants of weed control in the maize crop was carried out in 2021 at a location next to the Markovo Polje settlement on silty loam soil. Three variants of weed control were applied: 1. mechanical weed control between the maize rows with a motocultivator and manual hoeing within the rows, 2. mechanical weed control only between the maize rows with a motocultivator without control within the rows, 3. without any control of weeds. In the experimental field, 14 different types of weeds were found, of which Amaranthus retroflexus, Ambrosia artemisiifolia, Chenopodium album and Sorghum halepense prevailed. As expected, the lowest weed infestation of the experimental plots was on the plots where variant 1 of weed control was applied, in variant 2 the average mass of weeds per 1 m2 was 223%, and in variant 3 it was even 334% higher compared to variant 1. Maize yields were inversely proportional to the weed infestation of the experimental plots, the highest yields were achieved in variant 1 with an average of 6015 kg ha-1, in variant 2 the average yield was 2907 kg ha-1, and in variant 3 1242 kg ha-1. The combination of mechanical weed control and manual hoeing can be an alternative to the use of herbicides on smaller family farms and in organic maize production.
