The aim of the experiment is to study the possibility of growing potatoes with a limited number of soil cultivation, at the beginning of the vegetation. The experiment was conducted at the Vrazhdebna training field of the University of Forestry, on fluvisols. The experiment is laid out according to the growing distance of 70 x 30 cm, with the Soraya variety. The soil cultivation was carried out pre-planting, at the beginning of the experiment and consisted of cultivation at a depth of 20-25 cm and subsequent furrowing at 70 cm between the furrows. During the growing season of the plants, the weed communities in the experiment were recorded, after which the inter-row weeds were mowed. There are two variants - with one mowing and with two mowing of the weeds, with the shredded plant mass being used as mulch. The average yield from one plant with double mowing is 1.428 kg, while with the single mowed option it is 1.015 kg.
