Influence of pelleted organo-mineral fertilizers application at seeding on the yield of oats and maize herbage | Влияние припосевного внесения гранулированных органоминеральных удобрений (ОМУ) на урожайность овса и зеленой массы кукурузы

anglais. The study was conducted in 2019 in the Altai region. A pelleted organo-mineral fertilizer was made from litter manure bio-compost with using of Sanvit- K biological product (100 g t). The fertilizer contained 68.5% of organic matter, humic compounds (12.9%), total nitrogen (1.94%), phosphorus (0.56%) and potassium (2.72%). Its application under oats at rates of 0.1, 0.15, and 0.25 t ha at sowing increased the yield from 2.16 t ha to 2.4-3.18 t ha, or by 11.1-17.2%, and the protein content from 14.8% to 11.2-15.3%. When nitrogen-phosphorus-potassium fertilizer was applied, these indices were 2.35 t ha (8.9%) and 11.1%. After pre-planting application of this fertilizer for maize at a rate of 0.05 t ha, the yield increase made 7.7 t ha, or 23% as compared to the control. The green herbage contained 20% of dry matter, 12.1% of protein, 20.5% of fiber, 3.2% of ash, 1.04 fodder units per 1 kg of forage and 11.31 MJ as compared to 18.5%; 10.7; 16.5; 1.0; 17.7; 12.03, respectively, of those in the control. In the fertilized variant more ears in one plant were formed – 3.16 against 2.28, and the proportion in the total biomass increased from 40.4 to 48.6%. The application of pelleted organo-mineral fertilizers at the dose of 5 dt/ha increases the yield of corn herbage by 23% and achieves producing a high quality feed.

russe. Исследование проводили в 2019 г. В Алтайском крае. Из биокомпоста подстилочного навоза с использованием биопрепарата "Санвит-К" в дозе 100 г/т получено гранулированное органоминеральное удобрение с содержанием органического вещества 68,5%, гуминовых соединений 12,9; общего азота 1,94; фосфора 0,56; калия 2,72%. Его внесение под овес в нормах 1,0; 1,5 и 2,5 ц/га при посеве повысило урожайность с 2,16 до 2,4-3,18 т/га, или на 11,1-17,2%, и изменило содержание белка с 14,8 до 11,2-15,3%. При внесении азофоски эти показатели составили 2,35 ц/га (8,9%) и 11,1%. При допосевном внесении под кукурузу в дозе 0,5 ц/га прирост урожайности составил 7,7 т/га, или 23%, к контролю. Зеленая масса содержала: 20% сухого вещества, 12,1% протеина, 20,5% клетчатки, 3,2% золы, 1,04 к.ед. в 1 кг корма и 11,31 мДж против 18,5; 10,7; 16,5; 1,0; 17,7; 12,03% соответственно на контроле. По удобренному варианту образовалось больше початков на 1 растении – 3,16 против 2,28 шт., а доля в общей биомассе увеличилась с 40,4 до 48,6%. Применение органоминеральных удобрений в дозе 5 ц/га обеспечивает повышение урожайности зеленой массы кукурузы на 23% и получение высококачественного корма.
