Legume plant yields using biopreparation and plant growth regulators

Abstract

The effect of the biopreparation Rizotorfin and growth regulators Albit, Kornevin, Epin-Extra on symbiotic activity and yield of the bean plant varieties Geliada and Shokoladnitsa was studied under field conditions. The nitrogenase activity was increased in Heliada bean plants after treatment of seeds with Epin-Extra against the increase of bacteroides area, amount and area of volutin and decrease of area and amount of poly-ß-oxybutyric acid (POM). The protective effect of Rizotorfin was evident in the variety Shokoladnitsa. The relationship between symbiotic nitrogen fixation and yield of bean plants of varieties Heliada and Shokoladnitsa was detected. The varietal responses of these plants to the use of Risotorfin and growth regulators have been identified. To increase the efficiency of legume-rhizobium symbiosis and plant productivity, the pre-sowing treatment of seeds with a biopreparation based on nodule bacteria and growth regulators is recommended.
