Item Effect of grain meteorological factors and time of spring vegetation recovery on the development and yield of winter grain crops in Ukraine.(2014) Калініченко, Антоніна Володимирівна; Гангур, Володимир Васильович; Маренич, Микола Миколайович; Kalinichenko, A. V.; Hanhur, V. V.; Marenych, M. M.Item Features of forming the productivity of modern hemp varieties using organic cultivation technology(2023) Pylypchenko, A. V.; Marenych, M. M.; Hanhur, V. V.; Пилипченко, Андрій Васильович; Маренич, Микола Миколайович; Гангур, Володимир ВасильовичSeed hemp can be used to produce products and restore soil fertility. The adaptive potential of cannabis varieties can be implemented by optimising their cultivation technologies. The purpose of this study was to substantiate the features of forming the productivity of cannabis varieties adapted to organic cultivation technologies. Field studies were conducted during 2019-2021 on leached chernozems. Research methods: field, laboratory, statistical and comparative calculation. The regularities of yield formation of hemp straws, fibre, and seeds depending on the genetic potential of varieties and cultivation technology were investigated. The suitability of five hemp varieties for organic cultivation was evaluated. It was established that the introduction of organic cultivation technology has a positive effect on crop productivity. With organic cultivation of Hliana and Hloba varieties, the increase in the yield of straw (0.07-0.11 t/ha) was statistically insignificant compared to inorganic technology. Cultivation of Zolotoniski 15 and Sula varieties using organic technologies increased the yield of hemp straw by 0.14 t/ha. The Lara variety showed an insignificant decrease in the straw yield. This confirmed the theory that the introduction of organic cultivation of hemp will not lead to a decrease in yields. Organic technologies for growing hemp contributed to an increase in their yield compared to the traditional one, provided that varieties were selected correctly. The best suitability for organic cultivation in terms of fibre yield was recorded in the Lara variety. The obtained results will be used to improve and introduce organic technologies for growing adapted hemp varieties, depending on the purpose of fibre or seeds.Item Formation of the Quality Indicators of Hemp (Cannabis sativa L.) Seeds Sown under Organic Growing Technology(2023) Pylypchenko, A. V.; Marenych, M. M.; Hanhur, V. V.; Semenov, A. O.; Sakhno, T. V.; Пилипченко, Андрій Васильович; Маренич, Микола Миколайович; Гангур, Володимир Васильович; Семенов, Анатолій Олексійович; Сахно, Тамара ВікторівнаThe oil content of hemp seeds is controlled by the genotype and in the conducted studies did not depend on the growing technology; however, this factor had a synergistic effect with others. The protein content of hemp seeds during the years of research did not depend on weather conditions. Like other quality indicators, it had a slight variation, which indicates the significant role of the genetic characteristics of the varieties. On average, over the years of research, the protein content of the variants grown according to conventional technology was 25.2%, and according to transitional technology, it was 0.03% higher, which was within the limits of statistical error. The organic technology ensured the protein content at the level of 25.3%, and the use of the BioStymix-Niva microbial biodegrader - biodestructor contributed to the further growth of the indicator to 25.4%. The oil content of hemp seeds is not limited by other important characteristics, such as the yield of the hemp stems or the fiber content. Only the Glyana variety showed inverse correlations with plant height, hemp stems and seed productivity, they were of medium strength (r = -0.60 – -0.43). In the Zolotoniski 15 variety, only one inverse relationship was recorded, i.e. plant height (r = -0.57). No correlation was established between protein content and oil content in seeds. Correlations may change depending on other factors of cultivation, including weather conditions, elements of technology, etc., but the evaluation of varieties for cultivation according to these characteristics can significantly increase the efficiency of the production of cannabis products.Item 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.; Laslo, O. O.; Marinich, L. H.; Пилипченко, Андрій Васильович; Маренич, Микола Миколайович; Гангур, Володимир Васильович; Семенов, Анатолій Олексійович; Короткова, Ірина Валентинівна; Ласло, Оксана Олександрівна; Марініч, Любов ГригорівнаResearch 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.Item The efficiency of humic growth stimulators in pre-sowing seed treatment and foliar additional fertilizing of sown areas of grain and industrial crops(2019-06-18) Marenych, M. M. ; Hanhur, V. V.; Len, O. I.; Zhornyk, I. I.; Kalinichenko, A. V.; Маренич, Микола Миколайович; Гангур, Володимир Васильович; Лень, Олександр Іванович; Жорник, Ірина Іванівна; Калініченко, Антоніна ВолодимирівнаThe aim of the research was to establish the effectiveness of preparations, made on the basis of humic and fulvic acids on the yields of crops in case of different methods and amounts used. The experiments were held with varieties and hybrids of winter wheat, soya, corn, and sunflower. Based on the obtained results of investigation during the period of 2015–2017, the positive impact of foliar additional fertilizing with 4R Foliar Concentrate growth stimulator on the basis of humic and fulvic acids on the formation of productivity of the main crops sown areas was established. Proceeding from the results of the research, the using of growth stimulators based on humic and fulvic acids, which contain high concentrations of these substances, can be recommended as an expedient and efficient measure of raising the productivity and improving qualitative indicators of corn, sunflower, soya, and winter wheat yields.Item Weed Control and Winter Wheat Crop Yield With the Application of Herbicides, Nitrogen Fertilizers, and Their Mixtures With Humic Growth Regulators(2021) Korotkova, I.
