“…Szumiło and Rachoń [43] reported that delaying the sowing date primarily reduced the number of spikes per square meter. Sobko et al [44] demonstrated in their Jarecki and Czernicka [40] confirmed the usefulness of field measurements of plant parameters, such as SPAD and LAI, in assessing the effectiveness of fertilization of winter wheat and the response of plants to the applied fertilizers. The aforementioned authors observed that SPAD and LAI indices in winter wheat could serve as predictors for plant growth and grain yield.…”

“…Szumiło and Racho ń [43] reported that delaying the sowing date primarily reduced the number of spikes per square meter. Sobko et al [44] demonstrated in their study that different sowing dates did not affect the number of grains per spike but significantly modified TGW. The latter authors obtained the lowest TGW after sowing wheat on October 10 or 20.…”

“…Grain yields of wheat varied between the years of the study, ranging from 6.71 t ha −1 in 2021 to 7.45 t ha −1 in 2023 (Table 3). Shah et al [47] (2020) and Sobko et al [44] demonstrated that winter wheat yield decreased by one percent with each day of delay in the sowing date, and additionally, the plants had shortened developmental stages. Fu et al [16] reported in their study that delaying winter wheat sowing reduced yields from 6.14% to 13.72%; however, increased nitrogen fertilization alleviated this decline.…”

Common wheat is one of the most important cereal crops in the world. In cultivation, winter, spring, and facultative varieties of this species are known. In wheat agronomy, timely sowing and optimal nitrogen fertilization are particularly crucial practices, as both significantly impact yield and grain quality. In a three-year field experiment, the response of the winter wheat variety RGT Kilimanjaro to two sowing dates (recommended and delayed by 30 days) and varied nitrogen fertilization levels (100 kg ha−1, 150 kg ha−1, and 200 kg ha−1) was investigated. It was shown that the difference in grain yield between 2021 and 2023 amounted to 0.74 kg ha−1. The application of 200 N kg ha−1 significantly increased the Soil Plant Analysis Development (SPAD) index and Leaf Area Index (LAI) compared to the variant with a delayed sowing date and a nitrogen dose of 100 kg ha−1. Yield components (number of spikes per square meter, thousand grain weight) and grain yield were highest when wheat was sown at the recommended date and with the application of either 150 or 200 N kg ha−1. The number of grains per spike significantly varied between the variant with the recommended sowing date and a dose of 200 N kg ha−1 and the variant with a delayed sowing date and a dose of 100 N kg ha−1. The lowest grain yield was obtained at a 30-day late wheat sowing date when applying 100 N kg ha−1. The protein content in the grain was primarily influenced by nitrogen fertilization. Therefore, it can be concluded that delaying the sowing date of winter wheat by 30 days results in a decrease in grain yield but can be compensated by increased nitrogen fertilization. The most favorable economic effects were achieved with the application of 150 N kg ha−1 at the recommended sowing date. Considering that high doses of nitrogen fertilization can have adverse effects on the natural environment, research in this area should be continued.

“…The introduction of 90 kg ha -1 of phosphorus fertilizer at the beginning of flowering increased productivity and improved the quality of Onobrychis viciifolia herbage. Phosphorus supplementation improve the dry mass accumulation and the chemical compound of legumes [Comakli and Tas, 1996;Türk et al, 2007;Shalyuta and Kostitskaya, 2018;Sikora et al, 2020;Sobko et al, 2023] showed that fertilization with P increased the dry matter yield, the content of P, Ca, and Mg in the products, and the amino acid composition. The nutrient content is not necessarily the only criterion for assessing plant nutritional value [Thomson, 1982 Sainfoin responds well to the application of 60 kg ha -1 of nitrogen on frozen soil before the onset of vegetative growth, or they are mixed by cultivators to a depth of 10-12 cm.…”

The significance of this study stems from the imperative to justify and advance agrobiological foundations aimed at enhancing the cultivation practices of Onobrychis viciifolia. There exists a compelling necessity to refine agronomic methodologies and streamline their comprehensive efficacy within the technological phases of cultivation. This study is aim to provide a critical analysis of scientific problem of substantiation of biological and organic foundations of the technology of Onobrychis viciifolia growing. Innovative technological interventions were formulated by extrapolating discerned patterns of influence pertaining to climatic and meteorological factors. Patterns governing the growth, development, and productivity formation of Onobrychis viciifolia were identified, and both the theoretical and practical principles of contemporary methods for cultivating perennial legumes were established. The chemical compound of aboveground biomass of Onobrychis viciifolia is varied depending on researched factors. Fertilization practically did not increase the productivity of Onobrychis viciifolia. The natural fertility of low-humus chernozem soil ensures the formation of a high, stable yield without fertilizing. This is the evidence that Onobrychis viciifolia compares favorably with other perennial legumes. Due to its biological characteristics, it is much more effective, especially in leveraging natural factors for the yield formation, i.e., it plays a significant role in the biologization of plant production, and in obtaining the most environmentally friendly, high-quality, yet cheap feed. The outcomes derived from the conducted research indicate that, under uniform soil conditions and varying fertilizer levels, the mowing height emerges as the predominant factor. The highest concentrations of nutrients within the overground biomass of Onobrychis viciifolia were noted at a cutting altitude of 11 centimeters. Concurrently, an elevation in crude protein and ash content was observed, accompanied by a concomitant reduction in the index of crude fiber.
