            | Nursery    Technique | 
            Fresh seeds sown in pots, 3 feet each.    Germination starts within one week and planted out next year. Roots establish    first and shoot increases later. They can also be sown in seed beds 15 cm x    3.5 cm apart, sparingly watered and pricked out at 15 x 15 cm when two months    old and planted out with ball of earth next year. Planting of seedlings with    initial germinating vigour(50% culling) will perform better. For raising    taller plants 30 x 45, 35 x 50 HDP bags, proper mixture 1: 1: 1 is absolutely    necessary, especially in drip irrigation it gives 8 feet in only 4 months. |
