Abstract

NITRO-FIXING SYMBIOTROPHIC BACTERIA WITH DIFFERENT CHARACTERISTICS

The stimulatory effect of the nodule bacterium Rhizobium on the growth, development and productivity processes in tomato and cucumber plants was studied. It has been established that treating seeds with bacterial metabolites in optimal concentrations (1:300; 1:500) stimulates the growth and accumulation of dry mass of plants. The effect of bacteria on phytoparasitic nematodes – Ditylenchus destructor – was also investigated. Keywords: Bacteria, nematodes, nodules, metabolites, germination, plants, productivity, harvest.
