Study of imidazolinone-resistant hybrids of rapeseed and sunflower for yield depending on doses of mineral nutrition

The article offers an analysis of the yield of hybrid lines of sunflower and spring rapeseed, grown according to the technology using herbicides of the chemical class Imidozalinones, against the background of various doses of mineral nutrition. The research was carried out in two regions of the Central European part of Russia, in the Lipetsk and Ryazan regions in 2021-2022. According to the results of the experiment, all used hybrids of oilseeds showed high yields, above the average yields for the regions. The maximum yield was found in all plots of mineral nutrition with the action of N 250 P 70 K 70 - for sunflower, and with the action of N 210 P 50 K 50 - for spring rapeseed.
