Abstract.
In the article, the results of the analysis of the transition of the development stages of
plants, growth intensity and productivity depend on the living conditions.
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
and moisture supply [4].

Among the varieties studied in our study, the average yield of the Yaksart variety in
the Kasbi district, located in the desert region, during the accumulation phase was 112.1 g/m

.
ha, 130.8 g/m

in the Karshi district, and 130.8 g/m

in the Shakhrisabz region , which can be
explained by the fact that the wintering efficiency of plants in the desert region was lower than
in other regions (see Table 3.4.1).
The highest dry mass in the tuberization phase of the Karasnodarskaya-99 variety was
observed in the foothills, averaging 281.2 g/m

It produced 10.2 g/m

more dry mass in the
Karshi district and 53.7 g/m

that the dry mass of winter wheat reached the wax ripening phase, and the average dry
mass obtained from 1m
2
in the desert regions was 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
of the foothills is favorable for the accumulation of plant biomass.

According to the results of the research, the amount of dry mass per 1 hectare in Kasbi
district during the accumulation period is 10.8 tons. ni, 23.9 ts in the tube phase. ni, 86.1 ts in
the spike phase. ni, 97.7 ts in the flowering phase. ni, 107.7 ts in the wax ripening phase. , and
as the plant developed, the amount of dry mass increased (see Table 2).
The increase in dry mass after the wax ripening phase almost stops. This is due to the fact
that the plant, which has entered the grain ripening phase, stops developing. In short, drought in
the atmosphere, combined with high temperatures and intense sunlight, stops the growth of the
stem and leaves of the plant. Taking into account hereditary characteristics when selecting
varieties for each region allows you to maximize the yield and technological quality indicators.
It is effective to plant Yaksart and Turkestan for the desert area of Kasbi district, Ghozgan and
Yaksart for the sub-desert soil-climatic conditions of Karshi district, and Krasnodarskaya-99,
Selyanka and Ghozgan for the Shakhrisabz district with sub-mountain soil-climatic conditions
and use them as a starting source for creating new varieties.
A decrease in productivity occurs due to the delay in harvesting operations, drying of
grains in the ear, mechanical losses and spillage, and damage to the grain. When analyzing the
cross-section of the varieties, it was found that the locally created Gozgon variety has a high
yield in the middle-Karshi district of the province due to its high resistance to heat and drought,
and due to its intensity, while the Krasnodarskaya-99 variety has low yield due to its lack of
resistance to heat and drought.
In conclusion, the arrival of spring season in Kashkadarya region (rainfall is similar to
long-term average indicators), sufficient relative humidity of the air and the formation of crop
structure in the flowering-grain filling season is the reason for a high yield. A decrease in
productivity occurs due to the delay in harvesting operations, drying of grains in the ear,
mechanical losses and spillage, and damage to the grain. In the mountainous regions of the
Kashkadarya region, the varieties belonging to the Krasnodar selection can give a high yield,
and in the middle and desert regions, a higher yield can be grown than the local varieties.
