Abstract

The present study entitled “Effect of foliar sprays of urea, potassium sulphate and zinc sulphate on quality of guava cv. Taiwan Pink” was carried out at Farmer’s field at Manchili village near Athili with the support of Department of Post Harvest Technology at College of Horticulture, Dr. Y.S.R. Horticultural University, Venkataramannagudem, West Godavari District of Andhra Pradesh during 2016-2017. The experiment was laid out in randomized block design with three replications and ten treatments. The results revealed that foliar spray of plant nutrients improved quality parameters over the control. The highest fruit firmness (7.33 kg/cm2), total soluble solids (10.09 0 Brix), total sugars (7.35%), pectin content (0.86%) and ascorbic acid content (235.38 mg /100 g) and lowest acidity (0.35%) was recorded in plants sprayed with potassium sulphate @ 3%.
