Abstract : 15-year-old bearing mango trees (cv. Dashehari) were sprayed twice before flowering (on 5 and 20 Jan.) in both 1978 and 1979 with combinations of urea (0, 3 and 6%) and gibberellic acid (0, 15 and 30 p.p.m.) in a split-plot design trial with 3 replicates. Urea and GA3, singly and in combination, increased vegetative growth, length of panicle, number of secondary branches, duration of flowering, number of flowers per panicle, fruit set, fruit retention and fruit quality, but reduced the sex ratio (staminate/hermaphrodite) of flowers.
