Clonal Propagation of Aegle marmelos through IBA Treatment for Sustainable Nutritional and Medicinal Supply for the Poor People of Agrarian Bangladesh

The study was carried out at the Agriculture research field of Patuakhali Science and Technology University (PSTU) from March to October, 2017 to explore rooting performance of Aegle marmelos (Bael) through clonal propagation by stem cutting under 3 different doses of IBA (Indole Buetaric Acid) and planted in the perforated plastic tray filled with coarse sand and gravel placed in the non-mist propagator. The experiment was laid out following a Randomized Complete Block Design (RCBD) with 4 treatments and 4 replications (blocks). The treatments were T0= control, T1 = 0.2% IBA, T2 = 0.4% IBA, T3 = 0.8% IBA. The rooting ability of cuttings was significantly influenced by the application of IBA. The highest rooting percentage (60%) was recorded in A. marmelos both with 0.2% and 0.4% IBA followed by 0.8% IBA (40%). Longest root (3 cm) was recorded with 0.4% IBA followed by 0.2% IBA (1.2 cm). The maximum root number (2.25) and root diameter (2 mm) obtained from cuttings treated with 0.8% IBA followed by 0.4% IBA (2 and 1.9 mm respectively). Survival percentage of the cutlings (the rooted cuttings) significantly enhanced by exogenous rooting hormone (IBA) application. The highest survival percentage (73.5%) was observed for the cuttings treated with 0.4% IBA followed by 0.8% IBA (68.5%). Findings of the present study reveal that the plant species is highly amenable for clonal propagation by stem cuttings using low-cost non-mist propagator. Considering rooting percentage, root number and and root length, 0.4% IBA treatment may be recommended for mass production of quality planting stocks. Farmers and nursery owners can be trained up regarding this low cost non-mist propagation system of Aegle marmelos for cultivation of the species in homestead agroforestry or in fruit orchards for sustainable nutritional and medicinal supply for the poor people of agrarian Bangladesh.
