“…The study of the effect of different doses of mineral fertilizers, their forms, and methods of application is relevant for increasing the yield of rice and the quality of the resulting products, since high doses of fertilizers are not always the key to maximum nitrogen uptake by plants, and low doses are not sufficient to increase their yield. The efficiency of nitrogen assimilation depends on the varietal characteristics of rice, climatic conditions, the growing season of plants and combination with other macronutrients, which should be taken into account when growing a crop [52][53][54].…”

The purpose of this research is to study the effect of doses of nitrogen fertilizers and methods of their application on the development and yield of rice plants of the Syr Suluy variety in the Kyzylorda region of the Republic of Kazakhstan. To study the effectiveness of methods for applying nitrogen fertilizers, options for their fractional application were provided at a rate of 120 kg/ha and 150 kg/ha. The ammonium nitrogen in the soil and the intensity of dry matter accumulation during the vegetation phases were analysed. The biometric parameters of rice plants were also studied, and the yield was estimated. Increasing the dose of nitrogen fertilizers led to increased accumulation of dry matter throughout the various phases of the rice vegetation. The improvement of the nitrogen regime of the soil contributed to an increase in yield by 3.29 t/ha or 85% compared to the variant without nitrogen fertilization. It was also found that with fractional application and 150 kg/ha of nitrogen fertilizer, the maximum economic profitability of 78.1% was achieved. The obtained data, which indicates the benefits of fractional application and increased doses of nitrogen fertilizers, can be used to optimize agricultural technology by refining fertilization schedules and dosages. This will aid in achieving the maximum possible and economically viable yield of rice of the Syr Suluy cultivar, ultimately improving farming practices in the Kyzylorda region of the Republic of Kazakhstan.

The relevance of this study is determined by the need to optimize the production process of agrocenoses of spring rapeseed and establish the regularities of the dynamics of macroelements in the soil under the influence of different rates of mineral fertilisers. In this regard, the purpose of this paper was to cover the regularities of changes in the content of macroelements in typical low-humus chernozems at different stages of spring rapeseed culture development in the conditions of the Right Bank Forest Steppe of Ukraine. Field, laboratory, analytical, and statistical research methods were used in the study. It was established that the highest content of macroelements in the soil at all levels of mineral fertiliser is in the phase of leaf rosette formation by spring rapeseed plants (BBCH 15-18). As plants grow through the phases, it decreases and reaches minimum values in the ripening phase (BBCH 85-88). The highest content of nitrogen mineral compounds was noted in BBCH 15-18: 52.0-60.2 mg/kg of soil depending on the fertiliser variant, the content in the variant without fertiliser application – 49.8 mg/kg of soil. It was found that the maximum content of mobile phosphorus compounds in the soil was recorded in the first half of the growing season. It was found that the content of mobile potassium in the soil is dictated by the amount of applied mineral fertilisers. The highest content was noted at the beginning of the vegetation of spring rapeseed, with a gradual decrease until the seed ripening phase (BBCH 85-88). A close correlation was established between the accumulation of dry matter in the BBCH 55-58 period and the yield level (r=0.91). The materials of this paper are of practical value for the improvement of processes related to the development of the productivity of spring rapeseed crops in the conditions of the Forest Steppe of Ukraine, as well as the rational use of mineral fertilisers on typical low-humus chernozems
