“…Similar results were obtained in a study conducted by L. Prysiazhniuk et al (2023), according to which, the use of ammonium nitrate against the background of phosphorus-potassium nutrition led to an increase in the yield of winter wheat grain by 5-10% compared to only using phosphorus-potassium fertilisers. Therewith, not only the quantity of the crop increases but also the quality of the grain -its size, weight, and protein content.…”

Fertilisation of winter wheat is necessary to provide the crop with nutrients for optimal growth, development, and formation of the crop. However, the effectiveness of fertilisers may depend on their shape, soil conditions, and climate. The purpose of the study is to examine the effectiveness of using various forms of mineral fertilisers on the formation of productivity of winter wheat on grey-meadow soils of Kyrgyzstan. In 2019-2021, field experiment was conducted in the Educational-experimental Farm of the Kyrgyz National Agrarian University, named after K.I. Skryabin to achieve this goal. As a result of the study, it was identified that the formation of high yields of winter wheat is closely related to the use of nitrogen-containing fertilisers in crop rotation, which contributes to the accumulation of nitrate nitrogen in the soil. The substantial effect of ammonium nitrate and granulated superphosphate on the nitrogen regime of the soil was also noted. The concentration of carbon-ammonium-soluble phosphates is determined by the actions of ammonium sulphate, ammonium nitrate, and all forms of phosphorus fertilisers, but no special changes in the phosphate regime of the soil under the influence of forms of phosphorus fertilisers were identified. However, when using complex fertilisers, a slight accumulation of mobile phosphorus in the soil was noted. The introduction of ammonium nitrate ensures the yield of winter wheat grain at the level of 56 centner/ha, ammonium sulphate – 53.1 centner/ha. granulated superphosphate provided the highest level of winter wheat yield – 55.5 centner/ha and the highest increase in yield against the background of nitrogen-potassium nutrition – 8.7 centner/ha. Therefore, for winter wheat, after rowed precursors, it is preferable to apply ammonium nitrate from nitrogen forms of fertilisers. As an alternative to it – ammonium sulphate or urea, from phosphorus forms of fertilisers – granular superphosphate. The practical importance of the results of the study allows for developing more effective methods of using fertilisers and increasing the productivity of grain crops on grey-meadow soils of Kyrgyzstan and in other regions with similar soil and climatic conditions

Purpose. To study of yield formation and protein content in the grain of different ripening varieties of soft winter wheat under the condition of using various types and doses of fertilizers. Methods. Field and laboratory (determination of protein content), calculation (collection of protein), mathematical and statistical. Results. It was found that different fertilization systems reliably increased the grain yield of soft winter wheat. The use of N75 increased this indicator by 1.2 times and N150 by 1.4 times in the varieties studied, compared with the no-fertilizer variant. Yield with incomplete return of phosphorus-potassium fertilizer was only 2–3% lower than with complete mineral fertilizer. With the nitrogen-phosphorus and nitrogen-potassium fertilization systems, the yield was 5–7% higher than with the nitrogen system. At the same time, this indicator was 6% lower than in the full mineral fertilizer version of the trial. The use of 75 kg/ha nitrogen fertilizer per year increased the protein content to 13.5%, or by 10% compared to the control. In the double dose nitrogen fertilizer variant, the protein content increased to 14.2% or by 15%. The use of nitrogen fertilizers with phosphorus-potassium only contributed 2–4% to the increase of this indicator. Cultivation of winter wheat under the condition of application of N75 increased the collection of protein up to 724 kg/ha or by 33%, and with a double dose of nitrogen fertilizer – up to 848 kg/ha or by 55% compared to the option without fertilizer. In the N75P30K40 variant, protein yield increased by 10% compared to the nitrogen system. The application of a complete mineral fertilizer (N150P60K40) increased this indicator by 12%. Conclusions. It was found that the use of N75P30K40 increased the grain yield of soft winter wheat by up to 5.9 t/ha, or 7%, compared to the option where only 75 kg/ha of nitrogen fertilizer was applied. Yield development in soft winter wheat varies considerably from variety to variety. For example, this indicator was 35% higher in the ‘KWS Emil’ variety than in the ‘Prino’ line. In addition, the grain yield of both varieties is reliably influenced by the weather conditions during the growing season. The protein content of soft winter wheat varies considerably depending on the variety and the weather conditions. When growing soft winter wheat varieties, the protein content can vary by 12.8–15.1%. Weather conditions during the growing season can change this indicator by 13.1–14.7%. The protein content index in the grain of the ‘Prino’ line is significantly higher than that of the ‘KWS Emil’ variety. According to the protein yield per hectare indicator, the ‘KWS Emil’ variety (896 kg/ha) has a significant advantage over the ‘Prino’ line (774 kg/ha).

Purpose. To evaluate the quality indicators of spring barley seeds grown under different soil and climatic conditions. Methods. Laboratory, calculation and statistical methods were used during the research, analysis and synthesis methods were used to draw conclusions. Results. As a result of research, the dependence of spring barley quality indicators, namely: grain uniformity and protein content, on soil and climatic zones and growing conditions was revealed. Thus, grain uniformity ranged from 86.7% (high, Polissia) to 95.1% (very high, Forest Steppe) in the different test years. In 2021, thanks to favorable meteorological conditions during the growing season, its indicators increased by 4.3% in the Steppe, 4.6% in the Forest Steppe and almost 6.0% in Polissia compared to 2020. On average, the uniformity of grain grown in different branches of UIPVE increased by 5.6%. The maximum values were obtained for the varieties ‘Avus’ – 93.9% (Steppe), ‘Novyi Svitanok’ – 94.5–96.6% (Polissia, Forest Steppe). Depending on the soil and climate zone and the year of the experiment, the protein content in the grain varied from 10.9 (low, Steppe) to 13.4% (medium, Forest Steppe). On average, this indicator decreased by 2.5% in 2021 compared to 2020, and only in the Polissia zone it increased by 2.6%. The highest protein content was found in the varieties ‘Istr’ – 13.5–13.9% (Steppe and Forest Steppe) and ‘Hercules’ – 13.4% (Polissia). The varieties ‘Amadei’, ‘Istr’ and ‘Novyi Svitanok’ combined both economic and valuable traits. Optimum air temperature and high grain uniformity contribute to increasing the yield of spring barley. At the same time, during the formation of a high yield in the culture, the protein content in the grain decreases. Conclusions. It was revealed that, on average, in 2020–2021, the uniformity of spring barley grain was 92.3% (Steppe), 95.4% (Forest Steppe) and 93.2% (Polissia); the protein content in the grains was 11.8% (Steppe), 12.4% (Forest Steppe) and 11.6% (Polissia). The formation of quality indicators of spring barley seeds was influenced by the growing conditions in the relevant soil and climatic zone.
