Abstract: An experiment based on conservation agriculture was conducted to assess the effect of different tillage systems such as zero-tillage (T1), permanent raised bed (T2) and Conventional Tillage (T3) and cropping systems such as rice+wheat (C1), rice+maize (C2) and rice+lentil (C3) on soil microbial biomass carbon (MBC), soil microbial biomass nitrogen (MBN) and soil microbial biomass phosphorus (MBP) were studied in Inceptisol soil in BAU, Sabour, Bihar. Due to change in microbial biomass C, N, P in soil microbial count and biological enzymes in soil influenced and by virtue of which physical, chemical and biological properties imbalanced. Our aim of study to determine how three tillage practices and three cropping systems affect MBC, MBN and MBP content in soil. The result reveals that MBC (583 mg/kg soil), MBN (39 mg/kg soil), MBP (19 mg/kg soil) was highest under T1 with C3 system as compare to other 2 systems of tillage and cropping (403 mg/kg soil), (20 mg/kg soil), (6 mg/kg soil). From this experiment, we observed that among three tillage practices and cropping system combination, zero-tillage (T1) with legume based cropping system (C3) found significantly highest MBC, MBN, MBP as compared to other tillage- cropping combination based systems.
