About PKM-2 Variety
- Developed by: TNAU (Tamil Nadu Agricultural University)
- Purpose: High-yielding drumstick pod variety (better than PKM-1 for pod length and weight)
- Features:
- Early bearing: Starts flowering at 90–100 days
- Pod length: 120–130 cm (longer than PKM-1)
- Pod weight: 150–200 g
- Yield: 400–500 pods per tree annually
- Oil content: 38–42% in seeds
- Suitable for pods + leaves farming
Farming Method for PKM-2
1. Climate & Soil
- Ideal Climate: Warm tropical/subtropical, 25–35°C
- Soil Type: Well-drained sandy loam; pH 6.0–7.5
- Avoid heavy clay and waterlogging
2. Land Preparation
- Plough 2–3 times to achieve fine tilth
- Layout:
- For pods: 2.5 × 2.5 m or 3 × 3 m spacing
- For leaves (intensive): 0.45 × 0.45 m
- Pit size: 45 × 45 × 45 cm
- Fill with:
- 10 kg FYM or compost
- 250 g Neem cake
- 25 g Trichoderma
3. Seed Selection & Treatment
- Use certified PKM-2 seeds (90% germination)
- Pre-soaking: 8–12 hrs in water
- Treat seeds with Carbendazim (2 g/kg) to prevent fungal infection
4. Sowing
- Depth: 2–3 cm
- Spacing:
- Pods: 2.5 × 2.5 m
- Leaves: 0.45 × 0.45 m
- Germination: 8–12 days
5. Irrigation
- First irrigation immediately after sowing
- Water every 3–4 days in dry conditions
- Avoid water stagnation
6. Fertilizer Application
- Basal dose per plant:
- 50 g Nitrogen, 50 g Phosphorus, 50 g Potassium
- Annual maintenance:
- 250:250:250 g NPK split into 2 doses
- For leaf crop: 2% Urea spray every 45 days
7. Pruning
- First pruning: 60 days after planting (when plant reaches 60 cm)
- Cut at 45 cm height to promote branching
- Regular pruning: Every 35–45 days for leaf farming
8. Pest & Disease Management
- Common pests: Hairy caterpillar, Pod fly
- Control with Neem oil (3%) or Bt spray
- Root rot: Prevent by using Trichoderma and good drainage
9. Harvesting
- Leaves: 60 days after sowing, then every 35–45 days
- Pods: Starts at 6–8 months; peak yield in 10–12 months
- Yield:
- Pods: 400–500 per tree/year
- Leaves: 25–30 tons/ha/year
10. Economics
- Higher pod yield compared to PKM-1
- Continuous income from pods, leaves, seeds
