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.

    ASSESSMENT OF TOXIC METAL STATUS IN CONTAMINATED INDUSTRIAL SITES AND THEIR BIOREMEDIATION IN HIMACHAL PRADESH
    (UHF,NAUNI, 2023-02) SHIVANI; AGGARWAL, R K
    ABSTRACT The present study entitled “Assessment of toxic metal status in contaminated industrial sites and their bioremediation in Himachal Pradesh” was conducted during 2021-2022 in the Department of Environmental Science, Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan H.P. The study aims at determining the status of toxic metals in the soil of industrial sites and isolation of potential fungal strains to test their bioremediation potential at different concentrations of toxic metals. Seven toxic metals As, Cd, Cr, Cu, Ni, Pb, and Zn were identified from the soil samples of steel, dye and paper industries at three distances; within the industry, 50 m from the industry and 100 m from the industry in Kala-Amb (Sirmour), Baddi (Solan) and Una (Una). Four toxic metals Cu, Ni, Pb and Zn were found in high concentrations in soil samples from the industries. Five strains of fungi were successfully isolated from soil samples and identified by NCMR, Pune as Penicillium commune, Aspergillus flavus, Trichoderma asperellum, Pencillium camemberti and Aspergillus niger. Six fungal consortia were obtained namely; Penicillium commune × Aspergillus flavus, Penicillium camemberti × Penicillium commune, Aspergillus flavus × Penicillium camemberti, Penicillium camemberti × Aspergillus niger, Trichoderma asperellum × Penicillium camemberti and Aspergillus flavus × Aspergillus niger. The bioremediation potential of identified fungi and consortia was tested in-vitro at 0ppm, 10ppm, 20ppm, 30 ppm and 40 ppm concentrations of Cu, Ni, Pb and Zn by studying parameters viz. radial growth rate, per cent growth inhibition, tolerance index, mycelium dry weight and biosorption of toxic metals by fungi. The maximum mean radial growth rate of 0.692 mmh-1 was exhibited by T. Asperellum for Cu; for Ni and Pb (0.692 mmh-1) by T. asperellum and P. camemberti; and for Zn (0.695 mmh-1) by T. asperellum. Maximum biosorption of 144 mgg-1 and 142 mgg-1 was exhibited by T. Asperellum for Cu and Zn, 148 mgg-1 and 135 mgg- 1 by P. Camemberti for Ni and Pb respectively. The maximum removal efficiency was exhibited by T. asperellum, for Cu (16.7 %) Ni (17.3 %), Pb (17.0 %) and Zn (19.4 %). Maximum biosorption of Cu (135 mgg- 1), Ni (147 mgg-1), Pb (151 mgg-1) and Zn (150 mgg-1) was exhibited by consortia Trichoderma asperellum × Penicillium camemberti. The consortia Trichoderma asperellum × Penicillium camemberti showed maximum removal efficiency for Cu (19.4 %), Ni (15.9 %), Pb (17.3 %) and Zn (15.9 %). Fungi T. Asperellum, P. Camemberti and consortia Trichoderma asperellum × Penicillium camemberti exhibited high radial growth rates, minimum per cent growth inhibition, high tolerance index and high biosorption capacity at all concentrations of Cu, Ni, Pb and Zn. From this study, it can be concluded that fungi T. asperellum, P. camemberti and consortia Trichoderma asperellum × Penicillium camemberti have high remediation potential for Cu, Ni, Pb and Zn. The present study also widens the scope for studying the bioremediation potential of fungal consortia for toxic metals in the futur
