Abstract
The purpose of the study is to study the aspects of the management of the hydrothermal regime of rice agrocenosis. An assessment of the temperature regime, namely the temperature accumulated by rice sowing, the total indicator of the temperature function «morphogenesis» and the proportion of sunny days for the period from 2010 to 2020, according to the weather station Krasnodar/Kruglik, was carried out. In the course of the analysis, the regularities of the yield value from the temperature factor in different phases of growth and development of rice grown in the climatic conditions of the Lower Kuban were revealed. In the course of the analysis, the regularities of the yield value from the temperature factor in different phases of growth and development of rice grown in the climatic conditions of the Lower Kuban were revealed. So for, the phases of germination, seelings, tillering - with an increase in the sum of high temperatures, the yield increases, for entering the tube and sweeping-maturation - an increase in yield with a decrease in the sum of accumulated high temperatures and an increase in the sum of moderate air temperatures.
