Ahmednagar (MS). The experiment was laid out in FRBD (Factorial Randomized Block Design) with two replications. The trees of custard apple sprayed with 1% and 2% CaCl₂, 1% and 2% CaNo₃ and 1% and 2% KNO₃ at 60, 90 and 60-90 days after fruit setting and control trees was spray with water. The maximum fruit weight (244.80 and 260.70 g), fruit volume (212.37 and 226.16 cc), fruit length (7.16 and 7.62 cm), fruit breadth (8.71 and 9.28 cm), fruit pulp (42.09 and 44.68%), fruit firmness (27.50 and 28.87 N), while minimum fruit rind (47.92 and 51.17%), fruit seed (5.16 and 5.49%) showed significant result with treatment combination C₆T₃ (KNO₃ 2% at 60 and 90 days after fruit set).
