“…The ZT also performed better regarding 1000 grains weight (g), probably due to more accumulation of resources as reported by Ali et al (2011). On the other hand, increasing doses of N increased 1000 grains weight (g), probably due to more vigorous growth at the higher dose of N as communicated by Shehab-Eldeen et al (2021).…”

We can overcome this global challenge by minimizing input costs and optimizing yields by employing appropriate tillage techniques and balanced fertilizer application. Appropriate tillage practices together with balanced fertilizer may be a promising practice of soil management to improve soil properties and crop production. The present study was carried out in wheat-maize cropping pattern (in the year 2019-20) at agricultural research farm of Gomal University, Dera Ismail Khan, Pakistan. The experiment was set up in a split-plot layout with a randomized complete blocks design. The nitrogen levels of 0, 90, 120, 150, and 180 kg N ha-1 were assigned to subplots. Tillage and nitrogen treatments separately had a significant impact on growth and yield characteristics, but the interaction between them had minimal effect, according to the findings. The tallest heights were found in the conventional tillage plots and the high N input (N180) plots, with heights of 101 and 104 cm, respectively. The spikes per m2 were found 242 in zero tillage plots, while the highest number of spikes per plot (265) was recorded in N180. The yield contributing factor number of grain spike-1 was 48.7 in zero tillage, while the nitrogen fertilizer @ 180 kg ha-1 yielded 52, 1000-grain weight of 35g was measured in conventional tillage and 38.8g in nitrogen fertilizer plots. Deep tillage where the nitrogen @ 150 kg ha-1 was applied gave the maximum grain yields, with 3113 kg ha-1 and 3415 kg ha-1, respectively. The benefit-cost ratio of different treatments was highest in zero tillage plots, with nitrogen @ 150 kg ha-1, at 1.65. Hence, it may be concluded from the study that both tillage and nitrogen levels influenced the agronomic properties of wheat, influenced the economics of farmers, and soil fertility.

Purpose. To study of yield formation and protein content in the grain of different ripening varieties of soft winter wheat under the condition of using various types and doses of fertilizers. Methods. Field and laboratory (determination of protein content), calculation (collection of protein), mathematical and statistical. Results. It was found that different fertilization systems reliably increased the grain yield of soft winter wheat. The use of N75 increased this indicator by 1.2 times and N150 by 1.4 times in the varieties studied, compared with the no-fertilizer variant. Yield with incomplete return of phosphorus-potassium fertilizer was only 2–3% lower than with complete mineral fertilizer. With the nitrogen-phosphorus and nitrogen-potassium fertilization systems, the yield was 5–7% higher than with the nitrogen system. At the same time, this indicator was 6% lower than in the full mineral fertilizer version of the trial. The use of 75 kg/ha nitrogen fertilizer per year increased the protein content to 13.5%, or by 10% compared to the control. In the double dose nitrogen fertilizer variant, the protein content increased to 14.2% or by 15%. The use of nitrogen fertilizers with phosphorus-potassium only contributed 2–4% to the increase of this indicator. Cultivation of winter wheat under the condition of application of N75 increased the collection of protein up to 724 kg/ha or by 33%, and with a double dose of nitrogen fertilizer – up to 848 kg/ha or by 55% compared to the option without fertilizer. In the N75P30K40 variant, protein yield increased by 10% compared to the nitrogen system. The application of a complete mineral fertilizer (N150P60K40) increased this indicator by 12%. Conclusions. It was found that the use of N75P30K40 increased the grain yield of soft winter wheat by up to 5.9 t/ha, or 7%, compared to the option where only 75 kg/ha of nitrogen fertilizer was applied. Yield development in soft winter wheat varies considerably from variety to variety. For example, this indicator was 35% higher in the ‘KWS Emil’ variety than in the ‘Prino’ line. In addition, the grain yield of both varieties is reliably influenced by the weather conditions during the growing season. The protein content of soft winter wheat varies considerably depending on the variety and the weather conditions. When growing soft winter wheat varieties, the protein content can vary by 12.8–15.1%. Weather conditions during the growing season can change this indicator by 13.1–14.7%. The protein content index in the grain of the ‘Prino’ line is significantly higher than that of the ‘KWS Emil’ variety. According to the protein yield per hectare indicator, the ‘KWS Emil’ variety (896 kg/ha) has a significant advantage over the ‘Prino’ line (774 kg/ha).

Purpose. To study the development of the yield structure of soft winter wheat varieties of different maturity under different types and doses of fertilizer. Methods. Studies on the development of the yield structure of soft winter wheat as a function of variety and fertilizer were carried out at the Uman National University of Horticulture in 2020–2022. Results. The soft winter wheat variety ‘KWS Emil’ formed the maximum number of stems in the phase of in all years of research – 693–948 pcs/m2 depending on the experimental variant. The phase of BBCH 50 in 2020 was characterized by a decrease in the number of stems to 533–639 pcs/m2 (or 1.5–1.6 times compared to BBCH 30), BBCH 93 – by an increase from 513 (in the control variant, without fertilizer) to 584–616 pcs/m2 (with the introduction of 75–150 kg/ha of nitrogen fertilizer per year). In the control variant, the average (for three years of research) weight of grains per ear of the variety ‘KWS Emil’ was 1.29 g. With the application of 75 kg/ha of nitrogen fertilizer, it increased to 1.39 g; N75P30K40 – to 1.47 g, or 14% compared to the control; double dose of complete mineral fertilizer – to the level of the variant with N75P30K40; N150 – to 1.37 g, or 6% compared to the control. The grain weight per ear of soft winter wheat ‘Prino’ varied on average during the research from 1.62 to 1.83 g and was significantly higher than that of the variety ‘KWS Emil’. Conclusions. The number of productive stems is highly dependent on the nitrogen content of the fertilizer. Thus, if in the control variety of ‘KWS Emil’ there were 420–513 stems/m2, the introduction of N150P60K80 increased the number to 562–624 stems/m2. The number of productive stems of the ‘Prino’ line varied from 209–432 to 277–613 pcs/m2. This line was also characterised by a higher weight and number of grains per ear than ‘KWS Emil’. The use of nitrogen fertilizer systems for plants of ‘KWS Emil’ variety contributed to the formation of grain weight in one ear at the level of 1.37–1.39 g with the number of grains 35.7–36.1 pcs.
