Land Prep & Planting
Chapter 06
Land preparation, step by step
- Clear and incorporate. Slash previous crop residues and weeds; where legume or green-manure crops preceded, incorporate at flowering for maximum N credit.
- Dig to 25–30 cm — by hoe, plough or tiller — and let weathered soil rest 1–2 weeks. Break clods; ginger rewards a fine, friable seedbed with even finger development.
- Form beds/ridges (Ch. 04 geometry) and open drainage channels first, not after planting. Bed-top should sit 15–25 cm above walkway level in rainy tracts.
- Base-dress and line. Full P (rock phosphate or SSP), ⅓–½ of N and ½ of K per your schedule (Ch. 09), plus 10–15 t/ha FYM/compost — worked into the bed top, not dumped in the planting line where seed touches fertilizer.
Planting mechanics
| Parameter | Recommendation | Why |
|---|---|---|
| Timing | Onset of reliable rains (e.g. April–May in SW monsoon India) or start of irrigation window | Emergence must ride the moist weeks; late planting shortens the bulking phase |
| Depth | 4–6 cm, bud up, covered with 2–3 cm soil | Deep planting delays emergence and buries the crown where rot starts first |
| Orientation | Buds upward / outward, cut face down where pieces are split | Even emergence; less water pooling on cut surfaces |
| Spacing | 20–25 cm × 20–25 cm on beds; 50–60 cm × 20–25 cm on ridges | Balance between canopy closure (weed control) and airflow (rot control) |
| Soil moisture | Plant into moist (not wet) soil; pre-irrigate if dry | Waterlogged planting = the classic first-week rot scenario |
Mulching — do it twice, at least
| Round | Timing | Material & rate | Functions |
|---|---|---|---|
| First | Immediately after planting | Paddy straw, dry leaves, coir pith, coconut frond sheaths — 10–15 t/ha (locally: "whatever the trees give") | Moisture, temperature buffer, splash-proofing, first weed suppression |
| Second | 40–60 DAP at earthing-up | 5–10 t/ha fresh material, topped into beds | Rebuilds the layer, feeds soil biology, suppresses the second weed flush |
In slash-mulch (jhum-type) systems the mulch is the fertility program: 5–10 t/ha of slashed vegetation forms a permanent litter blanket through which rhizomes grow and from which nutrients leach back with every rain.
Intercropping window: in wide systems, early-maturing legumes or vegetables can share the bed until ~90–120 DAP, when ginger's canopy closes. Keep intercrop fertilizer separate — don't rob the rhizome-initiation window to feed a cash catch-crop.
