THE ECONOMIC ASSESMENT OF PRODUCTION TECHNOLOGY OF HARD WHEAT DEPENDING ON THE PRODUCTION INTENSITY LEVEL

The aim of the study was to assess the production and economic effects of spring wheat cultivar SMH87 depending on the intensity of production technology. The analysis was based on research conducted in 2013-2014 at the Experimental Station in Osiny belonging to the Institute of Soil Science and Plant Cultivation - State Research Institute in Pulawy. Wheat was grown using the following production technologies: medium-intensive and intensive. The studied technologies differed in the level of mineral fertilization and chemical plant protection against weeds, diseases, and pests. The studies showed a significant influence of the production technology intensity level on durum wheat yielding. Durum wheat cultivated under intensive technology yielded higher than under the average level of agrotechnics. However, a significant increase in grain yield was observed in the harvest year 2014, amounting to 1,07 t.ha-1. The lowest direct costs were incurred with the use of medium-intensive technology, while the highest in intensive technology conditions. The difference in direct costs resulted primarily from the reduction of consumption of mineral fertilizers and reduction of plant protection treatments under the integrated technology compared to the intensive technology. The highest direct surplus from 1 ha of durum wheat cultivation was obtained with the use of intensive technology in 2014 (PLN 3696 ), which was 18.7 % higher than the average intensive technology. The profitability of durum wheat production in every technology was high. The most favourable direct profitability index was obtained by durum wheat cultivated according to medium-intensive technology.
