Abstract:
Investigation on the growth parameters of mulberry saplings (Morus sp.) grown under aeroponic system and nursery condition were assessed at 15, 30, 45 and 60 days after transplanting. The plants grown under aeroponic system were recorded maximum for longest root length, number of primary roots, root biomass, longest shoot length and number of shoots. Among treatments, T₃ (three buds per cutting) recorded maximum for all growth parameters studied followed by T₂ (two buds per cutting) and T₁ (one bud per cutting). The interaction effect between propagation systems and number of buds per cutting showed significant results. S₁T₃ (Three budded cuttings under aeroponic system) recorded maximum for growth parameters viz., number of primary roots (46.80), longest root length (26.90cm), root biomass (1.17g), number of shoots (6.63), longest shoot length (24.55cm) whereas least was recorded by S₂T₁(One budded cuttings under nursery) i.e., 20.00, 14.60cm, 0.38 g, 1.06 and 15.47 cm respectively at 60 DAT. From these results it can be concluded that, the aeroponic system could be effectively used for the production of V-1 mulberry saplings.
