Study of biofertilizer based on enzymatic lysates of plant waste on morphometric parameters of peas at early stages of development

The new biofertilizer is a biotechnological product of the rhizosphere and contains a complex of biologically active compounds similar to substances secreted by plant symbionts in natural conditions with a molecular weight of 304 to 1640 atomic units. Pre-sowing seed treatment with biofertilizer leads to an increase in the germination energy of peas by 15% (maximum) compared to the control and is 100%. The working concentration of 10-3% has the greatest effect. Significant improvement in pea growth rates is observed by the 15th day. The maximum growth of the main root is noted by 2.7 times compared to the control when treated with biofertilizer at a concentration of 10-4%. Enhanced formation of lateral roots in pea sprouts is observed in the experimental variants by 23% higher than in the control. The total length of lateral roots from one plant on the 15th day as a result of treatment reaches 130 cm. In the control variants it is only 24 cm. An increase in this indicator by 5-5.5 times has a beneficial effect on the formation of a branched root surface.
