Exploitation of phosphate solubilizing bacteria (PSB) and fungi as microbial inoculants is knownrnto promote plant growth through the supply of plant nutrients and supression of pathogens. Inrnview of this, the present investigation was planned to assess the phytobeneficial traits ofrnphosphate solublizing bacterial and fungal isolates recovered from coffee (Coffee arabica) andrnvermicompost to determine their potential in growth promotion of coffee seedlings under lowrninput agriculture.. The microbes were isolated and purified following standard methods. Thernselected isolates were investigated for their plant growth promoting properties, eco-physiologicalrntolerance under laboratory conditions, and further tested under greenhouse and nurseryrnexperiments. The greenhouse and nursery experiments were conducted with completelyrnrandomized design (CRD) in three (3) replications per treatments. Thus, a total of 154 bacteriarnand 72 fungi isolates were recovered from which twelve potent bacterial and nine fungal isolatesrnwere selected and investigated for their plant growth promoting properties. Among the twelvernbacterial isolates, three of them were tentatively identified to the genera of Pseudomonasrn(RCHVCB1) and Bacillus (RScB1.19 and RMaB2.11), and showed significant potential tornsolubilize Ca3 (PO4)2 and posessed several phytobeneficial traits, viz, indole acetic acid, NH3,rnHCN productions and N-fixing ability. They also exhibited remarkable tolerance tornecophysiological factors such as heavy metal, acidity and salinity, and inherent antibioticrnresistance (IAR). Similarly, three fungal isolates with superior phosphate solubilizeation abilityrnwere characterized and identified as genera of Penicillium (RSCF1.19) and Aspergillusrn(RCHVCF2 and RLVCF2). During co-culture, RSCF1.19 (Penicillium sp.) slightly inhibited therntest pathogen, Fusarium xyloriodes. The bacterial (RCHVCB1, RScB1.19, RMaB2.11) andrnfungal isolates (RSCF1.19, RCHVCF2, RLVCF2) enhanced rate of coffee seed germinationrnunder laboratory conditions and promoted coffee seedlings growth under glasshouse conditions.rnThe results of inoculated seeds showed significant (pâ‰¤0.05) differences in germination rate andrnvigor index compared to the control. Isolates RScB1.19, RMaB2.11+RSCF1.19 and RMaB2.11rn+ RLVCF2 showed high germination rate (20.59%) over the control (13.33%). Moreover, arnsingle inoculation of RLVCF2, RSCF1.19 and co-inoculation of RMaB2.11 with RLVCF2 alsornshowed significant (pâ‰¤0.05) mean root length (1.31 cm) and mean shoot length (1.48 cm) overrnthe control. Under greenhouse conditions, single inoculation of RSCF1.19+phosphate and dualrninoculation of RSCF1.19 and RCHVCB1 in the presence of inorganic phosphate fertilizer led tornsignificantly higher plant height, root length, stem girth, leaf number, leaf area, fresh and dryrnweights. Due to high pH value of the potting medium (vermicompost alkaline pH-pH>7.5), allrnthe treatments combined with vermicompost showed suppressive effect and no any seedlingsrnwere emerged at all. Under nursery conditions, co-inoculation of RSCF1.19 with three bacterialrnisolates (RCHVCB1, RScB1.19, and RMaB2.11) in combination with inorganic phosphate led tornsignificantly increase the tested growth parameters. Similar increase in growth attributes wasrnrnobserved in both single and dual inoculations due to vermicompost used compared with bothrnpositive and negative controls. Higher NPK-uptake was observed in a combination of bioinoculantsrnand inorganic phosphate fertilizer compared to the positive and negative control. Inrngeneral, inoculation of RSCF1.19 and RLVCF2 isolates to coffee 74110 variety combined withrninorganic phosphate fertilizer resulted in good vigor and healthier coffee seedlings (RSCF1.19,rn34.42%) and (RLVCF2, 37.09%) when compared to control (28.49%). Therefore, bothrnRSCF1.19 and RLVCF2 fungal isolates could be used as bioinoculants after field trials inrncoffee 74110 variety productions.
