Abstract

The study entitled “Impact of introduced bioinoculants on urease enzyme activity in soil under different levels of drip irrigation and fertigation in sugarcane cultivation” is done to evaluate the effect of bioinoculants (Azospirillum, Phosphobacteria and Potash solubilizers) and different irrigation levels on urease activity and thereby nitrogen recovery by sugarcane plant. In this study sugarcane variety CO 86032 was used with different levels of irrigation (75%, 100%, 125% Recommended dose of irrigation) and fertigation (75% and 100% Recommended dose of fertilizers with different formulations of fertilizers and with or without biofertiliers). Biofertilizers were applied at 30, 60 and 90 DAP. Based on the results obtained from the field trial, Application of 125 percent ETc (I3) showed  maximum urease activity  at 150 DAP and 75 percent RDF as fully water soluble fertilizer + LBF (F5) recorded the highest urease activity and the Interaction of 125 percent irrigation with 100 percent RDF as fully water soluble fertilizer (I3F6) and 100 percent irrigation with 75 percent RDF as fully water soluble fertilizer + LBF (I2F5) showed the highest urease activity.
