“…In the soil and climatic conditions of the northern steppe of Ukraine, the yield increase of amaranth grain (Amaranthus paniculatus) from the application of complete mineral fertilizer (N 90 R 90 K 30 ) was low and formed only 0.42 t/ha, compared to control without fertilizers (Dudka, 2019). It is recommended to apply mineral fertilizers in the rate of N 120 P 70 K 70 (Bielski and Szwejkowska, 2015).…”

The research was conducted on the research field of Lviv National Agrarian University on dark gray podzolic light loamy soil. Hydrothermal conditions differed from the average of many years data by more precipitation. In 2019, during the growing season it fell by 53 mm above the rate, in 2020 -by 129 mm, in 2021 -by 73 mm. The aim of the research to define the amaranth nutrition system in conditions of sufficient and excessive moisture, seven rates of mineral fertilizer application were studied: N

“…Yield decreases both in sparse and dense plant placements on the field. Agrophytocenoses are known for their ability to self-regulate and are sensitive to excessive crop density, which leads to significant reduction of already formed morphological elements: premature drying and wilting of lower layers of leaves, decrease in stem and leaf mass, reproductive organs, and overall plant biomass, resulting in reduced grain yield (Dudka, 2019).…”

The main value of amaranth lies in its ability to accumulate a large amount of protein in its seeds and leaves. With a seed protein content of 15-18%, amaranth surpasses wheat (12-14%), rice (7-10%), maize (9-10%), and other grain crops. The purpose of this study was to establish the optimal seed sowing rates for amaranth under the conditions of the Western Ukrainian Forest-Steppe zone. The study employed general scientific methods such as analysis, synthesis, experimentation, description, observation, and comparison, as well as field methods like phenological observations and record-keeping, along with statistical and correlation-regression analyses for data processing. The sowing rates of the variety Kharkivskyi 1 were investigated under conditions of sufficient moisture on dark-grey forest soil. It was found that the field germination varied with different sowing rates. At a sowing rate of 0.2 million seeds/ha, the field uniformity was 70%, but it decreased to 60% at a sowing rate of 1.2 million seeds/ha, representing a 10% decrease. Higher sowing rates resulted in greater plant density. In the seedling stage, there were 14 plants per 0.2 million seeds/ha sowing rate, while at 1.2 million seeds/ha, the number of plants increased to 72/m². Plant survival during the vegetation period sharply decreased with increased planting density, from 86% at a sowing rate of 0.2 million seeds/ha to 45% at a sowing rate of 1.2 million seeds/ha. Therefore, before harvesting, the plant density was adjusted to 12-32 plants/m². The best combination of the main elements of the structure was found to be 21 plants/m² and 26 plants/m², with a grain weight per plant of 20.4g and 16.1g, respectively. The highest grain yield of amaranth variety Kharkivskyi 1 was obtained at sowing rates of 0.4 million seeds/ha and 0.6 million seeds/ha, resulting in 4.28 t/ha and 4.20 t/ha, respectively. Any increase or decrease in sowing rates led to a decrease in the yield level. The results of this study can be used for further establishment and improvement of the main elements of amaranth cultivation technology by both scientific institutions and agricultural farms

“…Cultivated plants, in particular amaranth, carry out nutrients in high quantities during the growing season with the accumulation of biomass and grain harvest. According to scientists [4], in order to obtain 10 centners of amaranth grain yield, plants must take out 20.6 kg of N, 13.2 kg of P2O5 and 5.6 kg of K2O from the soil. Amaranth green mass to take out even more nutrients.…”

From the agrochemical properties of soils, their nutritional regime is of great importance. Since, plant nutrition is associated with it. In serozem-meadow soils, the nitrogen regime is in the most vulnerable position. Since the content of ammonium and nitrate nitrogen in the soil is at a minimum. The introduction of nitrogen fertilizers improving the nitrogen regime of the soil has a positive effect on the growth, development and accumulation of amaranth grain yield. The most optimal fertilizer nitrogen rate was 250 kg / ha against the background of P150K200 (1-experiment), an increase in the nitrogen fertilizer rate to 300 kg / ha against this background did not significantly increase the yield of amaranth grain. The study of the norms of mineral fertilizers without applying manure and in combination with it showed that mineral fertilizers (NPK) and manure at a dose of 30 t / ha significantly improve the poor nutritional regime of serozem-meadow soils, creating a high level of nutrition for amaranth plants. At the same time, the highest level of the nutrient regime of the soil was observed with the combined application of mineral fertilizers with manure. The highest yield was obtained on the N200P140K100 +30 t / ha option.
