    Lack of water is one of the main abiotic factors that affect the change of plant production processes by imposing certain morphological, physiological and biochemical changes. The aim of the research conducted in 2019–2020 was to study the change in the productivity and yield of green beans of different cultivars of Vicia faba L. var. Major and the formation of a symbiotic system on surface drip irrigation. The results of the biometric analysis showed that the cultivation of faba beans under irrigation contributes to an increasing in plant height by 4.7–12.2%, the number of branches per plant increased by 17.3–30.0%, the leaf area of faba bean crops increased by 21.2–24.9%. The content of total chlorophyll increasing by 16.9–40.5%. Antioxidant enzymes activity decreased depending on the cultivar Catalase activity by 10.6–22.5%, Guaiacol peroxidase – 19.4–25.9%, Superoxide dismutase – 19.3–24.4%. The yield of green faba beans (Vicia faba L.) increased by 31.3–39.2%. Growing faba beans on irrigation helped to reduce the protein content by 1.4–2.1 %, but to reduce the dry matter content by 1.3–2.0%, which was significant in both indicators. In general, drip irrigation contributed to the improved development of bean-rhizobial symbiosis of faba bean plants. The mass of the nodules on the drip irrigation increased by 0.3 g plant–1 regardless of the cultivar, and their number is 1.5–9.0 pcs plant–1. The presented results give an idea of the functioning of the legume agrocenosis and the impact of irrigation on the main quality indicators of the product. Further research is to study the regimes (rates, timing, and multiplicity) of irrigation

    Theoretical Design of the Formation of Professional Communicative Competence of Future Non-Language Experts in the Process of Learning a Foreign Language
    (online, 2021-03-25) Lazariev, Oleh; Fernos, Yuliia; Komisarenko, Nataliia; Movchan, Liudmyla; Oliinyk, Olena
    Competence-based technologies used for teaching a foreign language in non-linguistic higher education institutions, put at the center of all education system student competence, providing comfortable, conflict-free conditions of its development, realization of natural and acquired potentials. The construction of a competence-based educational process presupposes the orientation of the training space on the competence sphere of students. The studied experience makes it possible to identify competencebased “platforms”, as well as the main “landmarks” for teaching a foreign language to future experts of non-linguistic specialties. Not only the general English language course, which is quite universal for all specialties, but also the professionally-oriented course, which depends on the chosen specialty in the higher education institution, acquires great importance in the training of future non-language experts. The competence orientation of teaching foreign languages to students of non-linguistic specialties is to ensure proficiency in a foreign language within the framework of both everyday communication and in the specialty at a creative and professional level. Theoretical design of the formation of professional communicative competence of future non-language professionals in the process of learning a foreign language confirms the feasibility of the proposed method, allows us to theoretically justify its effectiveness.
