MODELING OF THE EFFECT OF SOWING AND SATISFACTION OF GROUND ON GROWTH OF OATS DEVELOPMENT IN THE CONDITIONS OF ODESA REGION

Abstract

Odessa region belongs to the zone with insufficient and unstable humidity conditions for growing a large set of agricultural crops. Ovs belongs to one of the main cereals, whose products are used in many spheres of activity, except for food, feed, as well as in the medical and cosmetic industries. However, in order to obtain high and sustainable crops of this crop in this territory, it is necessary to use irrigation, in connection with the increased requirements of this culture to moisturize. Unfortunately, the water used for irrigation purposes in the Odessa region does not always meet the requirements for its use for irrigation. The main limiting indicators are mineralization and natrium-calcium potential, which are included in the work. In the framework of the work, with the help of a mathematical model that allows predicting the level of possible salinization and soil solubilization, the simulation of the effect of these processes on the growth and development of oats in the conditions of the Odessa region was performed. Calculations were carried out on the basis of field experiment data, which was conducted at the scientific and research station of the ODEKU in the period from 2008 to 2018. The obtained results in the mathematical model are in good agreement with the data obtained with the help of the experiment, therefore they can be used to provide practical recommendations that reduce the negative impact of irrigation on the growth and development of oats in the Odessa region.
