Abstract: The field experiment was conducted at the All India Coordinated Research Project on Potato , Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh during Rabi 2013-2014 in factorial randomized block design with fifteen treatment combinations consisting of different levels of RDF as (75%, 100% and 150% NPK) and different organic fertilizers as (FYM, PSB and Azotobacter) were replicated three times. Among the inorganic fertilizer treatments 150% RDF performed better over other treatments, while in case of organic fertilizer treatments PSB + Azotobacter was found superior than others. The interaction between organic and inorganic fertilizers was found differ non significantly. The results indicated that the highest gross return (Rs 271480 ha-1), net return (Rs 192827.52 ha-1) and benefit: cost ratio (Rs 2.45) was obtained under 150% RDF with PSB + Azotobacter.
