Study of the symbiotic activity of mung bean (Phaseolus aureus Piper.) varieties under meadow-swamp soil conditions

Abstract

The article describes the researches conducted on the influence of planting periods and norms on the development of tubers in mung bean varieties in the conditions of irrigated meadow swamp soils. Planting norms and periods significantly affected the symbiotic activity of mung bean varieties. It was found that the development of tubers in mung bean varieties decreased as the planting rate increased, compared to the spring planting period, the symbiotic activity of the varieties was mainly high when it was planted on June 20, and it was weak when it was planted in July.
