Potassium Nitrate, Keitt Mango Plantation and Pruning

[Tropicdude]

Edited this post to include information on the other videos added.

The videos are all in Spanish, but in this 1st clip, you can witness at around 8:38 on the video the results of spraying with KNO3 ( Potassium Nitrate ) , One side of the plantation was sprayed, the other side was "control" and not prayed  trees not sprayed have little to no fruit.

Unlike the subtropics where you get some cold to stress the trees, here in the tropics, it is the dry season that stresses trees, this year there was no dry season. 

KNO3 is usually used to synchronize fruiting on commercial farms, and not just for increasing fruit production.

Finally in this last clip, at another plantation,  you can see how they are going through some major transformation, they had part of the farm planted with Madam Francis mangoes, with intention to export to the USA,  but because of lack of post harvest processing plants in the area, they decided to Topwork all the MF trees and switch them to Keitts.

Also another change is they have decided to make the plantation into a high density farm, and have added trees in between the others,  originally they were 9mX9m now they are 9X4.5M

The powdery substance on the mangoes is Lime, they use it to prevent sunburn on the fruit.
