Abstract

Evaluating the impact of growth regulators is a simple, inexpensive method that is considered an environmentally safe method to improve plant yield and quality, increase growth and productivity.The obtained results of the research on the influence of the Humosteem preparation on the productivity and quality of tomato plants have been presented herein.In foreign countries, 50-80% of tomato crops are treated with such preparations. Their number has been increasing in recent years.Due to the high biological activity of this preparation, it was noted, during the research, that it had a positive effect on local and hybrid varieties of tomatoes during the entire growing season, showed high efficiency in the absorption of nutrients, growth, development and productivity of the plant. It was observed that the content of nitrites and nitrates in plant products did not exceed the state standard requirement. It was determined that the amount of nitrites and nitrates increased by 17.07% in the Yablochniy variety, by 16.5% in the Lojain F1 hybrid, and by 13.3% in the TMK-22 variety under the impact of the Humosteem preparation. Thus, it was observed that the amount of nitrates was low in tomato variety TMK-22.
