title: Symbiotic efficiency of nodule bacteria strains on legumes
abstract: Nowadays, ecologization is one of the important tasks for agriculture. Microbiological preparations based on nodule bacteria application in agriculture is a significant part of organic crop production. Symbiotic efficiency of 13 nodule bacteria strains from the Crimean collection of microorganisms of the FSBSI “Research Institute of Agriculture of Crimea” (http://www.ckp- rf.ru/usu/507484/) was studied in our research. In laboratory conditions, we established that four strains of Rhizobium legum
