The results pointed out a positive influence of shallow soil cultivation and optimalized nitrogen dose on grain yield of winter barley. Two varieties (Luxor and Hanna) reacted significantly on shallow soil cultivation (disc tiller, var. C), where was reached a higher increase of yield from 0.26 to 0.31 t/ha in comparison to conventional cultivation. Babylone variety obtained the highest grain yield on conventional cultivation with an increase by 0.43 t/ha in comparison to shallow soil cultivation. Higher values of KEE from 4.51 to 5.8 and nutrient rate 1 : 0.65 : 1.66 were found out on variant with total dose of nitrogen 40 kg/ha. Multirowed Luxor variety reached an increase by 1.02 t/ha and by 1.18 t/ha compared to two-rowed varieties Hanna and Babylone. It is evident, from proportion of agrotechnical components, that an yield increase was influenced by variety (23%), cultivating methods (31%) and fertilisation (46%)
