Fertilizers effect on the chemical composition of vegetable beans

The article presents the results of studies on the change in the intensity of accumulation of nutrients in seeds, in the trunk, root and leaves of green beans, depending on the phase of plant development. The change of indicators of nitrogen availability in the branching phase was 1,05-1,61%, phosphorus 0,79-1,25, and potassium 1,30-1,92%; in the flowering phase respectively 0,84-1,28%; 0,44-0,87%, and 0,95-1,35%; during the period of beans formation: nitrogen 2,26-2,93%, phosphorus 0,85-1,54%; potassium 1,17-1,65%; in the phase of seed formation, respectively 3,51-4,03%; 0,74-1,01%; and 0,86-1,07%. It was revealed that the effectiveness of the use of organic and mineral fertilizers directly depends on the degree of soil fertility, on the phases of plant development during the growing season and other environmental factors.
