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.

    ENVIRONMENTAL IMPACT ASSESSMENT OF NATIONAL HIGHWAY EXPANSIONS ON MOUNTAINOUS TERRAIN
    (NAUNI,UHF, 2020-12) BANYAL, SHELLY; AGGARWAL, R K
    ABSTRACT The present investigations entitled “Environmental Impact Assessment of National Highway Expansions on Mountainous Terrain” was conducted during the year 2018-2019 in the Department of Environmental Science Dr. Y S Parmar University of Horticulture and Forestry, Nauni-Solan, Himachal Pradesh. To study the impact of highway expansion activities on soil, water and air, study area was divided into 4 equal sites based on distance viz. Site1, Site 2, Site 3 and Site 4. The observations on different parameters at each site were recorded during pre-monsoon, monsoon and post-monsoon seasons and were replicated under randomized block design. In order to assess the floristic composition, each site was divided into three zones on the basis of habitat viz. moist zone, slope zone and top zone. The surface soil pH, EC and OC ranged from 7.06 to 7.54, 0.26 to 0.36 dsm-1and 0.40 to 1.29 % respectively. NPK content in the soil ranged from 262.59 to 328.12 kg ha-1, 25.84 to 51.34 kg ha-1 and 189.40 to 229.33 kg ha-1 respectively. The concentration of heavy metals Cd, Cr, Pb Cu, As, Ni and Hg in surface soil ranged from 0.012 to 0.028 mg kg-1, 0.016 to 0.047 mg kg-1, 0.20 to 2.74 mg kg-1, 0.17 to 0.42 mg kg-1, 0.014 to 0.030 mg kg-1, 0.011 to 0.032 mg kg-1and 0.43 to 0.85 mg kg-1 respectively. The total microbial count in the surface soil in the study area ranged from 31 x 106 CFU/g to 156 x 106 CFU/g. The surface water pH in the study area ranged from 7.01 to 7.53, EC from 0.20 to 0.30 dsm-1, TDS from 100.34 to 154.03 mg l-1 and turbidity ranged from 2.84 to 3.62 NTU. BOD and COD of surface water ranged from 1.92 to 2.72 mg l-1and 23.71 to 54.27 mg l-1respectively. The concentration of chloride and nitrate varied from 0.020 to 0.028 mg l-1and from 2.93 to 4.92 mg l-1respectively. The concentration of heavy metals Cd, Cr, Pb, Cu, Ni and As ranged from 0.005 to 0.016 mg l-1, 0.020 to 0.042 mg l-1, 0.20 to 0.028 mg l-1, 0.021 to 0.04 mg l-1, 0.011 to 0.030 mg l-1and from 0.021 to 0.045 mg l-1 respectively. The mercury was not detected in surface water. The air quality parameters like SO2, NO2, VOC’s and PM10 ranged from 6.24 to 7.53 μg m-3, 16.82 to 26.98 μg m-3, 2.75 to 6.37 μg m-3 and from 114.12 to 144.17 μg m-3 respectively. The soil carbon stock ranged from 8.29 Mg C ha-1 to 25.90 Mg C ha-1. The investigation further aimed to assess floristic composition and carbon loss of the study area. The flora of study area was found to be composed of 51plant species belongs to 33 families. The basal area among four sites was in the order of Majjhar>Dhali>Shunghal>Raghanv for trees where as for shrubs it fell in the order of Shunghal>Majjhar>Dhali>Raghanv. Vegetation indices viz., Shannon Weiner index, Species richness index and Simpson’s dominance index exhibited maximum value for tree and shrubs at Shunghal, Majjhar and Dhali respectively. The total of 13,967 tree species (including sapling, seedlings and poles) were felled during expansion of highway result in loss of carbon 2808.33 tonne ha-1. The flora and carbon sequestration potential can be restored by manual enrichment plantation.
