EFFECT OF PEAT-BASED HUMIC FERRTILIZER “GUMOSTIM” ON PRODUCTIVITY AND GRAIN QUALITY OF OATS

Abstract

Results are given from experiments on treating oat seeds and vegetating plants with peat-based humic fertilizer. The experiments were conducted in 2009-2014 in breeding crop rotation of the Narym Department of Breeding and Seed Production, Siberian Research Institute of Agriculture and Peat, located in the taiga zone of Western Siberia (Tomsk Region). The object of study was oat varieties Togurchanin and Narymskiy 943, and peat-based humic fertilizer “Gumostim” in 0.001 percent concentration of humic acids. It has been found that “Gumostim 0.001” has a positive effect on technological characteristics of oats: thousand-kernel weight increased by 0.3-3.7 g, accumulation rate of crude protein by 0.2-0.4 percent, except for cold and excessively moistened conditions of growing; chaff reduced by 0.1-1.9 percent, except for hot and dry conditions of growing. As a result of treating seeds with “Gumostim”, the yield of oat grain increased by 0.03-0.21 tonnes per ha. The analysis of yield structure has shown that after treating with “Gumostim 0.001” the height of haulm stand increased by 1-5 cm, grain content of the panicle by 3-5 kernels, length of the panicle by 1 cm, except for hot and dry years. Treatments with “Gumostim” had almost no effect on the length of the growing season (-1 day) and resistance of plants to lodging (+0.2 point). Under any weather conditions, treatments with ”Gumostim 0.001” improved the phytosanitary condition of seeds (by 2.1-10.5 percent). Treatments with ”Gumostim 0.001” had a weak effect on the length of the growing season and resistance of plants to lodging.
