A field experiment was conducted to study “Effect of organic and inorganic sources of NPK and bio-fertilizer on enhancement of growth attributes and chlorophyll content of sweet potato (Ipomoea batatas Lam.)” during Kharif season 2016 at Horticulture Farm, S.K.N. College of Agriculture, Jobner (Jaipur). The experiment consists of 16 treatment combinations viz., organic and inorganic sources of NPK (Control, 100 % RDF, 100 % FYM, 50% RDF + 50 % FYM, 100 % vermicompost, 50 % RDF + 50 % vermicompost, 100 % poultry manure and 50 % RDF + 50 % poultry manure) and bio-fertilizer (Control and Azotobacter) were tested in randomized block design with three replications. Result shows that application of 50 % RDF + 50 % vermicompost significantly increased the vine length at 45 DAP (cm), number of branches per vine at 45 DAP, chlorophyll content in leaves (mg/g) at 50 DAP, leaf area (cm2) at 45 DAP and leaf area index as compared to Control, 100 % RDF, 100 % FYM, 50% RDF + 50 % FYM, 100 % vermicompost and 100 % poultry manure, which was statistically at par with 50 % RDF + 50 % poultry manure. The application of Azotobacter significantly increased all the growth parameters as compared to control.
