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 DIFFERENT CLONES OF Populus deltoides (W. Bartram ex Marshall) FOR PHYSICOCHEMICAL PROPERTIES OF WOOD
    (UHF,NAUNI, 2018) AYLATE, ADANE SANBO; DUTT, BHUPENDER
    ABSTRACT The present research investigations entitled “Evaluation of different clones of Populus deltoides (W. Bartram ex Marsh.) for physico-chemical properties of wood” was carried out in the department of Forest Products, College of Forestry, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during the years 2016-17 and 2017-18. Chemical analysis was carried out by employing TAPPI (Technical Association of Pulp and Paper Industry) standard methods. Analysis of variance for growth and physical properties showed significant variations in all studied wood parameters except grain angle, texture and moisture content, whereas ash content showed non-significant variation among all chemical properties. The specific gravity and maximum moisture content (MMC %) were ranged from 0.287-0.343 and 227.76- 286.55 per cent, respectively. The maximum fiber length and fibre diameter was recorded in clone ‘S7C8’ whereas, maximum ray height, ray diameter, ray frequency, vessel diameter and vessel frequency were observed in clones ‘L-621/84’(0.276 mm), ‘PL-3’ (0.0148 mm), ‘G-48’ (46.22 rays per mm2), ‘L-200/ 86’ (0.057 mm) and ‘5503’ (88.02 vessels per mm2), respectively. The maximum cold water soluble extractives (3.68 %) and hot water soluble extractives (3.71 %) were noticed in clone ‘L-200/ 86’ whereas, maximum alcohol benzene extractives (4.30 %) and ash content (0.53 %) were revealed in clone ‘WSL-39’. The maximum holocellulose (76.87 %) was noticed in clones, ‘L-200/ 86’ and ‘WSL-22’. Significant and positive correlation coefficients were noticed between basal diameter vs height, holocellulose vs height, and holocellulose vs basal diameter. On the other hand, significant and negative correlation were revealed between lignin vs holocellulose content, wood per cent vs bark per cent, specific gravity vs maximum moisture content, lignin vs height and lignin vs basal diameter. For growth traits, high heritability was recorded in basal diameter (56.72 %) with genetic advance of 8.42 and genetic gain of 19.27 per cent. However, in anatomical properties, very high heritability was recorded in ray diameter, fibre length (94.53 %), ray height (93.60 %) and vessel frequency (73.98 %) while hot water was revealed high heritable (89.93 %) value in chemical properties followed by holocellulose (75.82 %). Positive genotypic and phenotypic correlations were found between height vs basal diameter, height vs ray diameter, basal diameter vs ray diameter, height vs holocellulose, basal diameter vs holocellulose, wood percent vs holocellulose and alcohol benzene vs lignin contents whereas, significant negative were observed between wood per cent vs bark per cent, specific gravity vs maximum moisture content and holocellulose content vs lignin content.
