Experimental results revealed that application of both levels 75 and 100% of recommended dose of NPK in combination with FYM and sulphur both significantly improved the soil properties and residual fertility. The Organic carbon content of soil increased from 2.2 to 3.4 g kg-1 soil, water holding capacity (WHC) improved from 42.45% to 44.87%, available–N from 147.6 to 224.1 kg ha-1, available–P from 8.6 to 17.9 kg ha-1, available-K from 81.0 to 126.9 kg ha-1 and available-S from 16.2 to 21.8 kg ha-1 with the application of 100% RDF of NPK combined with FYM and sulphur. A highest residual available-N content 225.1 kg ha-1 with the treatment consisting of 100% RDF of NPK combined with FYM, highest residual available-P18.6 kg ha-1 was obtained with the application of 100% recommended dose of NPK alone and residual available-K of soil i.e. 129 kg ha-1 was recorded with the treatment 100% RDF of NPK combined with sulphur alone whereas residual available-S 21.8 kg ha-1 was found highest with treatment consisting 100% RDF of NPK combined with both FYM and sulphur. A positive balance of available N, P and K and S were recorded in the soil by using with NPK, FYM and sulphur combinations. The highest net gain of NPK i.e. +34.0, +11.10 and +24.0 kg ha-1 respectively, were recorded from treatment 100% RDF of NPK in combination with FYM and sulphur whereas, a maximum net gain of sulphur +5.2 kg ha-1 was recorded with the application 75% RDF of NPK in combination with FYM and sulphur both whereas pH, ECe and bulk density are concerned during this experiment, these parameters were not significantly influenced.
