Field studies were conducted on vegetative propagation of a bamboo species Phyllostachys pubescens in the Department of Silviculture and Agroforestry, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (HP). The present investigation under study began with collecting root cuttings along with the rhizomes from the Regional Horticulture Research Centre, Bajaura located at kullu district of Himachal Pradesh. In the study, the rhizome cuttings of varying fragment length viz., 10 cm, 10-20 cm, 30 cm with at least one minimum bud. To prevent the fungal attack, cuttings were treated with solution of IBA @ 10ppm for 45 minutes before planting. Data collection, analysis and interpretation were conducted based on standard field and statistical procedures. The result reveals that regeneration success (%) of Phyllostachys pubescens when propagated in nursery condition at the time of sprouting, in the influence of growing media was observed maximum (43.69) in M2 followed by M3 (41.89), M1 (39.51) whereas; under the effect of burial depth was recorded highest (41.32) for burial depth of 10cm and the runner size of 20-30 cm length performed best with highest (48.43) average mean observed in RS3. It was concluded that for getting better quality planting stock of Phyllostachys pubescens the rhizome cuttings should be raised in sand-soil-FYM (2:1:1) growing media, with runner size of 20-30 cm and should be planted in 10 cm burial depth.ABSTRACT The present investigation entitled “Nursery performance of Phyllostachys pubescens in response to runner size and growing media” was conducted during the year 2020-21.
