The field experiment to study the “Comparative efficiency of groundnut haulm compost and biofertilizers on soil physico chemical properties and microbial population of soil was conducted in Arunagirimangalam village, Thiruvanamalai Disrtict. Treatments were groundnut haulm compost single, combined application of different Biofertilizers FYM, Azotobacter, Azospirillum, Phosphobacteria, Rhizobium and control. The obtained results on physiochemical properties of soil and microbial properties revealed the response of groundnut haulm compost, groundnut haulm compost mixed with different biofertilizers a treatment was better compared to control in 15, 30, 60 and 90 DAS observation. Physical properties such as pH and EC increased after groundnut haulm compost mixed with Rhizobium application. Bulk density was reduced after treatment indicating increased soil organic carbon, NPK content, macronutrients (Fe (Iron), Mn (Manganese), Cu (Copper) and Zn (Zinc)) and microbial population. The minimum physiochemical and microbial properties were observed in control. In general, the groundnut haulm compost and mixed with Rhizobium treatment a good performance could be achieved in better growth of groundnut.
