The effectiveness of applying mineral fertilizers in the cultivation of green bean for seeds

Abstract

Abstract Growing beans is one of the main ways to increase the production of vegetable protein. The problem of implementing high seed productivity of vegetable bean varieties while maintaining the high quality of the produced seeds is relevant. Increasing the yield of seeds and improving their quality is possible due to the scientifically based use of mineral fertilizers in the cultivation of beans. Optimal rates and the ratio of nitrogen, phosphorous and potash fertilizers allow getting a significant increase in the yield of high-quality seeds. On sod-podzol medium-loamy soils, the optimal rate of mineral fertilizers for green beans and Cinderella varieties was N30P45K45. There was an increase in the total protein content under the influence of mineral fertilizers by 0.2-2.0% in the Cinderella variety and by 0.5-1.8% in the Lika variety. The use of optimal mineral fertilizers in the cultivation of green beans provided a net income for the Lika variety 122.2 thousand rubles/ha and the Cinderella variety – 117.4 thousand rubles/ha.
