INFLUENCE OF BIOLOGICAL STIMULATORS OF GROWTH AND DEVELOPMENT OF PLANTS ON GROWTH PROCESSES, BIOCHEMICAL COMPOSITION AND PRODUCTIVITY OF MELONES IN THE CONDITIONS OF THE SOUTH-EAST OF KAZAKHSTAN

Abstract

The audience of consumers of watermelon and melon is the widest, the reason for this is the light and at the same time rich composition of sweet fruits. Given the increase in complications among the country's population associated with the postponed coronavirus pandemic, the consumption of highly vitaminized and environmentally friendly products is especially important. Unfortunately, in recent years there has been an acute issue of unfair production of melons and gourds. In pursuit of an early harvest, producers completely forget about quality. Melon products contaminated with nitrates can lead to the most serious consequences. The way out of this situation is to use biological stimulants of the vital activity of soil microorganisms, which accelerates the maturation processes, while reducing the introduction of agrochemicals by almost twice. According to the results of our research, it was found that the treatment of plants with biological stimulants increased the yield of watermelon by 33.88%, melon - 27.30%. Plants treated with bio stimulants were larger, had a greater number of ovaries to control, respectively. Biochemical analysis showed an increase in dry matter, total sugar and ascorbic acid in the fruits of watermelon and melon.
