Interactive effect of liquid formulations containing available and unavailable forms of phosphorus source on nitrogen efficiency in aerobic rice

Abstract

Green house experiment was studies to explore the effect of thus developed liquid formulations from previous experiments of above authors and the respective lignite based formulations in the presence and absence of nutrients and at two forms of available and unavailable form of phosphorous (KH2PO4 and North Carolina Rock Phosphate (NCRP)) on aerobic rice variety MAS-26. As a result, higher root nitrogen concentration was observed in P. fluorescens liquid formulation and also in the plants received P as KH2PO4. However, there was significantly higher root N content was observed in plants inoculated liquid formulation of P.fluorescens. Whereas, liquid P. fluorescens and Azospirillum showed highest total nitrogen content.
