IMPACT OF RAPE SEED DENSITY ON PRODUCTION PROFITABILITY

Abstract

The aim of the study was to compare the profitability of winter oilseed rape with two sowing methods: (row sowing – seed density 60 seeds per 1 m2 and spot sowing – seed density 40 seeds per 1 m2). The yield of rape seed was varied and was at the point sowing – 4.43 t/ha and row sowing – 5.24 t/ha. The income for the tested technologies ranged from 5914.20 PLN/ha (row sowing) and 4231.00 PLN/ha (spot sowing), and the difference was due to the yield of 1 ha. The largest share in the cost structure was the cost of fertilizers (33%), plant protection (27-30%) and machinery (31-32%).
