Mostly, the propagation method followed in mango is grafting to produce true to type. Even though, this technique was commercial and also produce fruits in earlier. This technique needs skilled labours and more expenditure. So, the present investigation is focussed to develop a new methodology to produce mango plants through cuttings with less expenditure and true to type using IBA rooting hormone. Auxin is a plant growth hormone favours apical dominance and root growth promotion. IBA is a rooting hormone and induce the roots effectively within short duration. The present experiment was conducted in in Ramakrishna Mission Vivekananda Education and Research Institute, Faculty Centre for Agriculture Education and Research (FAR), Periyanaickenpalayam, Coimbatore. The research area lies between the coordinates of 11°08’16.5” N to 76°56’32.5” E. The Mango variety Banganapalli was used for this study. The concentrations of IBA (0, 1000, 3000 and 5000 ppm) were taken for the treatments with ten replications. The observation was taken at 14th, 20th days to record the bud sprout, length of the bud sprout and rooting percentage. The result was showed that bud sprout was recorded in all the treatments at 14thday after planting of cuttings. After 3rd week of planting most of the vegetative buds were died. Higher rate of survival and a greater number of bud sprout was observed in 3000 ppm of IBA after 4th week after planting. The number and length of the root was very minimal at 14th and 20th day. So, the study concluded that IBA concentration at 3000 ppm shows more survivability in mango cuttings and it may be used as rooting hormone, to induce the rooting and buds in the cuttings of mango.

Introduction Mango (Mangifera indica L.) is a tree belonging to Anacardiaceae family is known as “King of Indian Fruits” and is grown in almost all parts of India; due to its great utility and taste. Healthy as well as good quality plant material is the basic requirement and fundamental of successful fruit industry in any place. India occupies first position among mango growing countries of the world and produces 40.48% of the total world mango production. Major countries which receive the exported Indian mango are (2020-21): U Arab Emts, U K, Qatar, Oman, Kuwait. India is an important exporter of fresh mangoes to the world. India has exported 21,033.58 MT of fresh mangoes to the world for the worth of Rs. 271.84 crores/ 36.23 USD Millions during the year 2020-21. Andhra Pradesh, Uttar Pradesh, Karnataka, Bihar, Gujarat, and Tamil Nadu are the top mango- producing states in the country. With a share of 23.47 percent and the maximum productivity in mango production, Uttar Pradesh takes top place. In Tamil Nadu, the key types grown include Alphonso, Totapuri, Banganapalli, and Neelum (APEDA., 2021) [1] . Farmers and breeders are looking for easiest options with low cost techniques. To meet the mango production, there is a need of high-quality planting material. Most of researchers planned to produce planting material through cutting to avoid expenses. Rooting hormones have been identified as IBA. Asexually propagated fruit crops are easier to retain its purity (Bordolui et al., 2017) [2] . Exogenous application of IBA induces rooting in the stem cuttings. IBA enhances the root growth and also increases the numbers of roots. Auxin play role in rooting and occupies position of commercial application in cuttings. Application of 2000 ppm IBA increased the rooting percentage. The quality and density of roots were increased in the Wounded portion by IBA treatment (Kumar and Mitra, 1994) [3] . Cuttings propagation does not require technical labor. Hence, the present study focused to quantify the optimum concentration of IBA to induce rooting in mango cuttings and also to determine the Morpho-
