Strict field research was carried in the Research Station of Varieties Evaluation in Przecław in 2011–2013. The goal of the research was to observe the reaction of soybean plants to bacterial vaccination – nitragine and initial nitrogen fertilization. The variables were as follows: nitragine, initial dose of nitrogen (25 kg∙ha-1), nitragine with initial nitrogen dose (25 kg∙ha-1) and control object. The weather conditions considerably influenced plant vegetation and seed crop. Method of nitrogen supply, compared with control object, caused a prolongation of particular phases and differentiated biometric features of plants. Samples fertilized with initial nitrogen dose had increased plant lodging as compared with object with nitragine and with control object. Method of nitrogen supply considerably differentiated SPAD and LAI indicators but did not influence MTA indicator. Initial nitrogen fertilization caused an increase of seed number in a pod as compared with control sample and MTN increase as compared with object with nitragine and with control object. Vaccination of sowing seeds considerably increased the number of root nodules. On average roots of soybean plants produced 16 nodules. The yield mainly depended on the year the research was carried on in. Method of nitrogen supply considerably increased soybean yield as compared with the control sample. It was confirmed as well that initial nitrogen fertilization considerably influenced seed crop as compared with the used bacterial vaccination – nitragine.
