Abstract: A field experiment was conducted at Instructional Farm, Department of soil science and agriculture chemistry, Post Graduate Institute, MPKV, Rahuri during kharif season of 2019-20 to find out effect of organic manure incubated biochar on soil carbon pools at harvest of maize grown on Inceptisol. The field experiment consist of nine treatments viz., Absolute control, GRDF (120:60:40 kg ha-1 N, P2O5 and K2O + 10 t ha-1 Farm yard manure), GRDF (120:60:40 kg ha-1 N, P2O5 and K2O + 5 t ha-1 poultry litter), Biochar incubated with FYM in 1:1, 1:2 and 1:3 proportion and biochar incubated with poultry litter in 1:1, 1:2 and 1:3 proportion. These treatments replicated thrice in randomized block design. The soil organic carbon fractions were significantly influenced by the biochar incubated with the FYM and poultry litter. The soil organic carbon significantly beneficial at tasseling stage in biochar incubated with FYM in 1:1 proportions (1.06%) and at harvest in 1:3 proportion (0.94%). The biochar incubated with FYM in 1:2 proportion recorded the significantly highest total organic carbon at tasseling (1.59%) and harvest in 1:3 proportion (1.40%). The soil microbial biomass carbon was significantly more in GRDF with 10 t ha-1 FYM at tasseling and harvest (238.79% and 114.52%). The water soluble carbon content at tasseling stage of maize was significant in biochar incubated with FYM in 1:3 proportions (38.0 g kg-1) and at harvest in biochar incubated with poultry litter in 1:3 proportions (34.0 g kg-1). The treatment biochar incubated with FYM in 1:2 proportions was significant at tasseling and harvest for particulate organic carbon (1.58 and 1.47 g kg-1) and potassium permanganate oxidizable organic carbon (1.86 and 1.86 g kg-1).
