The inoculation of seeds with preparation Rizolain, the combination of inoculation with the bioprotector Rizoseiv, and the spraying of crops with Organic Balance had a significant effect on the height of the plants before harvesting. A significant increase in the area of the leaf surface was due to the factors – spraying of crops with the preparation Organic Balance, seed inoculation with a strain of nodule bacteria in combination with seed treatment with the preparation
Rizoseiv, which is a bioprotector. The largest number of nodules on a soybean plant was noted for the inoculation of Rizolain seeds in combination with the bioprotector Rizoseiv on the background of spraying crops with Organic Balance
– respectively 78 pcs./plant.
The raw mass of active nodules on average in 2021-2022 compared to the control without inoculation and spraying of crops varied according to the experiment options. Thanks to the inoculation of seeds with the drug Rizolain, the number of active nodules and their raw weight increased. The raw mass of nodules increased after inoculation of seeds with the drug Rizolain in combination with the use of the bioprotector Rizoseiv for the treatment of seed material and spraying of crops with the drug Organic Balance and amounted to 8.0 g per 1 plant in soybeans of the Madison variety. Inoculation of soybean seeds also had a significant effect on photosynthetic productivity. The largest area of the leaf surface of the soybean variety was formed in the seed filling phase in the variant with seed inoculation with the drug Rizolain with the simultaneous use of the drug Rizoseiv and spraying of crops with Organic balance – 53.7 thousand m2/ha, in the control it was 49.2 thousand m2/ha.
