A field experiment was conducted during 2015-16 at Agricultural Research Station, Mudhol, University of Agricultural Sciences, Dharwad to evaluate different methods of irrigation to achieve higher target yield levels in sugarcane. The experiment was laid out in split plot design with 12 treatment combinations and three replications. Among the irrigation methods, subsurface (224 t ha-1) and surface drip irrigation (217 t ha-1) recorded significantly higher cane and sugar yield. Among the target yield levels, significantly higher cane yield was observed with target yield of 200, 250 and 300 t ha-1 than RDF. No significant difference in soil microbial biomass carbon (SMBC) and nitrogen (SMBN) was observed among irrigation methods. However, both SMBC and SMBN decreased gradually with increase in fertilizers levels to achieve higher target yield levels.
