Isolation and purification of potassium solubilizing bacteria from different regions of India and its effect on crop’s yield
Journal Title: Indian Journal of Microbiology Research - Year 2016, Vol 3, Issue 4
Abstract
Potassium is one of the important component of plant nutrients to meet the requirement of plant’s growth, crop yield and quality of product. Isolates of KSB was carried out using mica (insoluble potassium) from the soil sample of different regions of India basically U.P and M.P on Aleksandrow’s agar media. Out off 14 isolated bacterial isolates 7 bacterial isolates MPS1C2, MPS2C5, MPS2C4, MPS5C1, UPS1C1, UPS2C1, UPS3C1 showed highest D/d ratio 3.13, 3.50, 2.0, 3.22, 5.00, 4.13, 3.75. Optimum pH and temperature was pH-7 and 28±2°C. Maximum K solubilization was achieved in KCl and K2SO4. The isolated bacterial strain was identified as Micrococcus varians and Corynebacterium kutscheri. KSB treated Groundnut plant showed maximum pods of 16 and seeds 72 per plant as compared to control having pods 7 and seeds 21.
