Dr. Y. S. Parmar University of Horticulture & Forestry, Solan

Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Solan, was established on 1st December, 1985 with the objective to promote education, research and extension education in the fields of Horticulture, Forestry and allied disciplines. Late Dr. Yashwant Singh Parmar, the first Chief Minister and the architect of Himachal Pradesh perceived the importance of Horticulture and Forestry to develop and improve the State economy which led to the establishment of this University. Its history lies in erstwhile Himachal Agricultural College, Solan, established in 1962 and affiliated to the Panjab University. It became one of the campuses of Agriculture Complex of Himachal Pradesh University on its formation in 1970. Consequent upon the establishment of Himachal Pradesh Krishi Vishvavidyalaya in 1978, this campus became its Horticulture Complex and finally in 1985, assumed the status of a State University, being the only University in the country engaged exclusively in teaching, research and extension in Horticulture and Forestry. The University is located at Nauni in Solan District of Himachal Pradesh, 13 km from Solan on Solan-Rajgarh Road, at an elevation of 1300 metres above mean sea level. Solan town is situated on national highway (NH-22) and is well connected by train and bus services. The University has four constituent colleges, out of which, two are located at the main campus Nauni, one for horticulture and the other for forestry, having 9 and 7 departments, respectively. The third College i.e., College of Horticulture & Forestry is located at Neri in Hamirpur District on Nadaun-Hamirpur state highway, about 6 Km from Hamirpur town and is well connected with bus service. The college offers three Undergraduate Degree Programmes i.e. BSc (Hons.) Horticulture, BSc (Hons.) Forestry and B. Tech. Biotechnology and MSc degree programme in a few subjects. The fourth college i.e. College of Horticulture and Forestry, Thunag (Mandi) is located at Thunag District Mandi. This college offer BSc (Hons.) Horticulture and BSc (Hons.) Forestry degree programme. In addition, there are five Regional Research Stations, 12 Satellite Stations and five Krishi Vigyan Kendras (KVKs) situated in different zones of the State.

    “Evaluation of Willow (Salixspecies) Clones for physical and Mechanical Properties of Wood”
    (UHF,NAUNI, 2014) HEENA; SHARMA, K.R.
    ABSTRACT The present research entitled “Evaluation of Willow (Salix species) Clones for Physical and Mechanical Properties of Wood” was carried out in the Laboratory and Wood Workshop in the Department of Forest Products, College of Forestry, Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2012-13 and 2013-14. The study revealed significant variation between physical and mechanical properties of wood of Willow clones growing at two sites. Among different physical characteristics Salix babylonica registered maximum height (21.06 m) and diameter (17.50 cm). The height and diameter value obtained for Poplar was 12.40 m and 13.17 cm. Maximum bark and wood per cent was noticed in clones Salix tetrasperma(24.98%) and Kashmiri-6 (95.58%), respectively. In Poplar bark and wood per cent was observed as 7.10% and 92.90%, respectively. The maximum moisture content of 108.00% was found in clone Salix babylonica, specific gravity of 0.6120 in clone V-99 and fibre length of 1.14 mm in clone NZ-1002. The values for moisture content, specific gravity and fibre length recorded for poplar was 91.45%, 0.5570 and 1.28 mm, respectively. Among mechanical properties of wood of willow clones, significant variation was observed for all the studied parameters. The maximum tensile strength was recorded in clone J-795(0.073 kN/mm 2 ) and maximum bending strength (0.006 kN/mm 2 ) was noticed in clones SE-63-016 and V-99. The tensile and bending strength recorded in Teak wood samples was 0.089 kN/mm 2 and 0.031 kN/mm 2 . The maximum compressive strength parallel to grain (0.044 kN/mm 2 ) was observed in Salix babylonicaand maximum compressive strength perpendicular to grain (0.007 kN/mm 2 ) was found in clone MB-368. The compressive strength parallel to grain and perpendicular to grain was observed as 0.074 kN/mm 2 and 0.019 kN/mm 2 , respectively in standard Teak wood samples. The maximum modulus of elasticity parallel to grain (2888.89 kN/mm 2 ) was recorded in clone PN-227 and maximum modulus of elasticity perpendicular to grain (800.00 kN/mm 2 ) was noticed in clone J-795.in standard Teak wood samples values for modulus of elasticity parallel and perpendicular to grain was 8097.22 kN/mm 2 and 1475 kN/mm 2 , respectively. All the mechanical properties of Willow clones were compared with Standard Teak wood samples and found that the wood samples of Teak are superior to all the Willow clones.
