Economic efficiency of growing common bean (grain) in the western Forest-Steppe conditions

Purpose. To establish the economic efficiency of growing common (grain) beans depending on varietal characteristics, fertilization and seed inoculation. Methods. Field – to record grain yield; calculation – to determine the cost of production, net profit and level of profitability; statistical – for mathematical processing of yield data using the method of variance analysis. Results. The maximum impact on the level of economic efficiency of bean grain production had the cultivar. Thus, against the background of the application of mineral fertilizers at a dose of N32P32K32, the yield of beans in the cultivars ranged from 1.33 to 2.45 t/ha. Accordingly, with a selling price of bean grain of 28 UAH, the lowest cost of the resulting product was for the Galaktika variety – 37,24 UAH. The maximum cost of production from 1 ha of bean crops was provided by the Ros, Nata and Otrada cultivars – 64.96, 67.48 and 68,6 UAH, respectively. Due to the increase in bean yield in the variant using biological preparations for seed treatment, the level of profitability increased by 0.8- 9.7%. Carrying out two foliar top dressings with potassium humate increased the conditional net profit when growing the Nata and Slaviya varieties by 3099 and 3106 UAH/ha, and the profitability level by 6.7-7.4%, respectively. The increase in the cost of production from 1 ha was more significant when combining seed treatment with Rizoaktiv + Rootella biological preparations and carrying out two foliar top dressings of crops with potassium humate. The combination of these types of fertilizers in the common bean nutrition system ensured an increase in the cost of the resulting product by 3080-7560 UAH/ha, or 5.4-11%. Conclusions. Growing grain beans is profitable. The Ros, Nata and Otrada cultivars have the greatest impact on yield and economic efficiency, especially when treated with Rizoaktiv, Rootella biological preparations and fertilized with Gumifield.
