The effects of organic manures and biofertilizers on soil physico chemical and biological properties were evaluated during rice-rice fallow blackgram cultivation studies. The experiments were arranged in a completely randomized block design manner with three replications. The soil samples were analysed and plant growth measurements were observed during the initial and final stages. Impact of various natural supplements like azospirillum/rhizobium, phospobacteria, vermicompost, panchagavya 3% and NPK 75% on physico-chemical and biological properties that occurred during the field application studies of rice-rice fallow blackgram were observed.
