“…makes up almost 5%. Durum wheat grain is the main raw material for the production of high-quality pasta and cereal products (Panayotova et al, 2021). The production of valuable grain products from wheat is possible due to the use of high-protein grain in their production technology (Osokina et al, 2020).…”

Durum wheat (Triticum durum Desf.) grain is the main raw material for the production of high-quality pasta and cereal products. The research was conducted at Uman National University of Horticulture (Ukraine) in a long-term stationary experiment, founded in 2011. The aim of the work was to study the impact of long-term use of various fertilization systems (with incomplete return of nitrogen, phosphorus and potash fertilizers) on the yield and quality of durum winter wheat grain. The long-term application of nitrogen, nitrogen-potassium, nitrogen-phosphorus and nitrogen-phosphorus-potassium systems in the field crop rotation has a strong impact on the formation of durum winter wheat yield. Long-term use of N150P60K80 increases it from 3.6 t ha-1 up to 4.9 t ha-1 (p≤0.05). The use of half a dose of complete mineral fertilizer provides 4.5 t ha-1 (p≤0.05). Variants with incomplete return of phosphoruspotassium fertilizers, as well as paired combinations with a nitrogen component, provide the formation of 4.6–4.8 t ha-1 grains. Nitrogen fertilization systems increase grain yield to 4.2–4.5 t ha-1 depending on the fertilizer dose. It should be noted that durum winter wheat responds well to the use of nitrogen fertilizers, as the protein content increases from 13.3 to 14.8–15.9 % (p≤0.05), and the gluten content from 28.0 to 31.1–33.4% (p≤0.05) depending on the fertilization system. The protein content was most affected by the application of nitrogen component from complete mineral fertilizer.

Abstract. The effectiveness of mineral fertilization on wheat productivity was determined in a field experiment on Alluvial-meadow soil (Fluvisol, FAO 2015) at the experimental field of Tsalapitsa village, Plovdiv region, during 2019-2020. Four increasing rates of nitrogen fertilization along with a constant background of phosphorus fertilization were tested in the following variants: N40P100; N80P100; N120P100; N160P100, and N0P0 (control) – without any fertilization. The influence of these variants on yield and the content of basic macro- and microelements in wheat’s dry biomass were assessed. Plant samples were collected at the full maturity phase of wheat, with each variant sampled in triplicate, to determine the concentrations of N, P, K, Ca, Mg, Cu, Zn, Mn, and Fe. Correlation analysis and analysis of variance (ANOVA) were employed to identify dependencies between observed variables. Significant differences between the variants for N% content in grain, chaff and straw of wheat were established. The highest nitrogen values were observed in the grain of the N160P100 and N120P100 variants, at 2.10% and 2.02%, respectively. The applied fertilization had a significant positive effect on the accumulation of potassium, calcium, copper, manganese and iron in wheat biomass. This finding was supported by the correlation coefficients between fertilizer rates and N (R = 0.948), Ca (R = 0.854), Cu (R = 0.681), Mn (R = 0.735), and Fe (R = 0.769) in the wheat grain. Significant yield differences were observed among the variants, with the highest yield recorded for N120P100 (7123.0 kg/ha), more than tripling that of the control variant. The uptake of nitrogen, phosphorus and potassium by the total biomass of wheat increased depending on the fertilization rates and it was the highest in the N120P100 variant.
