Abstract : The effects of NAA (10, 20, 30, 40 or 50 ppm), 2,4-D (10, 20, 30 or 40 ppm), 2,4,5-T (20, 40, 60 or 80 ppm), GA3 (50, 100, 150 or 200 ppm) on mango (cv. Amrapali) fruit yield and composition were studied in Jharkhand, India, during 2003 and 2004. The highest fruit yield was obtained with 100 ppm GA3 (9.5 kg per plant). NAA at 20 ppm resulted in the highest concentrations of TSS [total soluble solids] (22.5°Brix), reducing sugars, nonreducing sugars and ascorbic acid, and in the highest total sugar content and sugar:acid ratio (107.1).
