Yield and quality of winter oilseed rape in response to different systems of foliar fertilization

From 1970 to nowadays, breeders have improved oilseed rape (Brassica napus) in many ways: creation of double low varieties (free of erucic acid and with a low content in glucosinolates), increase of the seed yield and quality of seeds and improvement of resistance to diseases. All this work helped oilseed rape to become one of the most produced oilseed crop in the world. However, this intensive breeding on quality has reduced the genetic diversity of winter oilseed rape. In this study, a group of four breeding companies (RAGT, Limagrain, Syngenta, Euralis) called “GIE Colza” has been working with INRAE (National Research Institute for Agriculture, Food and Environment, France) on the FSRSO project “Printiver”. This project aimed at enlarging the genetic variability available in winter-type oilseed rape through crossing with spring-type materials to create lines with a winter-type behavior (need of vernalization) and a genetic background that has introgressed spring-type genetic diversity. Two pools have been created and selected for their need of vernalization, date of flowering, yield and other agronomic traits. The Group tested these two pools in multilocal trials. The results show interesting per se value and combining ability.

Purpose. Revealing the dependence of the formation of high yield and quality indicators of winter seeds on the influence of the level of intensification of the cultivation technology in the conditions of the Forest-Steppe of the Right Bank. Methods The results of the conducted researches on the influence of the sowing method, sowing norms of winter rape on its seed productivity are given. The prospect of expanding the sown areas of winter oilseed rape, actualizes research to identify the dependence of the formation of high yields and quality indicators of winter oilseed rape from the influence of the level of intensification of cultivation technology. The research methods used in the field experiment correspond to the methods of field experiments and guidelines. The experiment was established by the method of split sites. Winter rapeseed cultivar Antaria of Ukrainian selection and Exagon hybrid of foreign selection were used for sowing. The generally accepted technology of growing winter rape for the area where the research was conducted was used. Results. The results of the research on the influence of sowing method, sowing norms of winter oilseed rape on its seed productivity show that the highest yield of winter oilseed rape seeds was obtained by sowing ordinary row with a row spacing of 15 cm, and sowing rate in the variety - 0.8 million seeds /ha, hybrid - 0.6 million seeds / ha. It is established that the method of sowing and sowing norms affect the quality of winter rape. The optimal sowing rate of winter rapeseed is for the variety - 0.8 million similar seeds per 1 ha, for the hybrid - 0.6 million similar seeds per 1 ha, when sown in the usual row method with a row spacing of 15 cm. Conclusions. It was found that the highest oil content in winter rapeseed was - 46.98% for sowing in a wide row with a row spacing of 45 cm. Also, this method of sowing was determined by the lowest (0.39%) content of erucic acid, while the content of glucosinolates for this method of sowing was higher (33.1 μmol / g) compared to the usual method of sowing.
