Ecologically sustainable and economically feasible crop cultivation technologies, including application of biologically active substances, are required for formation of a consistently high and excellent soybean yield. These substances, when used in minimal doses for pre-sowing treatment of seeds and vegetative plants, provide high field germination and plant resistance to unfavorable environmental factors, promote an increase in productivity by ensuring accelerated germination of seeds, their increased germination capacity and resistance to unfavorable agro-climatic conditions of the growing season. The aim of the research was to determine the degree of influence of various combinations of biological products and treatment methods on growth processes and productivity of soybean of the northern ecotype. The influence of various types of pre-sowing seed treatment on germination energy, germination capacity and morphometric parameters of soybean shoots was studied. The biological product “Floravit” was used in the experiments in combination with rhizotorphin, seeds were treated before sowing; the germination energy, laboratory and field germination capacity were found. Also, additional treatment of vegetating plants was carried out with the biological product “Floravit”. Observations of the symbiotic activity of plants were carried out, the productivity of plants was recorded at the end of the growing season. It was found that soaking of soybean seeds in water solution of “Floravit” (concentration - 1.4 · 10-4 g / ml; consumption - 1 l / kg) with subsequent treatment with rhizorphin (consumption - 3–5 g / kg) has a growth-stimulating effect at the initial stages of plant development, promotes fast and friendly shoots. Afterwards, the plants form a more powerful symbiotic apparatus and higher productivity. The obtained results - an increase in germination energy, laboratory and field germination capacity, symbiotic activity of plants and parametres of crop yield structure indicate a fairly high efficiency of “Floravit” application.

There have been presented the study results on the effect of pre-sowing seed ozonation of narrowleaf lupin (Lupinus angustifolius) and common oat on their germination energy, germination capacity, productivity and product quality. The study was carried out in the period from 2018 to 2020 in laboratory and field conditions of the Kostroma RIA, the branch of the FSBSI “Russian Potato Research Center named after A.G. Lorkh”. The purpose of the current study was to find out the efficiency of pre-sowing seed treatment with an ozone-air flow and treatment with a biological product for their germination energy, germination capacity, productivity and product quality. The objects of the study were the common oats variety ‘Yakov’ and the narrowleaf lupin variety ‘Belozerny 110’. The seeds of the lupin-oat mixture were ozonized at a dose of 5.0 mg/m3 for 15 minutes and 30 minutes using an RIOS-10(20)-0.5 ozonizer. For comparison, the seeds were treated with the biological product ‘Fitosporin-M’. Ultimately, there were identified the best parameters of the pre-sowing seed treatment of the lupin-oat mixture. On average, over the years of study, pre-sowing seed ozonation greatly improves the germination energy of agricultural crops on 4.8–8.3%, laboratory germination was improved on 3.0–5.0%. The largest green mass productivity of lupin-oat mixture during pre-sowing seed treatment for three years was 26.1 t/ha in the variant with an ozone dose of 5.0 mg/m3 for 15 minutes, which was more than control on 29.2%. In the variant with ozonation time increase to 30 minutes, the average productivity was 23.2 t/ha, which was 14.8% more than in the control. Pre-sowing seed ozonation contributed to dry matter increase on 14.2–19.0%; crude protein yield increased on 32.8–53.2%; crude protein percentage in grain increased on 14.1–16.8%; metabolizable energy increased on 3.7–5,1%; fodder units increased on 4.3–6.5% compared to control. When treating seeds with a biological product ‘Fitosporin-M’, the average productivity was 22.8 t/ha, which was on 12.9% more than control, an increase in dry matter was on 16.6%, an increase in crude protein yield was on 19.6%, an increase in crude protein percentage in grain was on 0.8%, an increase in metabolizable energy was on 1.9%, an increase in fodder units was on 1.0%.

Abstract The production experiments were carried out based on the farm “Yaroslav the Wise” of the Starooskol district of the Belgorod region. The article studies the effect of the biological product Biogor KM during the pre-sowing treatment of grain in combination with double spraying of growing plants of spring durum wheat Dar Chernozemya 2. One of the experiments provides for grain processing with the period of “germination-ripening” of its wheat plants reduced by 8 days. The second variant, in addition to processing the grain, had two sprayings carried out during the growing season. The second experiment lasted even less by 12 days in comparison with the control variant. The article establishes the positive influence of the biological product on the formation of the productivity structure of spring durum wheat plants. Grain processing in combination with spraying during the growing season led to the formation of the best productivity structure: plant height was 39% higher, the number of spikelets was 41.8% higher, the number of spikelets was higher by 35.3%, and the grain weight per spike was 39.2%. versus the control variant. The yield in the experiment was in direct proportion to the method of application of the biological product and the conditions of the growing season. The largest increase in yield - 0.40 t / ha or 14.5% was obtained in the variant with grain processing in combination with double spraying of plants during the growing season, the average yield for the studied period was 3.14 t / ha and was maximum, indicators of economic and bioenergy efficiency was also the best.

To identify microorganisms that can penetrate into the endophytic niche of the grain of barley plants, many years of vegetative experiments were conducted on sod-podzolic soil without the use of mineral fertilizers. In the non-growing season, a biological product, consisting of cellulolytic association of bacteria with genotypic passport, decomposed barley straw. Presowing treatment of seeds was not carried out, therefore, during the growing season; local microorganisms decomposing plant residues could be present in the barley rhizosphere. After six years of rotation of barley plants, the microbiological composition of its seed niche was studied. As a result, it was found that in the seeds of barley bacteria are present in an amount of 240 ± 20 CFU/g of grain. Isolated pure cultures of microorganisms were identified as Cellulomonas gelida, Micrococcus luteus and Bacillus licheniformis by the sequence of ITS fragments of 16S rRNA. These types of bacteria were also present in the used biological product. Based on the research conducted, it can be assumed, that permanent cultivation of barley plants and sowing of seeds of the previous year can contribute to the formation of effective microbial and plant biosystems that are resistant to environmental stress.

Seed Ageing

:Germination capacity and germination energy are usually the most frequently used quantitative parameters of forest tree seed. With seed ageing both parameters decreased and the rate of the collapse is given by tree species, age of tree and its seed and biotic and abiotic factors. Relatively little attention has been paid to the age of seed. As it was found, the longevity of the main tree species remained relatively high, and spruce (Picea abies [L.] Karsten and pines (Pinus sylvestris L.) from the investigated areas across the Czech Republic maintained minimally one third of germination capacity or germination energy during the 10 years with the exception of larch (Larix decidua Mill.) where germination capacity decreased almost to zero after 10 years. Although the germination energy and germination capacity decreased significantly, it is possible to use the seed in the case of shortage of the seed of better quality.
