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.

    VARIATION IN PHYSICO-MECHANICAL PROPERTIES OF MARKET SAMPLES OF Acacia nilotica (L.) Willd ex DELILE WOOD
    (UHF,NAUNI, 2017-09) THAKUR, PRIYADARSHINI; SHARMA, KULWANT RAI
    ABSTRACT The present research investigation entitled “Variation in physico-mechanical properties of market samples of Acacia nilotica (L.) Willd ex Delile wood” 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 2015-16 and 2016-17.The identification and authentication of the samples were carried out. The maximum vessel diameter of (0.158mm) was recorded in samples from Parwanoo-K whereas minimum value was recorded in Chowkiwala (0.127mm). In the cross sectional studies mostly vasicentric and occasionally aliform type of parenchymatous tissues has been observed. Medium sized and thicker fibers were observed in the radial sections of wood, whereas gum ducts were present in most of the longitudinal sections of wood. Fine texture and light to moderate reddish brown colour has been observed in most of the samples collected from different locations. The physical properties were estimated using several parameters under consideration. The highest moisture content (28.033%) noticed in Parwanoo-1 location, while the lowest moisture content in Datowal (8.559%). The MMC (%) was found to be highest (107.719%) in Nalagarh-2 location and lowest (59.255%) in Baddi. The maximum specific gravity (0.802) was recorded in Baddi and minimum (0.585) from Nalagarh- 2.The maximum fibre length (1.320 mm) was recorded in Jhadhmajri and minimum (0.668 mm) from Barotiwala. The maximum fiber diameter of (0.0248 mm) was recorded in Baddi and minimum value of (0.0219 mm) in samples from Jhadhmajri. The mechanical strength properties were determined on UTN-10 (Universal Testing Machine) by following standard procedures. The tensile strength and elongation in tension was observed maximum in samples collected from Chowkiwala and Parwanoo-2, respectively. The maximum compressive strength perpendicular to grain was recorded in Parwanoo-1 market samples. The wood samples collected from Baddi market have shown maximum compressive strength parallel to grain, modulus of elasticity parallel to grain, bending modulus of elasticity and elongation in bending The maximum bending strength and bending modulus of rupture was observed in teak (control) followed by samples from Baddi market whereas, the highest modulus of elasticity in tension was recorded in teak (control) followed by Barotiwala market samples. Out of total 105 combinations, of simple correlation coefficients obtained between physical and mechanical parameters 13 were found to be significant and positive whereas, 7 were reported as negatively correlated and significant. R2 value for specific gravity has been noticed to be highest due to different mechanical-physical parameters under study.

    VARIATION IN PHYSICO-MECHANICAL PROPERTIES OF MARKET SAMPLES OF SHISHAM WOOD (Dalbergia sissoo Roxb. ex DC.)
    (UHF,NAUNI, 2017) SUNNY, PAVIN PRAIZE; DUTT, BHUPENDER
    Dr. Bhupender Dutt ABSTRACT The present research entitled Variation in physico-mechanical properties of market samples of Shisham wood (Dalbergia sissoo Roxb. ex DC.) 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 2015-16 and 2016-17. The study revealed significant variation between physical and mechanical properties of wood of shisham woods collected from different market sites. The maximum moisture content of (20.170%) was observed in the wood samples of Nalagarh site, highest maximum moisture content (68.326%) found in the samples from Nalagarh site. Highest specific gravity of (0.644) in Dattowal site and lowest in Nalagarh site i.e., 0.7480. Maximum vessel diameter (0.126 mm), fibre diameter (0.020 mm) and fibre length (1.66 mm) was found in the wood samples from Ghumarwin, Dattowal and Ghumarwin site respectively. In case of mechanical properties of wood samples of Shisham, significant variation was observed for all the studied parameters. The maximum bending strength was recorded in Baroh and Sundernagar site (0.006 kN/mm2) and maximum tensile strength (0.094 kN/mm2) was noticed in the wood samples from Baroh site. The maximum compressive strength parallel to grain (0.069 kN/mm2) was observed in Kangu site and maximum compressive strength perpendicular to grain (0.038 kN/mm2) was found in of Baroh site. The maximum modulus of elasticity parallel to grain (0.231 kN/mm2) was recorded in Ghumarwin and maximum modulus of elasticity perpendicular to grain (1.653 kN/mm2) was noticed in wood samples of Galore site. The greater modulus of elasticity due to tension and bending are in the wood samples of the sites Baroh (2.876 kN/mm2) and Kangu (10.369 kN/mm2) respectively. The maximum bending modulus of rupture was observed in the wood samples from the sites of Sundernagar (0.116 kN/mm2) and for Teak was found to be 0.323 kN/mm2. The maximum elongation for shisham wood samples for bending was found in Nalagarh site (0.039 mm) and for tension in the site of Sarahan (0.033 mm). Majority the mechanical properties of Shisham wood were compared with standard Teak wood samples and found that the wood samples of Shisham were superior in some mechanical properties.
