Summary:

Crop management systems influence plant productivity and nutrient use efficiency, as well as plant growth-promoting rhizobacteria (PGPR), which are known to influence the growth of plants via phytohormone production, phosphate solubilization, nitrogen (N) fixation and antimicrobial activity. The objective of this study was to compare the influence of two crop management system on microbial PGPR features. PGPR isolated from the rhizospheres of Carica papaya L. grown under two distinct management systems (conventional and organic) were identified and characterized. The 12 strains most efficient in solubilizing inorganic phosphate belonged to the genera BurkholderiaKlebsiella, andLeclercia. N fixation was observed in the strains B. vietnamiensis from the conventional farming system and B. vietnamiensisB. cepacia and Leclercia sp. from the organic farming system. The B. vietnamiensisB. cepaciaKlebsiella sp. and Klebsiella sp. isolates showed antifungal activity, whileLeclercia sp. did not. The strains B. vietnamiensis and Enterobcter sp. (isolated from the conventional farming system) and Klebsiella sp. (isolated from the organic farming system) were efficient at solubilizing phosphate, producing phytohormones and siderophores, and inhibiting the mycelial growth of various phytopathogenic fungi (Botrytis cinereaPestalotia sp., Alternaria sp., Phoma sp., Fusarium culmorumGeotrichum candidum). Physiological differences between the isolates from the two crop management regimes were distinguishable after 10 years of distinct management.
