Abstract

Abstract Ryazan Agrotechnological University. P.A. Kostychev, the biocatalytic properties of highly dispersed humic acids (HHA) on various crops are being studied, but the question of the influence of HHA on ornamental crops has not been studied at all. A laboratory experiment on seeds and seedlings of Tagetes patula L. (variety “Makkeny’s Gold”) showed that for the seeds of this crop, the most effective concentration of HHA is 5.0 g/t, which increases germination, the length of the sprout by 2.5 mm (+9.5 %) and root by 3.8 mm (+20.9%), as well as the weight of the sprout by 36.7% and root by 55.9% relative to the control. An experiment on vegetative plants Tagetes patula L. showed that a dose of HHA of 5.0 g/t increases the decorative qualities of this crop, so there was an increase in plant height by 5.1 cm (+21%) and root system weight by 1.3 g ( + 25.5%), the number of leaves per 1 plant increased by 5 pcs (+14.7%), the number of flowers per 1 plant increased by 1.9 pcs (+25%), as well as the flower diameter by 0.9 cm ( +15.3%) relative to control. HHA at a dose of 6.0 g/t most effectively influenced the speed of the vegetation phases, reducing the period from germination to the beginning of flowering by 6 days. Also, when using HHA 6.0 g/t, the maximum seed productivity of Tagetes patula L. was determined, the weight of seeds from 1 plant was 5.3 g, which is higher than the control by 0.8 g (+17.8%).
