To improve the soil quality, production, productivity and maximizing profit with higher economic returns through application levels of zinc and sulphur. Factorial randomized block design fallowed here with 9 treatment combinations replicated 3 times. Recommended dose of fertilizers i.e. nitrogen, phosphorus and potassium, was applied @ 20:40:20 kg ha-1as urea (46% N), single super phosphate (16% P2O5), muriate of potash (60% K2O) and zinc sulphate (33% Zn). Application levels of sulphur 0, 15 and 30 kg ha-1 and zinc 0, 1.5 and 3.0 kg ha-1 at 5 cm depth in furrows, before seed sowing was done with spacing of 30 X 10 cm. The accumulative mean of low soil pH (6.85) by T9 - (Zinc@100%+ Sulphur@100%), electrical conductivity (0.22 dS m-1) by T6 - (Zinc@50% + Sulphur@100%), particle density (2.64 mg-3) by T5 - (Zinc@50%+ Sulphur@50%) and bulk density (1.16 mg-3) by T4 - (Zinc@50%+Sulphur@0%), the higher available nitrogen (273.67 kg ha-1) by T9 - (Zinc@100% + Sulphur@100%), available phosphorus (16.49) by T8 - (Zinc@100% + Sulphur@50%), available potassium (128.34) by T9 - (Zinc@100% + Sulphur@100%), available zinc (1.30) by T9 - (Zinc@100% + Sulphur@100%) and available sulphur (19.83) by T9 - (Zinc@100% + Sulphur@100%). The combined application of zinc and sulphur along with control, has led to improvement in soil health potential, nutrient availability and yield sustenance under Black gram crop cultivation in which found that the treatment (T9) consisting of zinc (100%) + sulphur (100%) give best result among other treatments.
