The yield of pea varieties when using an inoculants

Currently, it is very important to increase the production of vegetable protein by expanding the acreage of grain and legume crops. One of the most common grain legumes is peas. The research is devoted to studying the effectiveness of the inoculant when growing peas on gray forest soils. The inoculation method is used to activate the symbiosis of a cultivated plant and nitrogen-fixing bacteria. The article proposes studies to determine the effectiveness of the Planteco pea RL inoculant, in various doses, on peas. Experiments were carried out on two varieties Roket and Osanato, on dark gray soils of the Ryazan region in 2021-2022. In the process of monitoring crops treated with inoculant, there is an improvement in photosynthesis, plant survival for harvesting, crop structure, and yield compared to the control (without inoculant treatment). According to the research results, it was revealed that variants with an inoculant at a drug rate of 4 kg/t increased the total plant weight of the Ostinato variety by 108.1%; 3 kg/t - by 96.0%; 2 kg/t - 62.2% of control. The weight of beans at an inoculant rate of 4 kg/t is 57.3% greater than the control; 3 kg/t - 63.0%; 2 kg/t - 13.3%. In the experiment, the highest average yield was obtained with the treatment of Planteco pea RL seeds, 4 kg/t, for both the Rocket and Ostinato varieties (1.68 and 2.19 t/ha, respectively). Based on research results, it is recommended to use the Planteco pea RL inoculant in the production technology of peas for seeds in the conditions of the Ryazan region, as an effective environmentally friendly method.
