Abstract : An experiment was conducted to study the effect of different levels of nitrogen on fruit weight, size, quality and nitrogen content in D leaves of pineapple cv. Kew grown as intercrop in the mango orchard in laterite soil in Jhargram, Paschim Midnapore, West Bengal, India, during November 2001. Application of 18 g N/plant/year resulted in the highest fruit weight and size, while the best quality fruits (having highest total soluble solid (TSS):acid ratio of 16.2) were obtained from the plants which received 12 g N/plant where D leaves showed N value of 1.3%. Considering the lowest N dose (out of 12, 14, 16 and 18 g) and best quality aspect (highest TSS:acid ratio), 12 g nitrogen/plant/year is recommended in kew variety of pineapple grown as intercrop in mango orchard.
