Abstract
This study was to explore the beneficial interactive effects of fungal inoculum alone or in conjunction with phosphatic fertilizer on maize (Zea mays L.). We conducted a greenhouse pot experiment in soil which included four treatments such as control, Penecillium oxalicum, Aspergiilus niger, P. oxalicum + A. niger at three different levels of phosphatic fertilizers (0, 100, and 200 mg kg-1). The plant height, fresh weight of root/shoot biomass and dry weight of root/shoot biomass and soil chemical properties were recorded. We evaluated the growth parameters of maize and phosphorus (P) uptake in maize were highest in treatment I3 × F2 (Penecillium+Aspergillus + 200 mg P kg-1) followed by I2 × F2 (Aspergillus + 200 mg P kg-1) over rest of the treatments. The beneficial effect was decreased where alone fertilizer dose was added as compared to those where it was added with the co-inoculation of phosphorus solubilizing fungi (PSF). It was observed that soil pH, total organic carbon and available P significantly changed because of various treatments. Based on these evidences, it could be inferred that increasing the maize growth by fungal culture improves soil P fertility, which is favorable to succeeding crops. Further research is needed to understand the chemistry of co-inoculation of fungal inoculum with phosphatic fertilizer. © 2022 Friends Science Publishers
