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.

    STUDIES ON PROPERTIES OF CONIFEROUS WOODS AVAILABLE IN THE MARKETS OF HIMACHAL PRADESH
    (UHF,NAUNI, 2016) CHAUHAN, KANICA; SHARMA, KULWANT RAI
    ABSTRACT The present research investigation entitled “Studies on properties of coniferous woods available in the markets of Himachal Pradesh” was carried out in the department of Forest Products, College of Forestry, Dr Y S Parmar university of Horticulture and Forestry, Nauni, Solan (HP) during the years 2013-2014, 2014-15 and 2015-16. Chemical analysis was carried out by employing TAPPI (Technical Association of Pulp and Paper Industry) standard methods. The mechanical strength properties were determined on UTN-10 (Universal Testing Machine) by standard procedures. The results revealed that moisture content (34.67%) and specific gravity (0.532) were found to be maximum in Cedrus deodara from Solan and Abies pindrow wood, from Sundernagar, respectively. The tracheid length (3.97 mm), tracheid diameter (50.01 µm) and ray width (32.05 µm) were recorded to be highest in Pinus roxburghii and ray length (0.680 µm) in Cedrus deodara wood collected from Chamba market. Maximum number of resin ducts (0.831/mm2) and fusiform rays (10.583/ mm2) were found in Pinus wallichiana from Sundernagar and Chamba markets, respectively. Whereas, uniseriate rays (44.97/mm2) were highest in Abies pindrow wood from Solan market. The wood samples of Pinus roxburghii collected from Solan market have shown maximum cold water solubility (7.18%), hot water solubility (8.88%), alcohol-benzene extractives (11.94%) and lignin content (30.68%). The holocellulose content (68.75%) was found to be highest in Pinus wallichiana wood from Solan market. The maximum tensile strength (0.057kN/mm2) and bending strength (0.003kN/mm2) were recorded in Pinus roxburghii from Solan. The compressive strength (0.110kN/mm2) and modulus of elasticity parallel to grain (0.031kN/mm2) were highest in Pinus wallichiana while, compressive strength (0.048kN/mm2) and modulus of elasticity perpendicular to grain (0.019kN/mm2) had largest values in Cedrus deodara from Solan. Modulus of Rupture (0.069kN/mm2) and Bending modulus of elasticity (0.070kN/mm2) have been found to be highest for Cedrus deodara samples from Solan and Sundernagar markets, respectively. Out of 336 combinations of simple correlation coefficients, 59 were found to be positive and significant while, 13 were found to be negative and significant. The value of regression coefficient R2 has been noticed to be highest for specific gravity for different mechanical-chemical (0.96) as well as mechanical-physical (0.99) parameters under study.
