Abstract : An investigation was undertaken to known the effect of different organic and inorganic sources of nutrients on quality fruit production of pineapple grown as intercrop in mango orchard in laterite soil. There were nine fertiliser treatments adopting Randomized Block Design having three replications. In each replication there were 50 plants. The manures and fertilisers were applied in six splits and first split was made at the plant age of 2 month. The treatment included as yearly application of vermicompost 60 g 120 g, and 180 g/plant; mustard cake 60 g, 120 g/plant; two different dose of bone meal and wood ash; practiced followed by the farmers and recommended dose of chemical fertilisers (RDF). The results indicated that application of vermicompost @ 180 g/plant/year resulted in less plant mortality, earliness in flowering; better plant growth and produced maximum weight table fruits (1770 g), highest pulp and juice percentage with better in fruit quality in terms of TSS and ascorbic acid content. The plants fertilised with chemical fertilisers or mixed with organic manures produced lower weight table fruits having poor in fruit quality as compared to organic fertilised plants.
