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.

The study revealed significant variation between physical, anatomical, chemical and mechanical characteristics of toon wood from different market location of Himachal Pradesh. The samples of the toon wood were noticed with fine texture and wood colour was noticed as moderate reddish brown 166 [B] and moderate orange 166 [D] in most of the samples. The maximum specific gravity was noticed in Soutta (0.534) and minimum in Badibhu (0.487). The moisture content of toon wood ranged from 21.00 to 27.09 per cent. In case of anatomical parameters, the longest fibre length was recorded in Shahpur (1.047 mm) and the shortest in Shambhuwala (0.862 mm) with fibre width ranged from 0.019 to 0.020 mm. The maximum vessel diameter observed in Kheri (0.165 mm) and minimum in Sarahan (0.135 mm). The vessel frequency ranged from 4.317 mm2 to 6.792 /mm2. The longest ray length was recorded in Shambhuwala (0.417mm) whereas, the shortest in Rajgarh (0.264 mm) while, the ray width was found to be widest in Shambhuwala (0.085 mm) and narrowest in Rajgarh (0.063 mm). The ray frequency ranged from 9.587 mm2 to 13.328 mm2. Among the different chemical parameters, the percentage of cold water, hot water, alcohol benzene and NaOH soluble extractives were found to be highest in Sarahan (5.09 %), Bhalja (8.65 %), Bhalja (8.90 %) and Kandaror (8.95 %) respectively. The maximum percentage of holocellulose and lignin content were recorded in Bhalja (72.34 %) and Kheri (24.65 %), respectively. Among different mechanical properties, the maximum tensile and bending strength was recorded in Galore (0.120 kN/mm2) and Shambhuwala (0.014 kN/mm2. The maximum compressive strength parallel and perpendicular to grain was noticed in Tectona grandis (0.067kN/mm2) and Kheri (0.058 kN/mm2), respectively. The highest modulus of elasticity parallel to grain was observed in Soutta (1.282 kN/mm2). The maximum tensile and bending modulus of elasticity was observed in Sarahan (2.543 kN/mm2) and Kandaror (37.597 kN/mm2), respectively. The bending modulus of rupture was observed to be maximum in Shambhuwala (0.268 kN/mm2) and minimum in Kheri (0.227 kN/mm2). The maximum elongation with tension and bending was found in Shambhuwala (6.79 %) and Soutta (3.72 %), respectively. Highly significant positive correlations were found between fibre length and ray frequency (0.418) and vessel diameter (0.463) at 1 per cent level of significance. The specific gravity was found to be positively significant with holocellulose (0.374) at 1 percent level of significance and with Alcohol benzene soluble extractives (0.348) at 5 per cent level of significance. In case of simple correlation in mechanical properties, the highest positive correlation was noticed between Bending strength and Modulus of rupture in bending (0.963).

    (UHF,NAUNI, 2018-04) DHIMAN, BANDANA; SHARMA, KULWANT RAI
    Abstract The present research entitled on “Physico-chemical evaluation of wood of toon (Toona ciliata M. Roem.) provenances from Himachal Pradesh” 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 2014-17. The study revealed significant variation between physical, anatomical and chemical characteristics of wood from different toon provenances. Among different physical parameters, the highest bark, wood, sapwood and heartwood per cent (on diameter basis) was recorded in Bhota (14.47 %), Nahan (89.03 %), Nurpur (22.07 %) and Nahan (69.87 %) respectively and minimum in Nahan (10.97 %), Bhota (85.53 %), Chambaghat (17.98 %) and Dehra (64.27 %) respectively. Bark, wood, sapwood and heartwood per cent (on basal area basis) was recorded maximum in Bhota (26.82 %), Baddi (79.75 %), Nurpur (36.33 %) and Nauni (49.58 %), respectively. The minimum was in Baddi (20.25 %), Bhota (73.18 %), Arki (27.79 %) and Nurpur (39.09 %) respectively. In case of altitudinal variations, sapwood and heartwood percentage have been found to be significant in both diameter and basal area basis, while rest were noticed as nonsignificant. The highest sapwood moisture content (mc) and maximum moisture content (mmc) was observed in Rehan (57.96 %) and Ghanahati (179.02 %), whereas minimum was recorded in Nahan (42.34 %) and Una ((148.01 %). The heartwood mc and mmc was observed highest (51.59 %) and (168.38 %) both in Rehan, whereas minimum was found in Arki (36.16 %) and Sujanpur (130.88 %) respectively. The highest sapwood and heartwood specific gravity (0.506) and (0.519) for both was found in Ghumarwin and minimum (0.458) and (0.490) in Mandi and Rajgarh respectively. Altitudinal variations for sapwood specific gravity have revealed non-significant variations and heartwood specific gravity showed significant variation. The longest fibre length (1.097 mm) was recorded in Baddi, whereas shortest (0.785 mm) in Ghanahati. Widest fibre diameter (0.022 mm) was recorded in Sugh and lowest value (0.020 mm) was noticed in all remaining provenances. The vessel diameter was found to be highest (0.163 mm) in Sugh and lowest (0.111 mm) value was recorded in Chambaghat. The maximum vessel frequency was found in Bhota (6.253 /mm2) and minimum (4.095 /mm2) in Dehra. The largest ray height was recorded maximum (0.417 mm) in Renuka and smallest in Palampur (0.273 mm). The ray width was observed to be highest in Una (0.076 mm) and lowest (0.058 mm) in Sujanpur In case of ray frequency, maximum value was recorded in Bhota (12.762 /mm2) and minimum in Chambaghat (9.523 /mm2). For all anatomical parameters, altitudinal variations showed significant results. Among the different chemical properties studied, the maximum cold water (6.38 %), hot water (9.80 %), alcohol benzene (8.74 %), and NaOH extractives (9.06 %) were found in Mandi, Sarahan, Rajgarh and Shahpur respectively. Whereas minimum cold water (3.90 %), hot water (7.25 %) alcohol- benzene (6.59 %) and NaOH (6.08 %) extractives were observed to be minimum in Baddi, Palampur, Baddi and Sujanpur respectively The maximum holocellulose (73.82 %) and lignin (25.95 %) contents were recorded in Sarahan and Sundernagar respectively while, minimum holocellulose (67.05 %) and lignin (21.03 %) was noticed in Renuka and Ghumarwin. In case of altitudinal variations, hot water, alcohol benzene and NaOH soluble extractives were recorded to be significant, however cold water soluble extractives, holocellulose and lignin content were found to be non-significant. The values for simple correlation coefficients between physical characterstic of tree components with anatomical features and chemical characteristics were also recorded and analyased. The results revealed that heartwood specific gravity was positively correlated with sapwood specific gravity (0.466) and bark content (%) has highly negative and significant correlation with heartwood (-0.770). Fibre length was positively correlated with fibre width (0.250), fibre width positively correlated ray height (0.328), vessel frequency negatively correlated with ray width (-0.256) and ray width positively correlated with ray height (0.282).

    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.
