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.

    EFFECT OF COPPER TOXICITY ON GROWTH PARAMETERS OF Populus deltoides (W. BARTRAM EX.MARSHALL) AND ITS BIOREMEDIATION BY ENTOMOPATHOGENIC FUNGI
    (2015) GAYATRI, DHUMAL; THAKUR, MEENA
    ABSTRACT The present investigation entitled “Effect of copper toxicity on growth parameters of Populus deltoides (W. Bartram ex. Marshall) and its bioremediation by entomopathogenic fungi” was carried under laboratory conditions in the Department of Environmental Science, College of Forestry, and Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan during HP 2013-2014.The studies were completed with two experiments; experiment one comprised of eleven treatments viz., T1 (Nocopper), T2 (100 ppm Cu), T3 (200 ppm Cu), T4 (100 ppm Cu + M. anisopliae, 1x105 condia/ml), T5 (100 ppm Cu + M. anisopliae, 1x106 condia/ml), T6 (200 ppm Cu + M. anisopliae, 1x105 condia/ml), T7 (200 ppm Cu + M. anisopliae, 1x106 condia/ml), T8 (100 ppm Cu + B. bassiana, 1 x 105 condia/ml), T9 (100 ppm Cu + B. bassiana, 1x106 condia/ml), T10 (200 ppm Cu + B. bassiana (1x105 condia/ml), T11 (200 ppm Cu + B. bassiana ,1x106 condia/ml).whereas, experiment two included seven treatments having only higher doses of entomopathogenic fungi. Highest (53) and lowest (33) numbers of leaves per plant of P. deltoides were recorded at treatment T5 and T1 respectively, whereas, leaf area was maximum (0.16 m2) and minimum (0.08 m2) at treatments T9 and T1, respectively. Maximum plant height of 1.76 m was observed in treatment T5. The biomass of different plant parts of P. deltoides viz., roots, stem and leaves was statistically minimum at T1, the root and stem biomass showed increase at 100 ppm copper along with entomopathogenic fungi, leaf biomass was statistically similar at T2, T8 and T9 treatments. Highest chlorophyll content was recorded at T9 and lowest was at T10 and T3. There was an increase in ascorbic acid with concentration of copper. The treatment combinations of 100 ppm copper with entomopathogenic fungi recorded higher ascorbic acid content than respective control, whereas, there was decrease in ascorbic acid content in treatments with 200 ppm copper combination with entomopathogenic fungi. As compared to control (T1) there was increase in total sugar content of P. deltiodes but there was no significant difference between the respective control and their treatment combination with entomopathogenic fungi. There was increase in total phenol content of plants with increase in copper concentration to 200 ppm, highest phenol content was at T3. Distribution of copper content in different parts of P. deltoides was in the order of root> stem> leaves. The highest uptake of copper in roots, stem and leaves was 0.32, 0.57 and 0.18 mg/plant, respectively. Entomopathogenic fungi reduced the copper levels in soil to some extent. Highest percent reduction (21.89 %) was at T11, Highest percent reduction (35.09) of 100 ppm copper was recorded with M. anisopliae, 1x106 condia/ml, whereas, B. bassiana (1x106 condia/ml) recorded highest percent reduction (34.05) of 200 ppm copper. There was decrease in protein content of white grub (B. coriacea) with treatments and increase in copper content. Percent corrected mortality was highest (65.13) at T5. The species was capable of tolerating high concentrations of copper and could be good candidate for planting in copper contaminated soils. The studies indicate the role of fungi in bioremediation of copper contaminated soils and toxicity to white grubs.
