Combined use of microbiological preparations and Nano Silicon in oats cultivation

Abstract

The article presents the results of the studies on the combined use of microbiological preparations and NanoSilicon in oat cultivation. Biological products (Fungilex, Bactophosphine, Extrasol, Fitosporine) were used for presowing seed treatment, NanoSilicon – for leaf treatment. Presowing seed treatment with Fitosporine, Bactophosphine, and Extrasol increased the height of oat plants and changedthe panicle length: the height of oat plants after seed treatment with Extrasol was 6.3 cm or 8.3% higher than the control one, with Fitosporine – 5.9 cm or 7.7% higher. Fungilex seed treatment reduced oat height by 6.5 cm, or by 8.5%. Bactophosphine seed treatment did not affect the plant height. While the combined use of seed bacterization and treatment with NanoSilicon decreased the height of oat plants by 1.6-18.7 cm, or by 2.1-22.6%, the stimulating effect of the combined use of Fungilex and NanoSilicon on the growth and height of plants was observed. Seed bacterization with biological products increased the yield of oats. It was greatest when using Extrasol for seed treatment and amounted to 25.9 c/ha, which was 7.0 c/ha higher than in the control option. The leaf treatment with NanoSilicon increased the yield by 2.6-5.4 c/ha. Combined treatment of oat plants with Nanosilicon and Extrasol reduced the yield by 1.6 c/ha. The combined presowing seed treatment with biological products and leaf treatment with NanoSilicon increased the yield of oats by 2.7-5.9 kg/ha compared to the control option due to an increase in the number and weight of grains in the panicle. The highest yield – 26.7 c/ha was obtained when treating seeds with Fungilex and leaves with NanoSilicon (7.8 c/ha or 37.0% higher than in the control option).
