The research was carried out over 2004-2006 at the Experiment Station Osiny (51°28’ N; 22°04’ E) of the Institute of Soil Science and Plant Cultivation – PIB in Puławy. Three technologies of cultivation of winter wheat cultivar Sukces, winter triticale Kitaro and spring barley Stratus, differing in the level of consumption of industrial means of production: economical, moderately intensive and intensive, were taken into consideration. Each grain species was sown on 1 hectare area in which three parcels differing in technology intensity were separated. Production technologies applied influenced grain yielding and economic efficacy. Winter wheat and winter triticale yielded the best under moderately intensive and intensive technologies, but the biggest direct surplus was obtained under moderately intensive and economical technologies. On the other hand, the input intensification of spring barley production did not change significantly grain yielding, which resulted in the highest direct surplus under economical and moderately intensive technologies.
