Efficacy of different levels of IBA and NAA on rooting of Phalsa (Grewia asiatica L.) cuttings

Abstract

Vegetative propagation of Phalsa (Grewia asiatica L.) through cutting is the most convenient and the cheapest method to obtain true to the type fully developed plants in considerably lesser time. The effect of various concentrations of IBA and NAA on the rooting and shooting of hardwood cutting of Phalsa was assessed in an experiment conducted at the AICRP on tropical fruit crops, Mondouri, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia (West Bengal), India. The experiment was laid out in Completely Randomized Design (CRD) with three replications. Maximum rooting (70.55%), root number (40.85) and root length (27.47 cm) is observed that hard wood cutting treated with IBA 200 ppm by dipping in prepared solution for 24 hours. Field survival of the plants develop through hard wood cuttings treated with IBA 200 ppm (37.82%) followed by NAA 200 ppm (30.47%) was found superior over all the treatments.
