Abstract
To obtain high yields of potatoes, plant growth and development regulators of various origins are used. Recently, the use of chemicals made from natural raw materials has become more widespread. One of them is the chemicals Relict based on humic and fulvic acids, which have growth-stimulating adaptogenic and protective properties from peat. It is used both for treatment of tubers before planting, and for vegetative plants treatment. Such treatment allowed to reduce the sparseness in potato plantings, and also contributed to an increase in the yield of large and medium fractions of tubers. The marketability of tubers in the control is 81.7%, and in the areas treated with Relict is higher - at a concentration of 0.01 % - 91.6 %, and by 0.05 % - 93.7 %.
Highlights
Modern intensive agricultural production involves, on the one hand, obtaining the maximum yield of the cultivated crop with minimal costs, on the other-improving the quality of products
Treatment of tubers with the chemicals helped to accelerate the mass regrowth of stems for 2-4 days
The highest height was reached by plants treated with a solution at a concentration of 0.05 %, which exceeded the control by 11 cm, and at a lower concentration by 8 cm
Summary
Modern intensive agricultural production involves, on the one hand, obtaining the maximum yield of the cultivated crop with minimal costs, on the other-improving the quality of products. One of the natural regulators of plant growth and development is the humic chemicals Relict. The chemical acts on cells, and - on plant tissues, it activates bioenergetic processes, stimulates metabolism, improves the penetration of nutrients through the cell membrane, the work of the enzymatic system, increases the stress resistance of plants. The effectiveness of this chemicals increases in the period of sudden changes in weather conditions. The chemicals Relict had a positive effect on the formation of the yield of tubers - an increase in the range of 9-11 is achieved %; 2. There was an increase in the total marketability of tubers, at which the sum of two fractions (large and medium, i.e. (60 + 30 mm) when treated with the chemicals with a concentration of 0.01 % – 91.6 %, and by 0.05 % - 93.7 %
