Abstract. The research aimed to study the effect of Ultramag Combi microfertilizer for oil crops on the yield and quality of spring rape oilseeds. The work was performed in 2018–2019 under conditions of the Kansk forest-steppe of the Krasnoyarsk Territory. The experimental design included the following treatments: genotype (factor A) – variety Sibirsky, hybrid Solar KL; micronutrient fertilizers (factor B) – without microfertilizers, microfertilizer Ultramag Combi for oil crops in the budding phase (2 L/ha). The soil of the experimental field was leached chernozem. Nitrogen availability was low; mobile phosphorus availability was very high; potassium availability was medium. The seeding rate was 0.7 million germinating grains per hectare. When cultivated, rape plants were comprehensively protected against pests, diseases, and weeds. The harvest was counted in the phase of full ripeness of the seeds. The use of Ultramag Combi for oil crops increased the viability before harvesting of Sibirsky rape variety by 4–6%; for Solar KL hybrid, it increased by 6–8%, in relation to the control. The mass of 1,000 grains in the option with micronutrient fertilizers for Sibirsky variety increased by 8%; for Solar KL hybrid, it increased by 4–7%. Ultramag Combi top dressing for oil crops increased the oilseed yield of Sibirsky spring rape variety on average over the years of the study by 29%; for Solar KL hybrid it increased by 25%. Fertilization increased the seed yield of spring rape by 13–40%. Microfertilizers did not affect the content of fat and protein in rapeseeds, but increased oil yield per unit area by 24.0–31.4% and protein yield by 27.9–35.3%.
Keywords: spring rape (Brassica napus L.); variety; hybrid; Ultramag Combi for oil crops; foliar feeding; oilseeds; yield; plant viability before harvesting; weight of 1,000 seeds.
