Pot culture experiment was conducted to evaluate the effect of different minisett corm sizes and integrated nutrient management practices on biological properties of potting medium in elephant foot yam at Instructional Farm, College of Agriculture, Vellayani, Thiruvananthapuram, Kerala during April 2018-November 2018. The treatments consisted of three minisett corm sizes (s1-200 g, s2-300 g and s3-400 g) and five integrated nutrient management practices (i1-100 % NPK, i2-75 % NPK with 50 % N substitution through coir pith compost, i3-75 % NPK with 50 % N substitution through coir pith compost + PGPR mix-I + AMF, i4-50 % NPK with 50 % N substitution through coir pith compost, i5-50 % NPK with 50 % N substitution through coir pith compost + PGPR mix-I + AMF) and a control (1 kg). Higher microbial population was observed in the application of 75 % NPK with 50 % N substitution through coir pith compost + PGPR mix-I + AMF both at 5 MAP and at harvest. Dehydrogenase activity was also observed higher in the same treatment both at 5 MAP and at harvest. Lower microbial population and lower dehydrogenase activity were observed in application of 100 per cent NPK as chemical fertilizers, compared to INM practices.
