Abstract
Continuous rise in the price of phosphatic fertilizers is causing a burden on the farmers. This experiment was undertaken with the purpose of developing a strategy to utilize and solubilize rock phosphate tailing from Jhamarkotra mines Udaipur District, Rajasthan, India through different combinations with SSP inoculated with phosphate solubilizing bacteria and observed their effectiveness as P source against commercial single super phosphate (SSP) using wheat as the test crop. Control (without P application) and P application through RPT and SSP inoculation through PSB in different combination were also included for comparison. Results shows that application of 50% RDP through SSP and 50% RDP through RPT along with PSB significantly better performed than other treatments in terms of P use efficiency of soil and yield of wheat. This study could help to utilize Jhamarkotra rock phosphate tailing as a P source for wheat, with combination with SSP and seed inoculation with PSB and reduce the dependence on commercial fertilizers like SSP.
