ABSTRACT
Microbial consortia play an important role to increase the nutrient use efficiency to crops. From the rhizosphere of banana, areca, eupatoria, agave, parthenium, and cactus plants, two potassium (KSF) and phosphorous solubilizing (PSF) fungi were isolated and screened by using Sperber's and Alexandrove's media. further these were identified as Aspergillus species. The highest phosphate solubilization (1.30cm) and maximum pi release (7.40 %) was observed in (PSF-2) Aspergillus species and lowest solibalization and pi release (0.5cm and 6.30%) was observed in PSF-1. The highest potassium solubilization 2.6cm and maximum potassium release 20.50µg/ml was observed in KSF-2 Aspergillus species and lowest solibalization and release (0.4cm and 10.19µg/ml) was observed in KSF-1 respectively. Therefore, application of KSF-2 and PSF-2 increases the plant height (135 cm at 45 DAT), number of leaves (45/plant) and yield (19 fruits/ plant at harvest). Further, the maximum NPK status in soil after the harvest of the crop (N-356, P- 35 and K-150 kg/ha) as well as NPK content (N-168, P-280 and K-172 mg/plant) in brinjal plant was maximum in the PSF2 + KSF2 + 100% RDF applied soils.
