In this guide
For a durian NPK purchase, start with tree age and the current programme used for that orchard. The old schedule gives a historical formula comparison by age group, but does not show that a product marketed as “Grower” matches it. If current guidance calls for a balanced or other formula, compare labels that actually match those directions; a marketing name alone is not enough to choose a bag.
What does NPK Grower mean for durian?
“Grower” is a name used on some products, not a standardized NPK ratio. Read the declared N, P and K, additional nutrients, product form, rate units and directions on the actual label. Two bags with the same marketing name may have different contents or directions.
What does the 2004 DOA durian schedule show?
The Department of Agriculture Peninsular Malaysia’s 2004 Durian Technology Package, Table 5, lists compound fertilizer per tree per year and application counts by tree age. This old schedule is not a current orchard rate and does not confirm any “Grower” product sold today [source].
| Table 5 age | Printed formula | Compound fertilizer (kg/tree/year) | Applications/year | Organic fertilizer (kg/tree/year) |
|---|---|---|---|---|
| Year 1 | 15:15:15 | 0.5 | 6 | 20 |
| Year 2 | 15:15:15 | 1.0 | 4 | 30 |
| Year 3 | 15:15:15 | 2.0 | 4 | 40 |
| Year 4 | 15:15:15 | 3.0 | 4 | 40 |
| Year 5 | 12:12:17:2 | 4.0 | 4 | 40 |
| Year 6 | 12:12:17:2 | 5.0 | 4 | 40 |
| Year 7 | 12:12:17:2 | 6.0 | 3 | 40 |
| Years 8–25 | 12:12:17:2 | 9.0 | 3 | 40 |
Derived formula grouping: the four separate rows for years 1, 2, 3 and 4 each print 15:15:15; the rows for years 5, 6, 7 and 8–25 each print 12:12:17:2. This grouping by printed formula is our summary of the source table, not a verbatim age band; each row retains its own annual total and application count [source]. The schedule separates annual totals from application counts. Do not divide an annual figure into per-application doses or apply it to a current product without guidance covering that product and orchard.
What should you check on the label?
Record the full product name, printed N-P-K and other nutrients, net weight, named crop, rate and units, frequency, method and warnings. Photograph all sides of the offered batch label. Keep label text separate from seller explanations and unknowns. If the label does not name durian, do not infer suitability from “Grower” or the old schedule.

Frequently asked questions
What does NPK Grower mean for durian?
Grower is a marketing name, not a standard formula. As a historical comparator, the 2004 Peninsular DOA schedule prints 15:15:15 in each of the consecutive year 1, 2, 3 and 4 rows, then 12:12:17:2 in the year 5, 6, 7 and 8–25 rows. Grouping rows by formula is a derived summary, not a printed age band; annual totals and application counts differ. Use that formula pattern only if current orchard guidance agrees [source].
Is the 2004 DOA schedule current product advice?
No. It is a historically attributed schedule, not current universal advice or product approval.
How should I compare two offers?
Compare actual labels and dated written quotes, including net weight, delivery and the delivered total.
