Golden apple (Amra): how much fertilizer per tree?

Urea, TSP and MOP for each age of the tree, from BARC's Fertilizer Recommendation Guide 2024.

Short answer

BARC's Fertilizer Recommendation Guide 2024 gives a young Golden apple (Amra) tree (0–1 years) about 109 g of urea, 199 g of TSP and 100 g of MOP (potash) a year. A fully grown one (over 10 years) needs about 391 g of urea, 623 g of TSP and 362 g of MOP a year. Put the yearly dose on in 4 equal turns: март–април, май–юни, септември и октомври.

Amra, the hog plum. Two tables with different yield goals.

Dose for each age

Find the age of your tree in the first column, counted in years since planting. The figures are grams per tree for one year; the first row is the planting pit. For an orchard, multiply by the number of trees and divide by 1,000 to get kilograms, or let the calculator below do it.

When to apply

Mix it into the planting pit 10–20 days before planting the sapling, then water it in.

Put the yearly dose on in 4 equal turns: март–април, май–юни, септември и октомври.

Put it around the tree under the spread of its branches, leaving some space from the trunk, mix it into the soil and water it in. Young trees get the same turns with smaller amounts.

Using DAP instead of TSP

DAP has the same 46% phosphate as TSP, so use the TSP figure as the DAP figure. DAP also carries 18% nitrogen (about 0.4 kg of urea saved per kg of DAP). The guide does not subtract it and neither do these tables, but you can take it off the urea if you want to.

How these numbers are worked out

BARC's guide gives grams of nitrogen (N), phosphorus (P) and potassium (K) per tree for each age. We convert P to P₂O₅ (× 2.29) and K to K₂O (× 1.21), then divide by what is in the bag: urea 46% N, TSP 46% P₂O₅, MOP 60% K₂O. The guide's amounts are for the whole year; split them as shown under “When to apply”.

These are the guide's general doses for a healthy, well-managed tree, not a prescription for your orchard. Soil, variety, rainfall and crop load change what a tree needs. Check with your local Department of Agricultural Extension or horticulture officer.
