“…However, in the Akmola Region, these samples showed an average yield of green biomass, this is due to the fact that the thermal resources of the northern part of the studied territory of the country meet the requirements of soft and hard wheat varieties, but are insufficient for sunflower and corn. In the south, heat resources are sufficient for wheat, all sunflower varieties and for medium-late-ripening corn varieties [BAISHOLANOV et al 2018], as well as for sorghum crops. In addition, in the conditions of the Akmola Region, early-maturing sorghum samples do not have time to pass the full cycle of vegetation, and early-maturing do not have time to form full-fledged viable seeds due to early frosts.…”

As the impact of global climate change increases, the interaction of biotic and abiotic stresses increasingly threatens current agricultural practices. The most effective solution to the problem of climate change and a decrease in the amount of atmospheric precipitation is planting extremely drought-resistant and high-yielding crops. Sorghum can grow in harsh conditions such as salinity, drought and limited nutrients, also it is an important part of the diet in many countries. Sorghum can be introduced in many zones of Kazakhstan. Plant height and yield of green plant biomass of 16 sorghum samples in arid conditions were determined based on a set of agrobiological characteristics for field screening. The height of the studied samples of grain sorghum was 0.47 ±0.03 m, and the height of sweet sorghum was much longer, reaching up to 2.88 ±0.12 m. Also, there was a strong difference in green biomass in cultivated areas under different soil and climatic conditions, the green biomass of sweet sorghum was 3.0 Mg•ha -1 , and in grain sorghum, it reached up to 57.4 Mg•ha -1 . Based on the data of the field assessment for various soil and climatic conditions, the following samples were identified for introduction into production: samples of sweet sorghum for irrigated and rainfed lands of the Almaty Region and in the conditions of non-irrigation agriculture of the Aktobe Region -a promising line ICSV 93046. For non-irrigation agriculture of the Akmola Region, genotypes of sweet and grain sorghum are 'Chaika', 'Kinelskoe 4' and 'Volzhskoe 44'.

“…Agroclimatic zoning of the territory of Northern Kazakhstan conducted in 2018 by a group of authoritative experts and scientists on heat and moisture availability showed that the bioclimatic potential of spring wheat yield, i.e., the criterion that characterizes the level of crop yield under natural field moisture and calculated using the computer simulation application "climate-soil-yield", is used in this region by about half (the yield is from 30 to 50 c/ha). Consequently, the level of farming in Kazakhstan is not high enough, especially in comparison with Western European countries, where this figure can reach 85% (Baysholanov et al, 2018).…”

“…At the same time, high atmospheric temperature and reduced rainfall also lead to a decrease in the hydrothermal coefficient and eventually to drought, which negatively affects the agroecosystem: plant growth is sharply reduced, and the development of diseases and pests increases. As suggested by S.S. Baysholanov et al (2018), to measure the level of drought intensity in Kazakhstan, used for many years, a generally accepted indicator in agriculture -Selyaninov's hydrothermal coefficient (HTC), which is calculated for the spring-summer period (May-August) according to the formula:…”

“…It is because of the increase in temperature and decrease in rainfall that climatic zones may shift, for example, a moderately humid moderately warm zone will move to a slightly humid moderately warm zone (Baysholanov et al, 2018). Thus, the assessment of agro-ecosystems on soil moisture supply per the growing season of crops allows for predicting the level of their yield, assessing the reduction of ecological load through a rational selection of crop varieties, optimization of soil treatment methods to reduce moisture loss in the technology of their cultivation, increase the efficiency of the application of fertilizer and plant protection system against diseases and pests, aimed at reducing the ecological load on agro-ecosystems.…”

Spring soft wheat is a primary agricultural crop of North Kazakhstan, the growing process of which is done in harsh weather conditions due to the fact, that early spring drought and the biggest rainfalls at the end of June and beginning of July, are normal in the region. Due to this fact, scientists and producers have mistakenly believed that in the Northern region, spring wheat should be sown later, adjusting the main phase of plant development “tillering – stem elongation” under the maximum summer rainfalls. The research aims to establish the dependence of spring wheat yield on the amount of spring-summer rainfall at different sowing periods. The following methods were used in the research: field method, methods of clustering, variation, correlation and dispersion analysis. Analysis of observations from 2012-2021 showed that years with an early-spring drought and mid-summer maximum rainfalls were less than one-third of ten and about 60% were years with no spring drought, although the maximum rainfall period was shifted to the June month. However, only one year (10%) was characterized by a severe spring drought and a shift of summer rainfalls to August. The highest yield (26.9 c/ha) of the studied wheat species was observed in years with an atmospheric precipitation shift at the beginning of the summer period and early sowing date. During years of early spring drought with the biggest rainfall in mid-summer, relatively high yields (20.5 cwt/ha) are observed in the later sowing dates. The practical value of the research is determined by the fact, that in Northern Kazakhstan the sowing dates of spring wheat are not closely tied to the calendar dates and depend significantly on the climatic conditions of the region and the weather conditions that prevailed in the spring and summer period of a specific year

The article considers the agro-climatic resources of the Republic of Kazakhstan and Central Asia for the period from the beginning of the XXI century to 2021. The spatial distribution of the sums of precipitation during the active vegetation period, the sums of active temperatures and HTC in eastern Uzbekistan, Tajikistan, Kyrgyzstan and southeastern Kazakhstan was studied. Calculated indicators for the allocation of agro-climatic zones of the flat part of Kazakhstan and Central Asia. The zoning of the heat supply during the active vegetation period according to the sums of active temperatures (above 10°C), moisture content according to the sums of precipitation during the active vegetation period, the Selyaninov State Customs Committee, the humidification coefficient (HC), which also takes into account the precipitation of the cold period of the year, was carried out. For the flat territory of Kazakhstan and Central Asia, the nature of the latitudinal and meridional strike of zones and their conditional boundaries is considered. For the study area, 20 agro-climatic zones of heat supply during the period of active vegetation and moisture supply during the year were determined.
