Evaluation of the prospects for the use of growth-stimulating complexes of endometabolites of cyanobacteria Arthrospira platensis in soybean cultivation

Abstract

For the first time, data were obtained on the use of the cyanobacteria Arthrospira platensis endometabolite complex and its modifications, fortified (additionally enriched) with nutrients B, Se, and P in soybean cultivation technology, which acted not only as growth regulators, but also as adaptogens to external abiotic stress factors during the growing season of the studied crop. It was found that the use of complexes fortified with phosphorus and selenium in pre-sowing seed treatment (0.6 l/t) and foliar top dressing of vegetative soybean plants in the phase of 1-3 triple leaves provides the greatest increase in grain yield by 0.23 and 0.2 t/ha, or by 10.1 and 8.8% in the indeterminate Mezenka variety, and protein collection at the same time is 1022.5 and 1012.7 kg/ha, respectively.
