Hi
* The life cycle of mango may be divided into five stages: the nursery, the establishment in the field, the non-bearing period, the bearing period, and the aging trees.
* The nutritional requirements in each of these periods differ.
* Speedy growth of root-stock seedlings and proper establishment of grafts are the chief objectives in nursery.
* At the time of establishment in the field, it is necessary to ensure least mortality.
* The main requirements in the pre-bearing age are rapid growth of the tree and the development of a sound and strong framework.
* During the bearing period, good cropping, regular bearing and high quality of fruit are expected.
* When the trees are aged, rejuvenation or reinvigoration is desired.
* These objectives have to be met by different prescriptions.
Liquid manure @ 225 g plant-1 at fortnightly intervals starting 3 months after planting stones. Grower mixture (4-7-5 or 4-9-3 with 25-30% organically derived N @ of 3.5 to 7.0 g tree-1
12.5 FYM + 2.5 BM + 5.0 WA (5.0 FYM + 0.5 BM + 1.0 WA)
AS = Ammonium sulphate, BM = Bone Meal, MOP = Muriate of Potash, NOC = Neem Oil Cake, SOP = Sulphate of Potash, SP = Super Phosphate, WA = Wood Ash.
Foliar sprays of macronutrients have been used to supplement their soil applications to obtain quick response and to correct deficiencies.
