Abstract
Comparative performance of Simarouba glauca seedlings grown in poly pot, nursery beds and root trainer was investigated with an aim to select suitable substrata for seed germination and container for quality seedlings production. Seed germination percentage, imbibition period and energy period found higher in raised nursery bed followed by root trainer and flat bed. Among substrates, raised bed method has significant higher scope in ensuring seed germination and seedling availability for commercial nursery. Morphological parameters of seedlings viz., shoot length, root length, collar diameter, fresh weight, dry matter production and number of leaves were recorded maximum in T1 and T3 treatments. Vigor index and quality index were also significantly higher in T1 and T3 treatments. T3 treatment revealed best performance in respect to germination and other growth parameters. However, T1 treatment was found suitable in the nursery for quality seedling production of Simarouba glauca.
