Ways to increase bean productivity and quality with different growing technologies

The aim of the research was: to study ways to increase the productivity of beans by combining in a single process fertilizer, pre-sowing seed treatment with drugs based on an active strain of nodule bacteria, growth stimulants of biological origin, micronutrients in the form of negligence. Methods. The research program included: phenological observations of plant development (development phases and stages of organogenesis), morphological - on the formation of elements of productivity, leaf apparatus and duration of its functioning, morphophysiological - on the dynamics of development of productivity elements, the formation of productive potential. Results. The article presents the results of research on the effectiveness of mineral fertilizers, growth stimulants and microfertilizers to increase the productivity of beans and its quality. It is established that the maximum yield of beans - 2.81 t / ha (in 2018 3.30 t / ha) at the level of absolute control, respectively 1.05 t / ha was formed on the option, which involves the application of mineral fertilizers at a dose of P60K60 + N30 + N30 kg / ha d.r., sowing of seeds treated with a strain of nodule bacteria BTU - p and joint treatment of crops with growth stimulants in the physique of branching and budding with microfertilizers in the budding phase. The maximum increase in yield was 0.92 t / ha, and 0.86 t / ha from the application of fertilizers was obtained with the application of P60K60 + N30 + N15 and P 0 K0 + N30 + N30, with the control of 1.05 t / ha. Pre-sowing inoculation of seeds with a strain of nitrogen-fixing bacteria BTU-r provided an increase in yield - 0.24 - 0.39 t / ha. The use of growth stimulator in the technology of cultivation provided an increase in crop productivity by 1.04 t / ha on the background without seed inoculation, with inoculation - 2.22 t / ha compared to the absolute control (1.05 t / ha). Co-application of growth stimulant with microfertilizers on crops yielded 2.41 t / ha with a protein content of 20.39%.
