The hardwood stem cuttings of Mulberry basal portions were treated with 0, 150, 250, 500, and 750 ppm solutions of IBA for 24hrs by slow dip method. The mulberry cuttings have rooted on raised beds under the open field conditions. In all the treatments, Number of sprouted cuttings, average length of sprouts (cm) and diameter of sprouts (mm) were higher in T 2 treatment (IBA 150 mg l -1 ) and a live cutting (%), no. of roots/cutting, length of roots/cutting (cm) was higher in T 5 treatment (IBA 750 mgl -1 ). Key words : Mulberry, Hardwood stem cuttings, IBA concentrations, and Rooted cuttings Introduction Moras alba is a deciduous fruit tree of the Moraceae family. It has been cultivated for thousands of years. It is widespread in the tropical and subtropical re- gions of Africa, Europetropical America and Asia (Ozgen et al., 2009). The leaves of Moras alba using in the cultivation of the silkworm India and China. The productions of true to type plants is possible only by the method of Asexual propagation (Haq, 1992). Propagation of Mulberry with different methods such as cutting, budding and grafting (Guo et al., 2009). In this mulberry propagated by the hardwood cuttings is the simplest, low cost and fastest method (Rao and Khan, 1963). It has been observed that cut- tings are one of the methods adopted for asexual propagation such as rooting and cuttings play an important role in isolating certain fruit species and rootstocks. The diameter of the stem cuttings influ- enced the successful rooting of mulberry, some chemicals were used to increase the successful rate of cuttings propagation. The most common method is to use exogenous growth substances for rooting in cuttings (Polat and Kamilolu, 2007). In cuttings, the formation of roots promoted by the IBAtreatment. Formation of roots in stem cuttings as affected by plant growth regulators, planting time of cutting, age of stock plant, method of planting and shoot position. Keeping this object in view, Current work has been undertaken to investigate the effect of IBA on the rooting ability of Morus alba stem cuttings in open condition. Materials and Methods The current study was investigated in the research field of the Dept of Horticulture, Lovely Professional University, Punjab, India in a randomized block design (RBD). The experimental area consists sub- tropical climate with four distinct seasons: in Dec- Feb extreme winter, in March – May cold spring, in June - August light summer and September- No- vember autumn. The research field is received snow and rains from December to March. The stem cut- DOI No.: http://doi.org/10.53550/EEC.2022.v28i04.023
