Abstract: The article discusses the results of laboratory studies to determine the effect of the introduction of bio-preservatives AiBi 15.10 F and BIO-SIL during silage of corn and sugar sorghum. The dependence of biochemical processes during silage on the type of bio-preservative was revealed, which in turn had a positive effect on the course of lactic acid fermentation. Bioconservative AiBi 15.10 F promoted a more intense accumulation of lactic acid in comparison with BIO-SIL and the control experiment. We saw a high… Show more

The results of studying the productivity of sorghum crops under different conditions of mineral nutrition on meadow-chernozem soil of the southern forest-steppe of Western Siberia are presented. The study was conducted in 2019–2022 in the Omsk region as part of a long-term stationary field experiment. The soil of the experimental plot is meadow-chernozem moderately deep heavy loamy soil. The arable horizon is characterized by neutral reaction of the soil solution (pH 7.0–7.2). The scheme of the experiment is two-factor, includes application of nitrogen (N0, 30, 60) and phosphorus (P0, 60) mineral fertilizers before sowing sorghum crops. The dynamics of moisture content in the meter soil profile is closely related to the hydrothermal conditions of vegetation periods. In the most wetted year of 2019, the soil profile had a more stable and uniform moisture content, especially in the second half meter. In subsequent years, the atmospheric moisture deficit was clearly manifested in the content of total moisture both along the soil profile and in time. Drying out of the meter profile even in the initial growing season was observed in 2022, which can be considered as a result of low residual moisture in the preceding, also dry, season. In the control, mineral nutrition was limited by the low content of mobile phosphorus. The studies have shown that in conditions of insufficient and unstable moisture, typical for the south of Western Siberia, it is advisable to cultivate sorghum crops with high responsiveness to the use of mineral fertilizers in field fodder production. In the average of two years, the maximum yield of green mass of sugar sorghum on intensive background was 21.07 t/ha, sorghum-sudangrass hybrid – 16.62 t/ha, which is higher than the control by 47.2 and 62.7%, respectively. The most effective was the complex application of mineral fertilizers, which provided an increase in dry matter content of sugar sorghum from 3.97 to 6.08 t/ha (53.0%), sorghum-sudangrasas hybrid – from 2.81 to 4.73 t/ha (68.3%).

Relevance. This article presents the results of assessing the biochemical parameters and aerobic stability of silage prepared from the domestic early ripening corn hybrid Ross 195 (FAO 180) in the phase of milky-wax ripeness of the grain. Green mass was carried out during harvesting at Barybino LLC in August 2021.Methods. Ensiling was carried out in laboratory conditions of the Federal Williams Research Center of Forage Production & Agroecology in four variants of treatments with various preservatives in three replications of each.Results. Quality indicators were monitored after 30 and 60 days of conservation. Seven days after opening the containers during outdoor storage in silage variants with the addition of biological inoculants, a slight decrease in the concentration of lactic acid and an increase in acetic acid were determined. In silage with chemical preservative, the acid content remained at the same level. The results of assessing the dynamics of silage heating during outdoor storage allow us to conclude that the aerobic stability of the feed with biological inoculants is sufficient, versus control. At the same time, best preservation (over a period of up to 135 hours) the best aerobic stability of silage was obtained with chemical preservative, which was characterized by higher quality indicators in terms of the level of active acidity (pH 4.0–4.1), ammonia content (0.0055–0.0078%) and sugar, and the quantity and ratio of organic acids remained at the level determined at opening.
