An investigation was carried out to standardize the organic production protocol for cultivation of pineapple cv. Kew. In this investigation pineapple suckers cv. Kew were planted at 64000 plants/ha and the different sources of organic manures (vermicompost at 43.2 kg/plot, farmyard manure at 60.48 kg/plot/year, poultry manure at 21.6 kg/plot/year, neem cake at 20.44 kg/plot/year) and biofertilizers (azotobacter, azospirillum, phosphorous solubilizers and potash mobilizers each at 100 g/plot/year) were compared alone and in combination. The rates of organic manures were decided based on the 50 per cent of the potassium requirement of the crop for the region. Biofertilizers in combination with different organic source of manures like farmyard manure, neem cake and vermicompost proved effective in increasing yield and improving fruit quality of pineapple. Considering the yield and quality of fruit, it may be suggested that for cultivation of pineapple cv. Kew organically, application of poultry manure at 21.6 kg/plot/year (857.14 kg/ha) + azospirillum + phosphorous solubilizers + potash mobilizers each at 100g/plot/year (T13) in two splits (January and July) with a benefit: cost of 2.67 can be practiced under the alluvial plains of West Bengal conditions.
