Impect Of Potassium Nitrate On Fruit Crops

Potassium Nitrate primarily used where its unique composition and properties can provide specific benefits to growers. KNO3 mostly 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 & 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 orgenoleptic parameters. In Sapota, two application of KNO3 2 %, 1st at Nov. & 2nd two months after 1st spraying increased fruit retention, yield & physical parameters. KNO3 1.5 % twice increase fruit yield & quality characters of Custard apple, while in Guava KNO3 spraying done before flowering, at flowering & after flowering at 15 days interval with 1.5 % increase no. of flowers & fruit retention. Citrus responded well to girdling + 2% KNO3. In pomegranate Kno3 increased fruit weight, yield & TSS.
