Abstract

A field experiment was conducted at Agricultural Research farm, BHU during the Kharif season of the year 2017 to evaluate the performance of Potassium Solubilizing Bacteria and doses of inorganic K as well as mineral K (Biotite) on the soil physic-chemical properties of the rhizospheric soil of maize at different stages (30, 45, 60 and at harvest). The Treatments comprises two KMB isolates with separate combinations of RDK and biotite. The result showed that treatment combination with full dose of RDK through inorganic and mineral source of K along with KSB gave higher EC compared to other treatment which is clear through treatments T9, T10, T13 and T14. This implies KSB inoculation help in increasing soil EC. Data revealed that T6 i.e. 100% RDK gave better organic carbon than T5 i.e. 75% RDK & T4 i.e. 50% RDK and even better than T7 i.e. 50% RDK + 50% RDK through Biotite and T8 i.e. 75% RDK + 25% RDK through Biotite.
