Study of the parameters and operating modes of the installation for aerosol treatment of seed grain

Pre-plant treatment of barley seeds with hot mist of biopreparations has some protective effect against harmful microflora, improves the absorption of nutrients from the soil, and increases the physiological activity. For pre-plant treatment of barley seeds of “Creshendo” variety, hot mist of the following biopreparations was used: Baktofit, Potassium humate, Fitosporin M, Innopraktika complex. The evaluation of the influence of the treatment was carried out according to the elements of the structure of the yield of plant samples and the physical-chemical indicators of grain samples from experimental plots. The statistical assessment showed good reliability (coefficient of variation was about 10). The number of productive stems per 1 m2 was increased by the hot mist treatment with Innopraktika complex by 54.1 % and Fitosporin M by 31.0 % in comparison with the samples from the control plot. The weight of 1,000 grains exceeded by 5.9 % in samples treated with Potassium humate and by 4.6 % with Fitosporin M. The highest biological yield was achieved when hot mist treatment with Innopraktika complex (50.822 dt/ha) and Fitosporin M (43.17 dt/ha). In terms of physical-chemical indicators, the best values were obtained when treated with Fitosporin M and Potassium humate in comparison with control samples: an increase in the mass fraction of starch in grain was by 10.8 % and 5.1 %, respectively; crude protein increased by 5.4 % and 6.9 %; an increase in the exchange energy in both cases was by 0.8 %. The best effect of pre-plant treatment of barley seeds of “Creshendo” variety is achieved with the use of hot mist of biopreparations Fitosporin M and Innopraktika complex.

The influence of tillage methods on the yield of oilseeds of the Brassicaceae family

2022

The analysis of productivity studies of spring oilseeds of the Brassicaceae family during their cultivation on gray forest soil in the crop rotation link in Ryazan region, Russia is proposed. The influence of variants of the main tillage on the yield of spring rape variety Ratnik and spring rape variety Lipchanka has been studied. The experiments were carried out in 2015-2020 on dark gray forest soils. Agrotechnical measures for the cultivation of spring oilseeds are typical for the Non-Black Earth Zone of Russia, which includes Ryazan region. On average, according to the research results, the highest yield in spring rape was recorded on the variant of the fallow link of the crop rotation + moldboard processing (3.13 t/ha), in the spring rape (2.56 t/ha). When determining the biological activity of the soil, the method of linen with a density of 150 g/m2 was used. In the experiment, on the variant with the moldboard method, when using a reversible plow, the degree of decomposition of the linen was the greatest in the experiment. In agrocenoses of agricultural crops, a pattern was noted for an increase in biological soil activity, in rape the degree of decomposition was recorded in 45.3 % and in spring coleseed it was 41.9 %.

“…The export of wheat grain is one of the significant budget revenue items in Russia. Therefore, the search for new elements of grain production technology that can increase both crop yields and grain quality is quite relevant [1][2][3].…”

Effect of iron nanopowder on the physiological resistance of winter wheat to low temperatures

2022

This paper shows the effect of iron nanopowder on productivity and physiological and biochemical processes, the metal is used at an optimal concentration of 1 g per hectare (seeding rate) of winter wheat variety Moskovskaya 56. Iron nanopowder is quite effective in dressing winter wheat before sowing. At the same time, it increases the length of the roots of experimental winter wheat plants by 22.8%, and also increases the dry weight of plants by 8.9%, which is associated with its biocatalytic properties. The effect of iron nanoparticles on the accumulation of water-soluble polysaccharides in winter wheat plants during the tillering period before the winter period was studied. Iron nanopowder increases the accumulation of polysaccharides in the whole plant by 4.2%, in the tillering node by 4.6%, in the roots - by 0.7%, these changes increase the winter hardiness of winter wheat. It is shown that iron nanopowder increases the yield of winter wheat grains by 19.7%, the weight of a thousand grains by 7.5%, the number of spikelets in an ear also increased by 13.3% and the number of grains in a spikelet - by 14.5% higher than control . Under the influence of the optimal concentration of iron nanopowder, the chemical composition of wheat grain changes, the content of gluten in the grain increases by 2.0% and its quality index, and the ash content of grain also slightly increased (+0.2% higher than the control). Based on the results of the research, it is possible to recommend the introduction of iron nanopowder into the production of winter wheat.
