The present investigation entitled “Effect of foliar sprays of nitrogen, potassium and zinc on flowering and yield attributes 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 replication and ten treatments. The results revealed that foliar spray of plant nutrients improved yield parameters over the control. The highest number of flowers per shoot (7.20), fruit set percentage (74.88%), number of fruits per shoot (3.82), fruit yield (16.20 kg/tree), fruit retention (71.16%) and the lowest fruit drop percentage (28.84%) and highest fruit weight (293.33 g), fruit volume (266.66 cm3), fruit length (8.40 cm) and fruit girth (8.67 cm) were recorded in plants sprayed with nitrogen in the form of urea @ 3% followed by plants sprayed with nitrogen in the form of urea @ 4%.
