Abstract

To assess the quality of humic fertilizers, it is necessary to conduct research on their effects on the growth and development of crops. But for a comprehensive analysis of the influence of the investigated factors, it is expedient to have a mathematical model of the process, for example, in the form of a regression equation. This equation can be obtained by applying the mathematical experiment planning method.
Therefore, the purpose of this study is to obtain a mathematical model of the influence of sapropel humates made in a continuous mixer on the growth of radish radish in the process of vegetative experiment.
A technique was developed for determining the influence of sapropel humates on the growth of agricultural crops based on the use of the plan for implementing the second-order Boxes-Benkin experiment, which allows obtaining a mathematical model of the process of the form of a regression equation. The response function of the obtained equation is the plant height at day 10 after sowing.
Analysis of the obtained regression equation shows that all investigated factors have a significant effect on the growth of the radish, but not the correlation between them, since all the effects of pair interaction were statistically insignificant. Also, an active increase in the growth of the vegetable radish mass of the oilseed during the introduction of hams of sapropel in the range of 10-12 t / ha and the concentration of alkali used for the preparation of humates within 3-4%.
