Abstract: Different sources of nutrients (mahua cake @ 10.4 kg, mustard cake @ 5.1 kg, neem cake @ 5.0 kg, FYM @ 34.7 kg, recommended dose of fertilizer-RDF- 260:320:260g of N: P2O5:K2O, 50% mahua cake + 50 % RDF, 50% mustard cake + 50 % RDF, 50% neem cake + 50 % RDF, 50% FYM + 50 % RDF ) were applied on guava cv.L-49 plant -1year -1 to assess the yield and quality. Application of nutrients irrespective of their sources and doses, markedly enhanced yield and quality of guava fruits over untreated control. The number of fruits, yield and most of the physical and quality parameter like fruit weight, fruit size, pulp weight, total sugar and ascorbic acid content were significantly higher in 50% neem cake + 50% RDF treatment. The plant treated with 50% mahua cake + 50% RDF showed higher TSS (11.0 0Brix), reducing sugar (4.22%) and TSS/acid ratio (33.85). Among the organic sources, mahua cake @ 10.4 kg and neem cake @ 5.0 kg resulted better yield. Better quality fruits was however harvested from FYM treated plants.
