Abstract | Biocontrol agents and plant
growth-promoting rhizobacteria represent promising tools to improve plant
growth and health as environmentally friendly biopesticides and fertilizers. Streptomyces
bacteria are commonly used for biocontrol, but have been poorly investigated
for biofertilizer activity. In this study, we evaluated at field scale the
performance of rock phosphate (RP) solubilizing Streptomyces spp. (S.
bellus (SB) and S. saprophyticus (SS) in promoting the growth of sugar
beet under RP fertilization. Inoculation of seeds with SB stimulated root
elongation and inoculation with SS enhanced shoot elongation. At the end of the
trial, chlorophyll levels in the leaves were higher with SS. The highest root
yield was recorded with SS, and root diameter increased with both bacteria. The
levels of soil available phosphorus (P) and potassium (K) increased
particularly with SB, but also with SS inoculation. In sum, potassium and
phosphate solubilizing and sugar beet growth promoting activities of SB and SS
were lower in the field than previously observed in the greenhouse. That the
activities were present in the field speaks for improving the formulation and
optimizing the application strategy.
