Dragon Fruits in Gujarat, India

I have  a grower  from Gujarat, India that has grown dragon fruits. His problems were  sun burn(excess heat) injury to these plants.  He has given 15:15:15  fertilizer  by drip irrigation and still continue with the same grade. Their  plants are now 12 months old.

He said that their plants have flowered this season and also are bearing few fruits and  would like  suggestions of how and what grade to fertigate and quantity of fertilizer by drip.

He also  asked me whether he could  spray fertilizers to get better quality and size of fruits to these plants? If yes in what quantity and what intervals should I spray?

The problem he said that is it necessary to sprinkle water on the canopy during high temperatures in summer, and can we cover the canopy with a shade net to protect from sun burn? If yes please suggest the color i.e green or white shade net, and should it be 50% or 75% shade net.

These are my answers:

 If your plants had flowers you should change your fertilizers to 12:12:17:2 instead of 15:15:15. If you continue to give the latter fertilizer your plants will have more vegetative growth meaning that your plants will be grow more green shoots rather than flowers.You can boost your plants with foliar fertilizers with high K mixed with fungicides ; spray for every two weeks. Once the fruits came out you should wrap with newspaper envelope to avoid insect attack or cracking.
To avoid scorching, you could cover your plants temporarily with green net  50% shade.
This area is  very dry and needs irrigation. As dragon fruit is heavy feeder it needs high amount of organic matter

Fruits need to be wrapped as it would damage by insects and cracking

This plants need foliar fertilizer as to enhance more branching. Branching will promote more flowers

The planting distant is OK however do not let insect from mango trees attack the fruits.

Note:
Fruit growers may ask me questions or advice. I am obliged to answer wherever I could. Please don't expect for me to answer immediately, or I try to answer to best of my ability. If they have money they could invite to their so that I could give my expertise.
