The aim is to study how presowing usage of biologies Mycofriend, Mikovital and Florobacillin influences on biometric indicators of maize, its productivity and soil moisture holding capacity. Using mycorrhizal fungi and nitrogen-fixing bacteria, we have received positive results about their influence on plant growth and development and maize yield forming. Leaf surface area in variants with fungi Trichoderma harzianum Rifai (Mycofriend bio-based product), and Tuber melanosporum Vittad (Mikovital bio-based product) and bacteria Bacillus subtilis Cohn. (Florobacillin bio-based product) was counted on 30th, 60th, 90th and 120th days of vegetation and was estimated by 11.2–90.0% higher compared to the control. Leaf mass and root system mass exceeded control indicators by 24.0–48.9%, respectively. Plants height in these accounted periods was higher by 4.0–31.5% compared to the control. In addition, in these variants, soil moisture holding capacity increased by 7.3–38.1%, share of soil lumps smaller than 0.25 mm decreased by 2.8–7.2%. Grain yield of Maize in variants with mycorrhizal fungi and nitrogen-fixing bacteria was 1.64–2.68 t/ha higher than in the control. It should be noted that presowing usage of fungus Trichoderma harzianum Rifai on plants seeds, provides better efficiency on plants’ growth and development and their productivity.
To ensure the maximum protection of agricultural crops from climatic factors unfavorable for their growth and development, it is necessary to create an optimal number of field protection forest strips. In particular, for the Forest-Steppe zone of Ukraine, less than half of the optimal needs are available, which indicates an urgent need for their additional creation. The expediency of creating fast-growing and multifunctional field forest strips is substantiated, and the productivity of new bioenergy crops during their formation for use in beekeeping and as biofuel is determined. For this purpose, a model of the artificial formation of a forest strip with its possible further exploitation is proposed. The most optimal one is to develop the concept of creating field forest strips with the use of multifunctional tree species, which, in addition to the function of wind, water and dust retention, will also perform other economic tasks. In particular, along with their intended purpose, they can be used as raw materials for biofuel production and as early honey plants. For the accelerated creation of field protection forest strips, it is advisable to use mixed 6–8- row plantings, where the middle 2–3 rows are planted with the involvement of tree species, including the use of species valuable as raw materials for beekeeping. These forest strips are complemented on both sides by planted strips of energy crops, which are important for beekeeping and are a valuable resource for obtaining fuel raw materials. For this purpose, it is advisable to plant 10–12 thousand pieces on one hectare poplar cuttings (Populus sp.), 1250 pieces of paulownia plants (Paulownia tomentosa Steud.) with a row width of 2×4 m and 17–18 thousand pieces cuttings of energy willow (Salix viminalis L.). It is also possible to replace part of the poplar cuttings with cuttings of common robinia (Robinia pseudoacacia L.) and linden (Tilia cordata Mill.). The creation of such plantations near settlements will contribute to their significant use of raw materials and will be quite effective in carrying out their main function of ecological stabilization of agro-landscapes.
