The investigation was undertaken during kharif season 2016 at Shaheed Gundadhoor College of Agriculture and Research Station, Jagdalpur (Chhattisgarh). The experiment was laid out in a factorial randomized complete block design with the treatments comprised of four levels of fertilizers (N0P0K0, N30P20K30, N60P40K60 and N90P60K90 kg ha-1) and four levels of vermicompost (0, 10, 20 and 30 t ha-1) and three replications. Application of vermicompost up to 20 t ha-1 and fertilizers up to N60P40K60 kg ha-1 had significant effect on content and uptake of nitrogen, phosphorus and potassium except potassium uptake by tuber and haulm which was increased successively with increased fertilizers and vermicompost levels, respectively. The total uptake of NPK by tikhur ranges from 43.2-127.0, 18.3-32.9 and 59.9-113.6 kg ha-1, respectively due to varying levels of organic and inorganic nutrients. The interaction effect of fertilizer with vermicompost was found significant in case of nitrogen uptake by tuber and total nitrogen uptake only. The combination of fertilizer @ N60P40K60 with vermicompost @ 20 t ha-1 is found superior as it recorded N uptake either higher or at par with other combinations and also saves cost on fertilizer and vermicompost.
