Abstract: The experiment was conducted at Dr. PDKV, Akola during Mrig season 2015-16 and 2016-17. Fourteen-year-old healthy plants of uniform growth of Nagpur mandarin were selected from the field of All India Coordinated Research Project (Fruits). The experiment was conducted in Randomized Block Design with ten treatments which were replicated three times. The experiment consisted of different treatments of cow dung slurry, biogas slurry, fermented cow dung slurry, bio-fertilizers and NPK. The highest fruit yield (36.99 tons ha^-1) was recorded in treatment of fermented cow dung slurry @ 60 L plant^-1 + 75 per cent RDF i.e. 900:300:300 g NPK plant^-1 (T₈) followed by T₇ (34.22 tons ha^-1). The minimum fruit yield was obtained from treatment of fresh cow dung slurry @ 120 L plant^-1 + Azotobacter + PSB (22.66 tons ha^-1). Economic analysis also revealed that the gross returns (Rs. 1108550/ha) and net returns (Rs. 849423/ha) were higher in T₈. Benefit-cost ratio (BCR) was also higher in T₈ (3.28).
