Micronutrients in rapeseed crops

Abstract

Trace elements are involved in almost all processes of plant life, despite the fact that they need very small amounts. The lack of trace elements in the soil does not lead to the death of plants, but is the cause of a decrease in the rate of their development. In the end, the plants do not realize their capabilities and give a low and low-quality crop. To solve this problem quickly, you can use foliar fertilizing with microfertilizers. The purpose of this study was to assess the impact of foliar fertilizing at different times with new types of complex microfertilizers on the productivity of spring rapeseed and the quality of its oilseeds. The experiments were carried out in the Lipetsk Region in Russia in 2019 and 2020 on Rif spring oilseed rape variety. The research results showed that processing foliar fertilization in the rosette stage with further feeding in the bud-formation phase were most effective. Because of 360 the provision with microelements, vegetative plants were able to synthesize a full complex of enzymes. Plantafol 20:20:20 and Plantafol 5:15:45 micronutrient fertilizers provided the maximum increase in the rapeseed yield with double-spray processing, yielding 2.05 and 1.94 t/ha, respectively, and exceeding the control crops by 0.64 and 0.53 t/ha, respectively. Цель исследования - установить эффективность влияния внекорневых подкормок микроудобрениями в разные фазы развития растений на урожайность и качество семян ярового рапса. Опыты проводились в 2019 и 2020 годах в Липецкой области (Центрально-Черноземная зона России).
