Field polyfactorial trials were carried out in a warm corn production area of Slovakia with three spring barley varieties Annabell, Kompakt and Nitran and two newly-breads KM 2010 and KM 2092, after sugar beet in three repetitions. We were monitoring four methods of soil cultivation: A - conventional soil cultivation-tillage up to 0.18-0.20 m with ploughing under the harvested remains, B - conventional soil cultivation-tillage up to 0.18-0.20 m without ploughing under the harvested remains, C- minimizing soil cultivation - (depth to 0.12-0.15 m) with ploughing under the harvested remains; D - minimizing soil cultivation - (depth to 0.12-0.15 m) without ploughing under the harvested remains; Variety Annabell achieved the highest average yield amount with its 5.97 t per ha, it also achieved the highest number of plants and spikes. The differences in crops of weed and naked varieties within particular years/classes ranged from 0.62 t per ha to 1.56 t per ha in favour of haffy varieties. The highest crop we noticed when using minimizing soil cultivation without ploughing under the harvested remains (C way of soil cultivation) (5.69 t per ha), when using this method we also noticed the highest number of plants (233 pcs per square m) and spikes (577 pcs per square m).
