A field study was conducted at the Research Farm of All India Coordinated Research Project on Long-Term Fertilizer Experiment (AICRP on LTFE), Dr. Panjabrao Deshmukh Krishi Vidyapeeth, (Dr. PDKV) Akola, Maharashtra (India), on an ongoing long-term experiment initiated in 1988-89 under sorghum-wheat cropping sequence in Vertisol. The treatments comprised of different levels of recommended dose of fertilizers (RDF) viz.,50, 100, 150% and RDF in combination with farmyard manure (FYM), FYM alone (10 t ha^-1), RDF devoid of S, RDF along with S @ 37.5 kg ha^-1 and Zn @ 2.5 kg ha^-1, NP, N alone and control. Results revealed that the conjoint use of optimal dose of 100% NPK along with FYM @ 5 t ha^-1 resulted in the highest content of N (1.61 and 0.94% grain and fodder), P (0.37 and 0.33% grain and fodder), and K (1.23 and 1.12% in grain and fodder), as well as the highest uptake of N (54.84 and 94.89 kg ha^-1 in grain and fodder), P (15.64 and 33.91 kg ha^-1 in grain and fodder) and K (40.84 and 114.25 kg ha^-1 in grain and fodder). Whereas the control had the lowest content of N (1.31 and 0.79% grain and fodder), P (0.23 and 0.19% grain and fodder), and K (0.99 and 1.01% in grain and fodder) and uptake of N (4.60 and 9.26 kg ha^-1 in grain and fodder), P (1.77 and 3.84 kg ha^-1 in grain and fodder) and K (4.73 and 11.68 kg ha^-1 in grain and fodder). There exist a significant and positive correlation among nutrient concentrations and uptake by sorghum.
