In the article, the results of the analysis of the transition of the development stages of plants,growth intensityand productivitydepend onthelivingconditions. Key words: plant, dry mass, biomass, productivity, development, air temperature, relative humidity. The value of the biomass produced at a certain period of plant development is an important integral indicator of the efficiency of the production process. As a result of selection, the final value of the grain yield indicator does not change significantly, and the increase in grain yield is achieved mainly due to the more efficient use of assimilation for replenishment [1]. The passage of plant development stages, growth intensity and productivity depend to a certain extent on living conditions. Plants develop best with optimal provision of all necessary life processes and high-quality implementation of all agrotechnical measures [2]. The occurrence of drought in the soil with a decrease in moisture content leads to high air temperatures during the formation of spikes in grain plants, damage to flower buds, termination of spike formation and their drying out. As a result, the number of grainless spikes increases. For many plants, high air temperatures are especially dangerous during their flowering period, leading to flower shedding, node failure, and sterility. The process of dry mass accumulation continues until the plant belt completely exhausts the chlorophyll grains in its belt and leaves. [3]. The plant begins to grow strongly from the moment of flowering. Therefore, this period in the life of plants is considered the most responsible, that is, the “critical period”, when it is sufficiently supplied with water and nutrients. Wheat yield was, to a certain extent, directly dependent on physiological conditions during the tillering period, and on the level of nutrient andmoisturesupply [4].

The highest dry mass in the tuberization phase of the Karasnodarskaya-99 variety was observed in the foothills, averaging 281.2 g/m 2.It produced 10.2 g/m 2more dry mass in the Karshi district and 53.7g/m 2moredry mass in theKasbi district. that the dry mass of winter wheat reached the wax ripening phase, and the average dry mass obtained from 1m 2in the desert regionswas 1076.8 grams, in the semi-arid regions it was 1285.8 grams, and in the foothills it was 1322.1 grams. This proves that the soil-climate region ofthefoothillsis favorable fortheaccumulation ofplant biomass.
