 ABSTRACT

Field experiment was carried out during 2014-15 and 2015-16 at Main Agricultural Research Station, UAS, Raichur to study the effect of organic manures on microbial biomass and enzymatic activity in bajra groundnut cropping system. The two years pooled data indicated that soil application of organic manures and foliar application of liquid organic manure produced significantly higher micro flora and better soil health compared to the application of inorganic fertilizer. Application of compost + vermicompost + panchagavya recorded significantly higher dehydrogenase (11.25 μg TPF formed g-1 soil day-1) activity and phosphatase activity (61.59 μg PNP g-1 soil h-1). Microbial population such as bacterial population (27.73 × 107 CFU g-1 of soil), fungi (35.23 × 104 CFU g-1 of soil) and phosphorus solubilizers (30.82 × 103 CFU g-1 of soil) was found significant with compost + vermicompost + panchagavya.

Key words: enzyme activity, organic manure, bajra, fungi.
