On the basis of the results of three-year field trials performed on pseudogley illimerized soil, the influence of some cultural pracitices on the yield of winter wheat grain was evaluated. All the three varieties studied negatively responded to a delayed sowing (at late sowing, the yield of the Kosutka variety was lower by up to 12.3 per cent). The amount of seed sown was not a significant factor of intensification. Both the Agra and Roxana varieties were able to offset the studied differential range of 3.0 million germinative grains per ha. The Kosutka variety reacted adversely to the decrease in the sowing rate. Nitrogen application rate on the higher level tested (120 kg per ha), divided into two batches, proved to be optimum in the given region when wheat was grown after silage maize as forecrop. The sequence of the surveyed factors with their effect on the grain yields was as follows: year, date of sowing, variety, nitro fertilization, sowing rate.
