    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%.

    Impact of organic cultivation technology of fiber hemp (Cannabis Sativa L.) on soil agrochemical and bioecological properties
    (2023) Pylypchenko, A. V.; Marenych, M. M.; Hanhur, V. V.; Semenov, A. O.; Korotkova, I. V.; Rozhkov, A. O.; Karpuk, L. M.; Laslo, O. O.; Marinich, L. H.; Ponomarenko, S.; Пилипченко, Андрій Васильович; Маренич, Микола Миколайович; Гангур, Володимир Васильович; Семенов, Анатолій Олексійович; Короткова, Ірина Валентинівна; Рожков, А.

    Research into the correlations among components of soil biota is of significant importance for effective management of agroecosystems in organic agricultural production. Organic cultivation technologies contribute to increased nitrogen and phosphorus content in the soil, while reducing levels of P2O5 and K2O compared to inorganic methods. The influence of organic residue decomposers on macroelement composition in the soil has been examined, revealing a minimal impact on their levels. Organic technologies promote an augmentation of microorganisms, although there is a potential risk of heightened disease pathogens. It has been observed that under organic cultivation conditions, there is more intense tissue degradation, potentially attributed to higher microorganism activity. Transitional cultivation methods yield lower rates of degradation in comparison to organic techniques. The impact of organic technologies on the quantity of earthworms, nematodes, and springtails in the soil has been investigated. Organic practices have shown to increase their population, creating a favorable environment for soil biological indicators. Particular attention is given to correlation relationships between microorganisms responsible for nitrogen and phosphorus accumulation and the fungal component. High correlation values (r = 0.72–0.89) underscore the significance of comprehending these associations when employing organic cultivation methods. The study of correlations among soil biota components in organic production presents a promising task for the effective utilization of resources and the assurance of sustainable agroecosystem development.

    Weed Control and Winter Wheat Crop Yield With the Application of Herbicides, Nitrogen Fertilizers, and Their Mixtures With Humic Growth Regulators
    (2021) Korotkova, I. V.; Marenych, M. M.; Hanhur, V. V.; Laslo, O. O.; Chetveryk, O. O.; Liashenko, V. V.; Короткова, Ірина Валентинівна; Маренич, Микола Миколайович; Гангур, Володимир Васильович; Ласло, Оксана Олександрівна; Четверик, Оксана Олександрівна; Ляшенко, Віктор Васильович
    The aim of the present study was to determine the efficacy of the application of mixtures containing various combinations of humic substances, with herbicides and nitrogen fertilizers, in weed control and optimizing the plant nutrition system. We also aimed to evaluate the infuence of these substances on winter wheat productivity. Five Ukrainian winter wheat cultivars (‘Kryzhynka,’ ‘Smuhlyanka,’ ‘Slavna,’ ‘Kubus,’ and ‘Mulan’) were sown in a randomized complete block design, with three replications, in the years 2014 2019. The analysis of the effect of the compositions containing herbicides, with various physiologically active substances, in a mixture with humic preparations (Humifeld, 4R Foliar concentrate) was performed by counting weeds per square meter in each experimental plot. e best performance in weed control, including perennial species, was obtained from using a mixture of Grodil Maxi herbicide with the humic preparation, Humifeld. THe crop treatment of this mixture resulted in a 23.6% reduction in weeds, compared to the treatment with the Grodil Maxi herbicide only. At the same time, the complex application of a number of herbicides in a mixture with the humic preparation, 4R Foliar concentrate led to the opposite effect. Various applications of mixtures of humates (4R Foliar concentrate, 5R SoilBoost) with nitrogen fertilizers (ammonium nitrate; carbamide-ammonium mixture) to optimize the winter wheat nutritional system and yield increases have been studied. e highest yield increase of 20%–22% was harvested in the plots treated with 5R SoilBoost and 4R Foliar concentrate plus ammonium nitrate. In addition, the efficacy of wheat crop foliar feeding with mixtures of humates, plus a carbamide-ammonia mixture, in different phases of vegetation has been established. A yield increase of 10.0%–21.4% resulting from the use of such compositions was obtained.
