Abstract:
Leucaena leucocephala (Lam.) de Wit and Gliricidia sepium (Jacq.) Walp seedlings were grown in polybag, nursery bed and root trainers and investigated with an aim to select suitable containers for raising quality seedlings in large scale plantation programs. Seed germination and seedling growth were assessed for shoot length, root length, collar diameter, fresh weight, dry matter production, leaf number and number of nodules of the seedlings. Vigor index, quality index, imbibition period, energy period and root shoot ratio were also calculated for each treatment. Germination percentage was found better in nursery bed. Seedlings raised in polybags of 23 x 15 cm size revealed best performance in respect to germination and other growth parameters. Root-shoot ratio of L. leucocephala was higher in 12 x 15 cm polybag and the same for G. sepium was higher in root trainer in comparison to other treatments. Polybag size of 23 x 15 cm was found suitable in the nursery for quality seedling production of Leucaena leucocephala and Gliricidia sepium.
