Abstract : A trial was conducted to study the effect of foliar application of NAA (10, 20, 30 and 40 ppm), 2, 4-D (5, 10, 15 and 20 ppm) and GA3 (50, 100, 150 and 200 ppm) on fruit retention, yield and quality characters of Langra mango. Fruit retention was maximum with NAA 40 pp. Length, width and weight of fruit and pulp were maximum with NAA 40 ppm. GA3 150 ppm recorded maximum TSS while 2, 4-D 10 ppm recorded minimum acidity. The maximum yield (28.90 kg) per plant was harvested under NAA (40 ppm).
