PKM-1 Variety Overview
- Developed by: Horticultural College, Periyakulam (Tamil Nadu)
- Best for: Leaf and drumstick (pod) production
- Features:
- Early flowering: 90–100 days
- Pods: 45–75 cm
- High leaf yield
- Suitable for tropical/subtropical regions
Farming Method for PKM-1 Variety
1. Climate & Soil Requirements
- Climate: Warm, tropical; temperature 25–35°C
- Rainfall: 250–300 mm (avoid waterlogging)
- Soil: Sandy loam, well-drained; pH 6.2–7.0
- Avoid: Heavy clay or waterlogged soils
2. Land Preparation
- Plough the field 2–3 times for fine tilth.
- Prepare ridges and furrows or pits:
- Pit size: 45 × 45 × 45 cm
- Fill pits with:
- 10 kg FYM (farmyard manure)
- 250 g Neem cake
- 25 g Trichoderma for fungal protection
3. Seed Selection & Treatment
- Use pure PKM-1 seeds with >90% germination.
- Pre-treatment:
- Soak seeds in water for 8–12 hours before sowing for quick germination.
- Optionally treat with fungicide (Carbendazim 2 g/kg seeds).
4. Sowing Method
- Spacing:
- For pod production: 2.5 × 2.5 m (or 2 × 2 m)
- For leaf production (intensive): 0.45 × 0.45 m
- Sow 1 seed per pit at 2–3 cm depth.
- Germination starts in 8–10 days.
5. Irrigation
- First watering immediately after sowing.
- Maintain light irrigation every 7–10 days in dry areas.
- Avoid water stagnation.
6. Fertilizer Application
- At planting:
- 50 g N, 50 g P, 50 g K per plant (or 250:250:250 g/plant/year in split doses)
- Apply FYM or compost annually to maintain soil fertility.
- For leaves: Apply urea spray (2%) every 45 days for better growth.
7. Pruning & Training
- First pruning: 60–75 days after planting (plant height 60 cm)
- Cut at 45 cm above ground to encourage branching.
- Subsequent pruning: every 35–45 days for continuous leaf yield.
8. Pest & Disease Management
- Common pests: Hairy caterpillar, pod fly
- Control: Neem oil spray (3%) or Bacillus thuringiensis (Bt)
- Diseases: Root rot → avoid waterlogging + Trichoderma in soil.
9. Harvesting
- Leaves: 60 days after planting; then every 35–45 days
- Pods: Start after 6 months; full harvest in 8–10 months
- Yield:
- Leaves: 25–30 tons/ha/year
- Pods: 250–300 pods/tree/year
10. Economic Returns
- High profitability due to continuous leaf harvest and medicinal demand.
- Additional income from seeds for oil extraction.
