Abstract

Pot and field experiments on small plots were carried out to study the effect of isolates ofPseudomonas fluorescens-putida bacteria, applied to potato tubers, on the growth response of potato plants. Inoculation of tuber pieces with the isolates in pot experiments caused a better growth of young potato plant (111 % increase). The effect depended on the viable count in the bacterial suspension and on growth conditions of the plants. Inoculation of potato seed pieces before planting in field experiments caused a 4 –30 % improvement in plant growth and tuber yield. The complex action of inoculation with rhizobacteria apparently caused changes in the microflora colonizing the roots and stolons, which in turn brought about a better growth and yield.
