Nursery Technique

 

Nursery technique:

          Raising propagules March, April or May months are suitable for raising nursery from seeds. Mature and healthy pods are chosen to collect theseeds; these are sown in raised nursery beds. It takes 10–15 days for the germination to complete. Pretreated seeds (10–12 kg) are sown per bed (10 m × 1 m) of sandy loam or loamy soil in April and covered with a thin layer of soil or hay. After one year, stumps can be prepared, which are planted in polybags in February to March, to be utilized after four to five months as stump-sprouted seedlings.

 

         Propagule rate and pretreatment About 1 kg  seeds are needed to raise seedlings for 1 hectare of plantation. Seeds show only about 50%–60% germination and about 40% plant survival. Seed treatment with GA3 (gibberellic acid)+BA (benzyladenine) @250 PPM (parts per million) helps in early and optimum germination. Alternatively, seeds can be soaked in cold water for 72 hours or in cow dung slurry for 72 hours[1].

 

          10 to 15 Kgs of pretreated seeds are sown per bed (12 x 1.2 mts) of sandy loam or loamy soil in April and covered with a thin layer of soil or hay. After one year, stumps can be prepared which are put in polybags in February to March, to be utilized after 4-5 months as stump sprouted seedlings[2].
