The results of the research of the impact of the introduction of biologicals Biocomplex-BTU and Organic-balance on seed productivity and yield properties of winter rye varieties Siverske and Intensive 99 were presented in the article. The aim of the research was to determine the impact of biologicals on seed productivity, sowing qualities and yield properties of winter rye seeds in the conditions of the Forest-Steppe of Ukraine. According to the results of the research, the combination of pre-sowing seed treatment and double spraying of crops: in the phases of spring tillering (III e.o.) and plant emergence in the tube (IV e.o.) increases seed productivity by 3.1–11.5%. It is determined that pre-sowing seed treatment provides an increase in sowing qualities of seeds (germination energy, laboratory germination) by an average of 2.8-3.8 %. It is recommended in the Forest-Steppe conditions for farms growing basic (elite) seeds of winter rye to use biological products Biocomplex-BTU or Organic-Balance in a complex way, namely: pre-sowing seed treatment (2.0 and 1.5 l / t) and double spraying of crops in the phases of spring tillering (0.8 and 0.5 l / ha) and the release of plants into the tube (0.8 and 0.5 l / ha, respectively). This provides an increase in grain and seeds in winter rye varieties by an average of 0.42 and 0.36 t / ha, depending on the biological product.

Goal. To determine the technical efficiency of the novel fungicides against root rot of pumpkins in the area of ​​the Right Bank Forest-Steppe of Ukraine. Methods. The experiments were conducted in 2016—2018 in the Right-Bank Forest-Steppe of Ukraine (Khmelnytsky region) on the following varieties: common pumpkins — Ukrainskyi bahatoplidnyi, hull-less pumpkins — Shtyriiskyi. Assessment of severity, spread of root rot, technical and farm efficiency was carried out according to generally accepted methods. To control the development of the disease, the following preparations were investigated: Maxim 480 FS, FS, Inshur perform, TK, Phytocide, s., Trichoderma blend Bio-Green Microzyme TR, EC. Results. During the study period, root rot was observed on pumpkins of both studied varieties annually. In the laboratory, it was found that the causative agents of root rot on pumpkins were fungi of the genus Fusarium Link. The development of the disease in control ranged from 11.2 to 17.6%. When biological preparations were used on the variety Ukrainskyi bahatoplidnyi, technical efficiency was at the level of 52.6—62.8%, on the variety Shtyriiskyi — 43.4—59.2%. The best effect against fusarium root rot was recorded for seed treatment with Trichoderma blend Bio-Green Microzyme TR. Pre-sowing treatment of seeds with Inshur Perform and Maxim 480 FS reduced the development of the disease by 3.6—4 times. On both varieties, biological products showed lower technical efficiency compared to chemical preparations. The use of pesticides made it possible to obtain a yield of pumpkin seeds with the use of biological products at the level of 0,431—0,435 t/ha on the variety Ukrainskyi bahatoplidnyi and 0,308—0,315 t/ha — on the variety Shtyriiskyi. When seeds were treated with chemical pesticides, the yield was 0,456—0,465 t/ha and 0,319—0,325 t/ha, respectively. That is, pre-sowing seed treatment allows to save from 4.1 to 12.9% of crop yield. Conclusions. Under conditions of the Right-Bank Forest-Steppe of Ukraine pumpkin plants are annually affected by fusarium root rot. The use of pesticides allows to save the seed yield in the range from 0.012 to 0.053 t/ha. The best technical efficiency was observed on the variants with the disinfectant Maxim 480 FS, TH with a consumption rate of 1.0 l/t and the biological product Trichoderma blend Bio-Green Microzyme TR, EC with a consumption rate of 50 ml/t.

The Impact

The study of the dynamics of plant growth and yield of vegetable crops (carrot variety Absheron winter (Daucus carota subsp. sativus (Hoffm.) Schьbl.) and radish variety Virovsky white (Raphanus sativus var.radicula Pers.)) was conducted in the field conditions after presowing exposure to different temperatures: I option – sowing of seeds exposed to low temperatures (for 15 days the swollen for 24 hours seeds were kept at a temperature of 0±1°С); Option II - sowing of seeds exposed to variable temperatures (for 5 days, the swollen for 24 hours seeds were exposed to variable temperatures of + 20°C (8 hours) and 0±1°C (16 hours) and then 10 days at a temperature of 0±1°C; K1 – sowing dry seeds; K2 – sowing soaked seeds. The impact on the seeds of low and variable temperatures caused an increase in growth processes, both in radish and carrot. Both studied crops showed a tendency to increase the yield to a greater extent when exposed to swollen seeds with variable temperatures. Thus, the average weight of radish crops exceeded the control variant by 47.1% and carrots by 27.6%. The yield of root crops per m2increased by 36.4% for radish and 30.0% for carrot. To increase the productivity of vegetable crops, we recommend using the studied methods of pre-sowing seed treatment in practice.

The results of assessing the effect of biological preparations and a seed disinfectant on the technological qualities of grain of soft spring wheat Novosibirskaya 31 are presented. The effectiveness of the use of biological plant protection products was studied in the field experiment, laid down in 2020 in the forest-steppe conditions of the Ob region. Pre-sowing seed treatment included the following options: control (without treatment); Trichodermin, P (Trichoderma viride, titer more than 6 billion spores/g), consumption rate – 15 kg/t seed; Sporobacterin, SP (Bacillus subtilis + Trichoderma viride, strain 4097), consumption rate – 0.5 kg/ton of seeds; Scarlet, ME, chemical standard (imazalil (100 g/l) + tebuconazole (60 g/l), consumption rate – 0.3 l/t of seeds. The use of the preparations contributed to an increase in yield by 0.40 and 0.52 t/ha when using Trichodermin and Sporobacterin, respectively, and by 0.08 t/ha when using fungicide Scarlet. In this case, the mass of 1000 grains increased by 0.84, 0.80 and 0.96 g, respectively, relative to the control. The preparations Trichodermin and Sporobacterin had a significant effect on the growth of grain in length and width relative to the control – by 5.4-6.9 and 9.6%, Scarlet – by 10.6 and 13.9%, respectively. Pre-sowing seed treatment contributed to the growth of such indicators of the caryopsis as volume (by 19.6–29.3%), surface area (by 12.1–19.2%), and sphericity (by 6.3–7.8%). To a greater extent, they increased with the use of fungicide Scarlet. Getting larger grain led to an increase in the endosperm content by 0.76–1.14%. A close correlation has been shown between the indicators of the mass of 1000 grains and the linear grain sizes (r = 0.92–0.98), as well as with the grain volume, sphericity and endosperm content (r = 0.98–0.99). Pre-sowing treatment of spring wheat seeds provides grain with improved technological properties.

The Impact

The mycoflora of winter wheat seed consists of various fungi that differ as to the parasitism rate. Their harmfulness is connected with their phytotoxic action and ability to produce mycotoxins. Assuming that essential oils have an effective antifungal impact, we studied the effectiveness of 13 essential oils which were produced by LLC "Aromatyka", Ukraine (cinnamon, orange, peppermint, rosemary, vervain, ylang-ylang, sandal, fennel, lavender, eucalypt, bergamot, frankincense, and geranium) on securing of a group of fungi from winter wheat seeds. The seed mycoflora of Bogdana variety harvested in 2017-2020, which was grown in the North- Eastern Forest-Steppe zone of Ukraine (Sumy oblast), was analyzed. A fungi complex analysis was made on the media PGA. The impact of essential oils on seed germinating ability and the length of wheat sprouts on the 7th day has been determined. A longterm studying of seed treatment by essential oils showed their effects on mycoflora formation. These plants affected not only the fungi amount but also changed their secure spectrum. The studies admit a negative impact of fungi on seed germination and plant development. The highest seed germination equaled 95% under its treatment with rosemary and orange oils. However, under seed treatment with rosemary oil, there appeared Fusarium sp. and Bipolaris sorokiniana (Sacc.) Shoem., which harms seed germination. Orange oil has increased the number of fungi of Penicillium sp. The best results (based on three indices) had sandal oil, under which the fungus colony has increased half, and seed germination equaled 61%, the sprout length was maximal when applying other oils (58.8 mm). The essential oils which fully inhibited seed and fungi development (cinnamon, fennel, vervain, geranium) were determined. The study of two of them as fungicides for treatments at the beginning of wheat flowering proved a similar effect to falcon on the change of the internal seed mycoflora.

The purpose of the research was to study the effect of mineral fertilizers and biological product Bisolbi-fit as a modifier on the oat productivity. The studies were carried out on the experimental field of Ulyanovsk Research Institute of Agriculture, branch of Sam SC RAS. The soil was leached, heavy-clayey chernozem. The experiment was carried out in a 3-fold repetition by the method of split plots with a systematic arrangement of options. The total area of one plot was 145 m2 (5.8×25), the accounting area was 100 m2 (4×25). The experiment scheme was as follows: 1. Control; 2. Presowing seed treatment with BisolbiFit in a dose of 400–600 g/t; 3. N15P15K15 in a dose of 15 kg ai/ha; 4. N15P15K15m in a dose of 15 kg ai/ha; 5.½ N15P15K15m in a dose of 7.5 kg a.i./ha. The effectiveness of the fertilizers was assessed during the cultivation of crops for three backgrounds: 1) zero – without fertilization; 2) NH4NO3m – treated with BisolbiFit in the dose of 40 kg a.i./ha; 3) NH4NO3 – in a dose of 40 kg ai/ha. It was established that the use of the microbiological preparation based on the Bacillus subtilis strain Ch-13, intended both for inoculation of seeds and use as a biomodifier of mineral fertilizers, had a positive effect on the crop structure, yield and grain quality. The most effective option was the one with Azofoska applied in a dose of 15 kg and modified with BisolbiFit at the rate of 4 kg per one ton of fertilizers on all the backgrounds. The use of BisolbiFit both for the pre-sowing seed treatment and treatment of mineral granules, increased the NPK payback by the yield gain.

The Impact

Possibility of pre-sowing seed treatment with growth regulators of steroid and iridoid nature has been studied while growing onions. In the experiment, an "ecostim" preparation has been used for the pre-sowing treatment of onion seeds, the active ingredient of which is the glycoside of the steroid nature of tomatosides isolated from the seeds of Solanum lycopersicum L., as well as the sum of iridoid glycosides (linarosides) from Linaria vulgaris Mill. To identify the technological parameters of the use of plant growth bio-regulators preliminary testing has been conducted in the Laboratory of Natural Bio-Regulators of the Institute of Genetics, Physiology and Plant Protection, A comparison of the effectiveness of the compounds obtained on the germination of onion seeds has shown that the greatest stimulation has been achieved by using low concentrations (0.0001% - 0.001%) of tomatoside solutions (eostimis preparation) and higher concentrations (0.005% - 0.01%0 of linarosides. Production tests have been carried out in the field in the Pridnestrovian Research Institute of Agriculture. Variety specificity of the impact of natural bio-regulators has been determined by the example of 3 varieties of onions, different in terms of maturation, resistance, etc. (Pinguin, Diamant and Chalcedon). It has been proved that the effect of the tested growth regulators has a pronounced varietal specificity and mainly is determined by the early maturity of the variety. It has been found that the compounds studied were most effective when growing onions under unfavorable conditions, and the amount of iridoid glycosides from the linaria had a greater stimulating effect compared with the tomatoside. Seed treatment with bio-regulators has provided the simultaneous emergence of seedlings, the leveling in growth and development of plants, as well as increased the yield of onions by 27.6% - 41.3%.
