Okra
Technical data
| pH range | 6.0–6.8 (typical for okra) |
|---|---|
| In-row spacing | 23–30 cm |
| Row spacing | 90–120 cm |
| Days to first harvest | 55–70 |
| Harvest frequency | Pick every 1–2 days — pods get tough fast and the plant slows if you miss picks. |
| Expected yield | Varies with variety and season; pick young pods for best market quality. |
| Key nutrients | Potassium and calcium for pods; steady but modest nitrogen. |
| Common deficiencies | Calcium (poor pod quality), boron (poor fruit set). |
| Chemical-finder crop slug | okra |
| Data confidence | medium |
| Review status | needs review |

Nutrient targets
No NT-specific fertigation target sheet found — use the Clemson side-dress guidance above and your own sap/soil tests. Flagged for review.
Growth stages
| Stage | Timing | Notes |
|---|---|---|
| Establishment | 0–3 weeks | Germination and early leaves; keep moist, go easy on nitrogen. |
| Vegetative | 3–6 weeks | Plants bulk up; first side-dress. |
| Flowering | 6–8 weeks | Calcium/boron matter for fruit set. |
| Podding/harvest | 8+ weeks | Pick every 1–2 days; second side-dress. |
Spacing and plant numbers
Plant spacing: 23–30 cm Row spacing: 90–120 cm
At 27 cm spacing that is about 370 plants per 100 m row.

Task calendar Sample — no tasks are created until you confirm a trial plan
| When | Task | Notes |
|---|---|---|
| 7 days before planting | Bed preparation | Raised, free-draining beds with organic matter. |
| 3 days before planting | Irrigation setup | Lay drip lines; check even flow. |
| Planting day | Planting | Sow/transplant at 23–30 cm spacing. |
| 7 days after planting | First fertigation | Light balanced feed; avoid heavy nitrogen. |
| 14 days after planting | Scouting | Aphids/mites on new growth. |
| 21 days after planting | Side-dress (calcium nitrate) | Clemson: ~3–6 lb 15.5-0-0 / 1000 sq ft. |
| 28 days after planting | Pest monitoring | Weekly from here. |
| 42 days after planting | Second side-dress | As podding begins. |
| 60 days after planting | First harvest estimate | Pods at 5–8 cm; then pick every 1–2 days. |
Labour notes
Harvest labour is the big one — daily picking during the season. Budget for it before scaling up.
Chemical options (APVMA only)
Live from the APVMA PubCRIS finder — registration, WHP, rate and the source badge come from the finder API at view time, never stored here. Always confirm the current APVMA label before use. Pests/diseases without a finder filter (and biosecurity diseases) are not shown here — check the label or a permit directly.
