| Increasing the yield of spring rapeseed in the conditions of the Central-Chernozem zone of Russia | |

The purpose of the research is to establish the effectiveness of the effect of foliar fertilizing with micro fertilizers in different phases of plant development on the yield and quality of spring rape seeds. The experiments were conducted in 2019 and 2020, in the conditions of the Lipetsk region. Three types of treatments of vegetating plants with micro fertilizers were studied: the rosette phase, the budding phase, the rosette + budding phase. Studied drugs: Microel (0.2 l/ha), Life Force (0.4 l/ha), Boroplus (0.75 l/ha), Plantafol 20:20:20 (1 kg/ha), Plantafol 5:15:45 (1 kg/ha) and Lignohumate (0.15 l/ha). The object of the study was a variety of spring rapeseed Reef. The research was carried out according to the methodological recommendations generally accepted in agronomic science for laying and conducting field experiments. The research results have shown that the most effective are double leaf treatments of plants in the rosette phase and with their further processing in the budding phase. The maximum increase in yield was provided by micro fertilizers Plantafol 20:20:20 and Plantafol 5:15:45 with double treatment, amounting to 2.05 and 1.94 t/ha, respectively, exceeding the control by 0.64 and 0.53 t/ha, respectively. This study allowed us to establish that in the conditions of the forest-steppe of the Central Chernozem region, in order to increase the productivity of spring rapeseed, it is possible to use leaf fertilizing with the studied micro fertilizers.
