The field experiment entitled was conducted during 2021-22 on an on-going long term experiment which was started since 2006-07 at Soil Research Farm, Department of Soil Science, CCS HAU, Hisar. The field experiment consisted of three tillage treatments i.e. CT-CT (Conventional tillage in both kharif and rabi season), ZT-CT (Zero tillage in kharif and conventional tillage in rabi) and ZT-ZT (Zero tillage in both kharif and rabi season). The experiment also consisted of two cropping systems MW and SW (Mung bean-wheat and sorghum-wheat) and three soil moisture regimes (IW/CPE= 0.60, 0.75 and 0.90) with three replications. The results of the experiments revealed that the sulphur, organic carbon, DOC, MBC and MBN content of the soil were higher under MW than SW cropping system. The highest mean value of sulphur, organic carbon, DOC, MBC and MBN was reported under ZT-ZT followed by ZT-CT and the lowest mean value was under CT-CT under both cropping systems. Similarly, the soil moisture regime M_0.90 reported the highest mean value of available sulphur, organic carbon, DOC, MBC and MBN content followed by M_0.75 whereas the lowest mean value was under M_0.60 under both the cropping system.
