INFLUENCE OF TERMS AND RATES OF BIOSTIMULANTS APPLICATION ON THE DYNAMICS OF LEAF DEVELOPMENT IN MUNG BEAN VARIETIES

Abstract

This article studies the effect of the timing and rates of the use of biostimulants (Phytobiosol, Gumi-20, Avangard Start) on the development of leaves in mung bean varieties "Durdona" and "Marjon". Experimental work was carried out in 2022–2024 at two planting densities (200 and 300 thousand plants/ha). According to the results of the experiment, the largest number of leaves (16.5 pcs.) was recorded in the variety "Durdona" when treated with the biostimulant Avangard Start at a planting density of 200 thousand plants/ha the number of leaves. The positive effect of biostimulants activated the growth of leaves, which confirms their importance in the development of effective agricultural technology.
