Effect of fertilizers for Phaseolus vulgaris L. productivity in Western Forest-Steppe of Ukraine

The scientific article summarizes the improving the efficiency of growing legumes by selecting varieties, primary tillage mode, and optimization of plant nutrition in the Western Forest-Steppe. Studies have shown that legumes are the most demanding crops. In the Western Forest-Steppe, the Bukovynka variety of legumes became more productive when inoculating seeds with Rhizobophyte, applying mineral fertilizer (N30P60K60), foliar fertilization of crystallin, the grain yield of legumes was 2.69 t/ha. A high correlation is observed between the number of beans and the number of grains per plant (r = 0.98), the mass of grains from one plant and the mass of 1000 grains (r = 0.97), number of grains per 1 plant, and the mass of grains per plant (r = 0.96). The moderate correlation was between the number of grains in the bean (r = 0.63) and the weight of 1000 grains (r = 0.66). A low correlation (r = 0.45) was observed between the number of beans per plant and the bean's number of grains. Negative correlations we registered for the number of beans per plant and a mass of 1000 grains (r = -0.37) and the number of grains per one plant (r = -0.17). Thus, we revealed the Bukovynka variety provided the highest level of legume grain yield during inoculation of seeds with Rhizobophyte, applying mineral fertilizer at the dose of N30P60K60, and two foliar fertilization of crops with Kristalon.
