| Abstract | In the world, in terms of sown areas, barley inferior only to wheat, rice and corn, and in Ukraine – only to wheat and occupies 24.5 % in the structure of grain crops. At the same time, at the country's variety testing stations, the yield of barley exceeds 8.0–9.0 t/ha. However, with such a potential for productivity of modern varieties, its realization in production conditions is only 20–30 %. At the same time, research into the technology of growing spring wheat and barley using the No-till tillage system is currently relevant. Purpose of the work – to identify the patterns of the influence of fertilizer doses on the productivity indicators of spring grain crops under different tillage systems for the conditions of the central Forest-Steppe of Ukraine. The work is carried out in field experiments of crop rotation of Cherkasy DSGDS NSC "Institute of Agriculture of NAAS". Sowing was carried out in a five-field crop rotation. Structure of crop rotation: cereals – 60 % including: winter wheat – 20 %; spring eared – 40%; grain-legumes (peas) – 20 %; technical (soybeans) – 20 %. The predecessor of spring barley is spring wheat, spring wheat – soybeans. As a result of two-year research, the main patterns of the influence of tillage and fertilization on the productivity indicators of spring grain crops in the conditions of the central Forest-Steppe of Ukraine were established. The dependence on the decrease in the yield of spring grain crops (wheat and barley) was established: plowing, surface tillage, No-till after plowing, No-till after surface tillage. The formation of the highest yield level was facilitated by the use of plowing to a depth of 22–25 cm – 4.76 (spring wheat) and 4.11 t/ha (spring barley), or 0.23–1.15 and 0.12–0.55 t/ha, respectively, higher than other tillage options. The application of mineral fertilizers under all tillage options had a positive effect on the formation of the yield level – a significant increase in yield was at the level of 0.48–0.50 (spring wheat) and 0.42–0.54 t/ha (spring barley). At the same time, the most economically feasible was the application of mineral fertilizers at the rate of N45P45K45. On average, the share of the influence of the studied factors on the yield of the studied spring grain crops was: tillage (factor A) – 21–23 %, fertilization (factor B) – 16–18 %, and the interaction of factors – 58–61 %. | ||
