    Fertilisation plays a crucial role in managing corn yields. Research conducted in 2021 − 2023 in the Central Forest-Steppe of ukraine under unstable moisture conditions demonstrated the positive impact of urea-ammonia mixture (uan) on the yield and sowing properties of maize maternal lines seeds across different maturity groups (P6/240, P5/320, P4/440). Applying 80 L/ha of UAN during the V10 (ВВСН 20) phase increased seed yield by 10.6 − 11.9% compared to the control. The highest seed yield was achieved with 120 L/ha of UAN, resulting in increases of 22.5% for P6/240, 21.3% for P5/320, and 16.4% for P4/440. however, increasing the uan dose to 160 l/ha led to a slight decrease in yield for lines P5/320 and P6/240. Statistical analysis confirmed that fertilisers significantly influenced seed yield, accounting for 37% of the yield variance, with the genetic characteristics of the maternal lines contributing 34%. The positive effect of liquid nitrogen fertilisers on the 1,000-seed weight varied from 3.4% to 21.8%, depending on lines genetics and fertiliser dose.

    Effectiveness of urea-ammonia mixtures for ertilisation of maize (zeamays l.) mother plants under conditions of unstable moisture
    (2024) Marenych, M. M.; Маренич, Микола Миколайович; Koba, K.; Hanhur, V. V.; Гангур, Володимир Васильович; Semenov, A. O.; Семенов, Анатолій Олексійович; Len, O.

    Studies in 2021-2023 under conditions of unstable moisture in the Central Forest-Steppe of Ukraine revealed a positive effect of urea-ammonia mixture (UAN) on the yield and sowing properties of seeds of maternal lines of maize hybrids of different maturity groups (P6/240, P5/320, P4/440). Based on the research results, it was found that the application of 80 l/ha of UAN in the V10 phase increased seed yield by 10.6-11.9% compared to the control. The highest level of seed yield of the maternal line of the early-ripening hybrid P6/240 (6.16 t/ha) by 22.5%, the mid ripening hybrid P5/320 (6.20 t/ha) by 21.3%, the late-ripening hybrid P4/440 (6.80 t/ha) by 16.4% and its maximum increase compared to the control was observed in the variant with the introduction of urea-ammonia mixture (UAN) at a dose of 120 l/ha. The subsequent increase in the dose of UAN to 160 l/ha was not effective, as the level of seed yield decreased in the hybrid P5/320 by 0.5%, P6/240 - by 3.9%. Statistical processing of the experimental data using the method of analysis of variance confirms the significant influence of fertilisers on the formation of seed yields of maize hybrids, which account for 37%. According to the experimental data, the positive effect of applying different doses of liquid nitrogen fertilisers on the weight of 1000 seeds, depending on the genetic characteristics of the hybrids and the dose of fertilisers, was noted to be 3.4-21.8%.

    Features of quality management of industrial hemp products (Cannabis sativa L.)
    (2026) Marenych, M. M.; Маренич, Микола Миколайович; Ovsianyk, O.; Semenov, A. O.; Семенов, Анатолій Олексійович; Hanhur, V. V.; Гангур, Володимир Васильович; Yurchenko, S.

    A brief review of current research on oil and protein content in industrial hemp seeds is presented. One of the main factors limiting the development of hemp production is identified as the long-term ban on cultivation, which slowed the improvement of agronomic technologies. The study aimed to assess the effects of fertilization, growth stimulants, sowing rate, and preceding crops on seed quality indicators of industrial hemp. Two experimental schemes were implemented. In the first scheme, factor A included mineral fertilization systems: Polyphoska 8:24:24:9S (165 kg/ha) + UAN-32 (300 kg/ha) and Ecoplant (200 kg/ha) + UAN-32 (300 kg/ha). Factor B involved seed and foliar treatments with growth stimulants, including Humifield, 1R Seed Treatment, Zinovii Grand, and their combinations. The second scheme evaluated the effects of preceding crop (winter wheat, maize, industrial hemp), seed sowing rate (1.0 and 2.0 million seeds/ha), and pre-sowing seed treatment with Zinovii Grand. All treatments were arranged in a randomized design. A stable positive correlation between the duration of the biological maturity period and oil content was established (r = 0.27–0.79), indicating that extending the vegetation period through optimized plant nutrition may effectively enhance oil accumulation. Regression models suggested that, within the studied Ukrainian agroclimatic context characterized by unstable moisture supply, certain management combinations may allow concurrent increases in straw and seed yield while maintaining—and in some cases modestly improving – oil and protein contents; however, extrapolation to other climatic zones requires additional validation. The application of Ecoplant combined with UAN-32 increased oil content by 0.6% compared with Polyphoska-based fertilization. Foliar application of Zinovii Grand and 1R Seed Treatment increased oil content by approximately 0.5%, particularly under less effective fertilization regimes. Oil content was primarily determined by pre-sowing seed treatment, which contributed more than 70% to its formation, while sowing rate had no significant effect. The influence of the preceding crop averaged 9% over three years, reaching 19% in individual seasons. Protein content was affected by a broader range of factors and their interactions. Pre-sowing seed treatment increased oil and protein contents relative to the untreated control; in several treatment combinations, oil content exceeded 30% and protein content exceeded 25%.
