The field experiment was conducted at Agricultural Research Station, Mudhol, University of Agricultural Sciences, Dharward during the rabi season of 2011 and 2012 (two years) in order to investigate dehydrogenase activity in rhizosphere soils of sugarbeet. The dehydrogenase activity was investigated with sugarbeet genotypes and varied levels of nitrogen and potassium. Three genotypes were evaluated, among them Magnolia recorded significantly higher dehydrogenase activity than other genotypes and the treatment application 100 kg N and K2O recorded significantly higher dehydrogenase activity among the fertilizer N and K2O levels. The interaction effect was found significant. Increased levels of fertilizers decreased the dehydrogenase actitvity (DHA). The DHA was increased from 45 days to 90 days after sowing (DAS).
