“…In case of early sowing in insufficiently heated soil, field germination of seed material decreases to 40 percent, the number of dead seeds increases sharply, the period of germination of survivors increases to 20-25 days, and seedlings are obtained thinned. At the same time, it is not recommended to be late with the sowing of Sudan grass, as in this case the seeds enter already dry soil, which also delays their germination (Bondarenko and Kopyrin, 1985;Zherukov et al, 2006;Kapustin, 2019) An important point is the choice of sowing term. Seeds begin to germinate at soil temperature at the depth of their coverage 5-8°С.…”

Sudan grass (Sorghum sudanense (Piper.) Stapf) for the dry-steppe zone of West Kazakhstan is the most productive and drought-resistant, as well as promising culture. Therefore, in order to ensure the smooth supply of feed to livestock, it is important to carry out studies on the adaptation of elements of Sudan grass cultivation technology to the regional conditions. The research examined different sowing times at 10-day intervals, and for the harvesting of green fodder, haylage and hay, the harvesting times were examined in different phases of development, as well as grazing mode of use of Sudan grass. The results of scientific research showed that for the conditions of the region it is important to select both optimal sowing and harvesting times. In the years of research, the yield of dry mass of Sudan grass at different sowing times was 21.05-23.37 c/ha, with the highest productivity determined at 1 early sowing time. When studying the time of harvesting, high yield of dry mass of Sudan grass was ensured during harvesting of plant formations in the blooming period 19.06-23.69 c/ha. Under grazing conditions in the study area, Sudan grass produced 16.99 c/ha of dry mass in a total of 4 browsing.

Abstract. The purpose is to assess the adaptability of sugar sorghum genotypes in various agro-climatic zones of cultivation. Methods. The reaction rate of 8 samples of sugar sorghum selected by Russian Research and Design-Technological Institute of Sorghum and Corn was evaluated based on the results of the 2020–2022 test in two ecological points: Saratov (Russia, Saratov region) and Kokshetau (Kazakhstan, Akmola region), characterized by different climatic conditions. Methods of cultivation of plants, accounting for yields are generally accepted for sorghum. The repetition in the experiment is threefold, the placement of plots is randomized. Results. According to the results of statistical analysis, the share of the studied factors in the overall variability of traits was established: the greatest contribution to the “plant height” and “biomass yield” was made by the factor “ecological testing point” (33.6–58.0 %), in the “area of the largest leaf” – “genotype” (31.3 %). It was found that in the conditions of Northern Kazakhstan, characterized by lower heat and moisture availability during sorghum testing (the difference in the sum of active temperatures reached 466.2–769.9 °C, and precipitation – 17.0–106.1 mm in comparison with the conditions of the Lower Volga region of Russia), the area of the largest leaf increased by 10.6 cm2 on average for the group of genotypes studied at the same time, the height of plants and the yield of vegetative mass decreased by 22.2 cm and 11.26 t/ha, respectively. At the same time, varieties and hybrids have been identified that form a biomass yield of 20.54–21.44 t/ha on average during the test period – Chayka, Volzhskoe 51, Sakhara, Kalibr. Scientific novelty. For the first time, the possibility of growing varieties of sugar sorghum selected by Russian Research and Design-Technological Institute of Sorghum and Corn in the conditions of Northern Kazakhstan is presented. Thus, according to the complex of adaptability parameters in combination with high biomass productivity, on average, the Volzhskoe 51 variety was selected for the points of environmental testing.
