“…According to many scientists, the effective use of fertilizers can increase the resistance of grain sorghum to unfavorable external factors, increase germination energy, ensure the intensive growth at the early stages of organogenesis and a high productivity of generative organs [24][25][26].…”

In the process of gradual warming, producers carry out the search of the crops, which develop high productivity of excellent quality grain in the difficult soil-climatic conditions. Grain sorghum is one of these crops. Similar to any other agricultural crop, its productivity depends on the effect of numerous factors including the elements of the cultivation technology. One of these elements is the application of mineral fertilizers. The purpose of the research was to study the effect of the plant mineral nutrition on the formation of the structure indicators of grain sorghum yield capacity in the conditions of the Right bank Forest steppe zone of Ukraine. The experiment was carried out in the zone of unstable humidity in 2016–2020. The trial scheme consisted in studying grain sorghum cultivars and various fertilizer rates; the trial was initiated with the method of regular replications, a fourfold replication was applied. Having analyzed the research results, it was found out that as the fertilizer rates increased, the element indicators of the yield structure also increased; in turn grain yield capacity of the studied cultivars was higher. However, the optimal fertilizer rate for the expected yield is the estimated one which will reduce the production cost of the output.

The study of the elements of grain sorghum cultivation technology, in particular, the application of mineral fertilizers, is one of the main promising tasks, which will contribute to the formation of high crop productivity. The article shows the results of studies on the effect of various doses of mineral fertilizers on the the growing season duration, feld germination and biometric indicators of sorghum plants of grain varieties Dniprovsky 39 and Vinets in the Right-Bank Forest-Steppe of Ukraine. The studies were carried out in 2016–2020 in the conditions of the Bila Tserkva Experimental Breeding Station of the Institute of Bioenergy Crops and Sugar Beet of the National Academy of Sciences – the zone of the Right-Bank Forest-Steppe of Ukraine. It was found that the use of fertilizers at a dose of N30P30K30 and N60P60K60 increased the duration of the growing season of grain sorghum plants by 1–2 days compared to the control, and at a dose of N90P90K90 and N120P120K120 by 2–3. At the calculated dose of fertilizers, the growing season was the shortest and amounted to 114 days for the Dniprovsky variety 39 and 112 days for the Vinets variety. The greatest inﬂuence on the feld germination of seeds in the years of research was exerted by weather conditions – 27.1 % and fertilizers – 13.2 %, and the degree of inﬂuence of varieties was much less 9.5 %. The results of the correlation-regression analysis reveal a strong relationship between the stem diameter and plant height, as well as between the leaf surface area and plant height. It was found out that with the application of maximum doses of fertilizers (N90P90K90 and N120P120K120) and the estimated (N50P40K70) received the maximum growth and development of plants, so it is advisable to apply the estimated dose of fertilizers below the planned yield, which will reduce production costs. Key words: varieties, fertilizers, feld similarity, plant height, leaf area.
