Abstract: Fruit growing is an indigenous practice for human being. It is developed and still developing culture for growers. KNO3 applied by aerial spray to the fruit crops improves yield, yield attributing characters and quality parameters. In Mango, the application of KNO3 is effective twice at 1st flower bud differentiation followed by another spray during the full bloom stage with concentration of 1% for flowering, fruiting, yield and quality characteristics. KNO3 spray at last week of October and November at 1.5% increase quality parameters of Ber. In Banana, KNO3 two sprays, 1st spray after complete emergence of bunch and 2nd after 15 days after first spray with 1.5 % increase organoleptic parameters. In Sapota, two application of KNO3 2%, 1st spray at November and 2nd two months after 1st spraying increased fruit retention, yield and physical parameters. KNO3 1.5 % twice (1st spray before flowering and 2nd at fruit set) increase fruit yield and quality characters of Custard apple, while in Guava KNO3 spraying done before flowering, at flowering and after flowering at 15 days interval with 1.5 % increase no. of flowers and fruit retention. Citrus responded well to girdling + 2% KNO3 1st at beginning of April and 2nd at mid- June and KNO3 2% increased juice content. In Pomegranate, KNO3 and K2SO4 twice at last week of April and May increased average fruit weight, yield and TSS. Though, the response of KNO3 was noted different in various varieties of pomegranate. In Papaya, KNO3 2% gave a maximum germination percentage.
