Abstract : To optimize the nitrogen requirement of pineapple cv. Kew for main and ratoon crop, grown as intercrop in the mango orchard in laterite soil, an experiment was conducted during 2002-2005. In main crop (1st harvest), application of 18 g N/plant resulted in highest fruit weight and size while best quality fruits were harvested from the plants where 12 g N/plant was applied. In ratoon crop, 14 g N/plant application not only produced heaviest fruit but also resulted best quality fruits. Foliar N, P and K status was maximum in the plant which received 14 g N/plant irrespective of the crop. Considering the ill-effect of excessive use of fertilisers and quality aspect, 12 g nitrogen/plant for the main crop and 14 g nitrogen/plant for the ratoon crop is advocated in Kew variety of pineapple grown as intercrop in mango orchard in laterite soil.
