Abstract : To determine the suitable chemicals for induction of flowering in pineapple (cv. Giant Kew) grown as intercrop, an investigation was performed in a private mango (cv. Vastara) orchard in Jhargram, Paschim Midnapore of West Bengal, India during 2003-04. Treatments consisted of: 4 ml planofix + 300 g urea in 15 litres of water; 300 g calcium carbide + urea; 2 g dry calcium carbide/plant; and a control. The 50-ml solution of Planofix (0.27 ml/litre) + urea (20 g/litre) per plant was effective for induction of flowering in December and January (with 82 and 86% induced flowering). In March, April and May, the calcium carbide + urea treatment was the most effective (61, 23 and 23% induced flowering). In the month of June, dry calcium carbide at 2.0 g/plant showed the best results (i.e. 41% induced flowering) among the treatments.
