Abstract: The present study was conducted during 2016-17 to study the impact of manuring and fertilization on soil nutrient status under sorghum-wheat sequence in Vertisol was studied after 29 years in 2016-17. The treatments comprised of 50% NPK, 100% NPK, 150% NPK,100% NPK (-S), 100% NPK + Zn @ 2.5 kg ha-1, 100% NP, 100% N,100% NPK + FYM @ 5 t ha-1, 100% NPK + S, FYM, 75% RDF + 25% N through FYM and Control laid out in randomized block design (RBD). The results of the present study revealed that, organic carbon content of soil was significantly increased under different treatments in sorghum-wheat cropping system with maximum value (7.87 g kg-1) was recorded under 100% NPK + FYM @ 5 t ha-1 (to kharif only) treatment in surface soil and minimum (3.79 g kg-1) under control. Calcium carbonate content in surface soils was significantly affected by long-term application of fertilizer. The calcium carbonate after harvest of wheat was higher (6.47) with the application of 100 % NPK + FYM @ 5 t ha-1 (to kharif only). Available N, P and K content in surface soil was significantly increased with various fertilizer treatments with maximum value i.e. 324, 20.30, and 488 kg ha-1 was recorded under 100% NPK + FYM @ 5 t ha-1(to kharif only). The grain and straw yield of wheat were increased with successive increase in fertilizer level. Significantly higher grain and straw yield was recorded with the application of 100 % NPK + FYM @ 5 t ha-1 (to kharif only) followed by 150 % NPK.
