There could be a variety of things causing this. Most often, flowers fall if there is uneven irrigation, or sudden changes in environment. Can you post a picture of your plant also?

Has it ever given fruit in its lifetime? How often are you watering it? How much NPK? Any other sprays? Location where it is planted?

Wood Ash ... one bath mug per square meter area once a year... 2 inch of cow manure every 4th month around 3 feet diameter from tree...

They look good from what I can see. Do as Izhar bhai says. Water on a consistent schedule- don't let the soil dry too much or overwater. Only water when the soil is one inch dry. Should help iA. Best of luck!
