BIOLOGICAL EFFICACY OF AGROCHEMICAL THE DRAG HOOK BRAND ALTISIMO-L ON SOYBEANS
Examined the effects of organic fertilizer based on amino acids the drag hookbrand Altisimo-L on the growth and production processes, photosynthesis, yield and content in soybean seeds protein and fat. Installed, double treatment of soybean plants (1 in the phase of full shoots, 2 in the budding phase) of the test drug, giving plants optimal diet and increasing the ability of plants to resist and overcome climatic stress, enhances plant growth in height (57,7 - 60,4 cm, control -5,6 cm, NSR <sub>05</sub>- 2,7 cm), branching processes (2,0 -2,1 pcs in the control is 1,8 pc.. branches/plant, NSR <sub>os</sub>-0,1 pcs.) and leaf formation (13,9 - 15,7, in the control-11,0 pcs. leaves, NSR<sub>05</sub>-0,6 pcs.; leaf area-114,2-138,1, in the control-96.0 cm<sup>2</sup> /plant, NSR <sub>05</sub> = 5,6 cm<sup>2</sup>). In the experimental versions, the photosynthetic activity of soy plants significantly increased-the productivity of the leaves (6,1 -6,9, in the control - 5,9 g/dm<sup>2</sup>) and the content of pigments in the leaves (chi. a+b = 2,49-2,81 mg/g cheese, in the control - 2,42 mg/g; carotenoids - 0,38-0,47, 0,37 mg/g cheese). Absolute values of growth indicators, photosynthetic activity of leaves, crop structure, yield and content of protein and fat in soy seeds largely depended on the dose of the drug. They were maximum in the variant with the use of the drug in a dose of 0,4 l/ha (the consumption of the working solution is 300 l/ha).
