This study was carried out to evaluate the efficacy of agriculturally beneficial fungi for potash solubilization and to develop myco-potash cultures for use in crop growth. In all six fungal cultures were utilized in the study, viz. Paecilomyces lilacinus, Tricoderma harzianum, Aspergillus wentii, Emericella nidulans, Verticillium lecanii and Tricoderma viride. Among them, A. wentii and T. viride were found to produce 3.3 and 3.65 mm solubilization index around the colony after 7 days of incubation (DAI) on Aleksandrov medium supplemented with mica as potash source. Whereas for agar medium supplemented with feldspar, maximum solubilization index was 2.5 mm (A. wentii), 2.55 mm (T. viride), 2.48 mm (V. lecanii) and 2.58 mm (P. lilacinus) 7 DAI. To reveal the mechanism of potash solubilization, A. wentii, T. viride, T. harzianum and V. lecanii were chosen for organic acid profiling using HPCL. A. wentii produced the highest amount of total organic acid (1847.775 μg/ml).

Abstract


This study was carried out to evaluate the efficacy of agriculturally beneficial fungi for potash solubilization and to develop myco-potash cultures for use in crop growth. In all six fungal cultures were utilized in the study, viz. Paecilomyces lilacinus, Tricoderma harzianum, Aspergillus wentii, Emericella nidulans, Verticillium lecanii and Tricoderma viride. Among them, A. wentii and T. viride were found to produce 3.3 and 3.65 mm solubilization index around the colony after 7 days of incubation (DAI) on Aleksandrov medium supplemented with mica as potash source. Whereas for agar medium supplemented with feldspar, maximum solubilization index was 2.5 mm (A. wentii), 2.55 mm (T. viride), 2.48 mm (V. lecanii) and 2.58 mm (P. lilacinus) 7 DAI. To reveal the mechanism of potash solubilization, A. wentii, T. viride, T. harzianum and V. lecanii were chosen for organic acid profiling using HPCL. A. wentii produced the highest amount of total organic acid (1847.775 μg/ml).
