Background: The purpose of the research is to study the features of contamination of dark gray forest soils with heavy metals and to establish the yield of oil cabbage crops as a result of the use of various levels of mineral nutrition in the conditions of the Non-black earth zone of Russia. Methods: The experiments were carried out on the dark gray forest soils of Ryazan region in crops of spring rape, white mustard and gray mustard (Sarepta). Soil sampling to determine HMs was carried out before the experiment. Determination of heavy metals was carried out by atomic absorption spectrometry using a semi-quantitative spectral method on a spectrophotometer in the laboratory of the State Station of the Agrochemical Service “Ryazanskaya” and the laboratories of the university. Result: The studied types and combinations of mineral fertilizers had effect on the growth and development of plants. The effectiveness of the use of mineral nutrition doses proves its high efficiency in studies with oilseed crops in the conditions of the Non-Chernozem zone of Russia. The highest yields, for spring rapeseed (19.3 dt ha-1), for gray mustard (13.7 dt ha-1) and white mustard (12.2 dt ha-1), were observed in the variants with the action of N90-120P60K60.

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. Three types of fertilization during oilseed rape vegetative development were studied: a rosette stage, a bud-formation stage, and overlapping rosette + budding stage. The following agrochemical preparations were studied: 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 research results showed that processing foliar fertilization in the rosette stage with further feeding in the bud-formation phase were most effective. Because of 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.

“…Studies proved that the greatest impact on rapeseeds productivity is caused by the norm of nitrogenous fertilizer, while the minor impact is from previous production culture and the fertilizer type, as well as, the interaction between these factors (Rathke and Diepenbrock, 2005). The natural climatic conditions of the central European part of Russia are favorable for growing, not only early-ripening genotypes, but also mediumearly cultivars and hybrids of spring rapeseed as the sum of active temperatures is 2200 °C-2350 °C, and rainfalls measure around 510-560 mm (Ram et al, 2015;Gulidova et al, 2017).…”

Morphological characteristics of Brassica napus pollen (polar axis, equatorial diameter, shape index, pattern of perforation of exines, and perimeter of perforation zones) were investigated by using scanning electron microscopy JEOL JSM-6390. The B. napus seeds were grown under various agroecological conditions, i.e., mineral fertilizer (NPK 60:60:60 t ha-1) separately and together with zeolite, chicken droppings (10 t ha-1) separately and together with zeolite (5 t ha-1), and control (without fertilizers) from 2018 to 2020 at the Bunin Yelets State University, Yelets, Russia. It was found that pollen grains of B. napus had an oblong-ellipsoid shape. In the polar view, the pollen grains were circular with straight sides, though in the equatorial view, elliptical. For the polar axis of the pollen grains in fertilizer application treatments, the minimum values ranged from 24.59 to 27.76 µm, whereas the maximum readings were 40.13 to 42.12 µm compared with control (21.56 µm, 41.52 µm). The coefficient of variation for fertilizer applications ranged from 8.86% to 14.10% compared with control (14.85%) for the polar axis. For the equatorial axis of the pollen grains, the minimum values varied from 11.61 to 15.63 µm, whereas the range for the maximum values was 19.74 to 23.96 µm compared with the control (13.63 µm, 21.88 µm). For the equatorial axis among the fertilizer applications, the coefficient of variation varied from 8.47% to 12.01% compared with the control (18.35%). For the perimeter of the exine perforation of the pollen grains, the minimum values ranged from 1.68 to 1.95 µm, whereas the maximum values varied from 4.34 to 7.12 µm compared with the control (1.34 µm, 5.68 µm). The coefficient of variation varied from 24.48% to 33.19% compared with the control (34.78%) for the perimeter of exine perforation. The shape index of the pollen grains of the B. napus varied from 1.96 to 2.07 µm (correct unit of measure?) compared with the control (2.03 µm). Overall, with the use of organic fertilizers and zeolite, the morphometric parameters of pollen grains were significantly enhanced.
