Abstract:
The field experiment conducted during kharif 2017 at the Department of Entomology, College of Agriculture, OUAT, Bhubaneswar on the efficacy of silicon applied on rice through inorganic and organic sources either alone or in combination with bio fertilizers on dehydrogenase and microbial population revealed that out of twelve treatments the treatment RHA+PF+KSB and CaSiO 3 +PF+KSB supported higher population of bacteria, CaSiO 3 +KSB and RHA+KSB supported higher population of fungus and CaSiO 3 +PF+KSB and CaSiO 3 +PF supported higher population of actinomycetes, RHA+PF+KSB and RHA+KSB treatments contained higher amount of dehydrogenase activities at vegetative and reproductive stage, respectively. The total bacteria, fungal and actinomycetes population was positively and significantly correlated to dehydrogenase activity at both the stages of rice crop.
