THE ECONOMIC ASSESMENT OF PRODUCTION TECHNOLOGY OF WINTER RYE WITH DIFFERENT INTENSITY LEVEL

The aim of the research was an evaluation of production and economic effects of cultivation of two winter rye cultivars, depending on the applied technology. The paper was based on the results of a field experiment carried out in 2013/2014 and 2014/2015 in the Kepa Agricultural Experimental Station, belonging to the Institute of Soil Science and Plant Cultivation - State Research Institute in Pulawy (Poland). The cultivars tested are: Dankowskie Diament - population cultivar and Palazzo - hybrid cultivar. Rye cultivars were grown under two technologies: intensive and integrated technologies, which differed in terms of the degree of consumption of the means of production. The studies showed a significant influence of the production technology intensity on the yields of winter rye cultivars. In comparison with integrated technology, rye cultivation according to intensive technology, resulted in an increase of grain yields for hybrid cultivar Palazzo by 0.97 t.ha-1, and for population cultivar Dankowskie Diament by 1.26 t.ha-1. This increase of yield resulted from a decrease in direct expenditures related to the use of mineral fertilizers and chemical plant protection agents. Studies have shown that the level of technology intensity calculated by input costs, determined the structure of direct costs and cost-effectiveness of production. Comparable technologies have ensured the profitability of winter rye grain production. The hybrid cultivar Palazzo grown according to the integrated technology, was the most advantageous indicator of direct profitability.
