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.

    STUDIES ON PRODUCTION AND ANTIMICROBIAL PROPERTIES OF Volvariella volvacea (Bull.Ex.Fr.) Sing
    (COLLEGE OF HORTICULTURE AND FORESTRY, DR Y S P UHF, NERI, HAMIRPUR, 2019-10-23) SHARMA, SHIVANI; JARIAL, R S
    The present investigations entitled “Studies on production and antimicrobial properties of Volvariella volvacea (Bull.Ex.Fr.) Sing’’ was undertaken to evaluate various cultural requirements for the vegetative growth of different strains of V. volvacea, to evaluate different locally available substrates for the production of different strains of V. volvacea and to study antimicrobial properties of different strains of V. volvacea against five human pathogenic bacteria viz., E. Coli, Proteus sp., Bacillus sp., Pseudomonas sp. and Streptococcus sp. Among five liquid media studied, malt extract was found to be the best medium for the growth of all the strains of V. volvacea both in solid (38.92 mm) as well as liquid (2625.42 mg) phase. Out of five different pH levels evaluated for the growth of different strains of V. volvacea, pH 7.0 (30.75 mm) was observed to be the best pH for the growth of all the strains of the test fungus. Out of five different temperature regimes evaluated, 30°C (41.78 mm) was observed to be the ideal temperature for the growth of V. volvacea. Out of four strains under study DMR-484 was observed to grow best in all the nutrient media (Solid; 41.38 mm and Liquid; 1780.67 mg), different pH levels (29.64 mm) and different temperature regimes (37.00 mm) studied. In production trials, among five different substrates, cotton waste was observed to be the best substrate in terms of spawn run period (8.25 days), time taken for first flush (13.91 days), number of fruit bodies (35.50/bed), yield (472.91 g/Kg) and biological efficiency (15.76%). The aqueous and methanolic extracts of the mycelium of strain DMR-484 were found to have antimicrobial activities against E. coli with average zone of inhibition 10.33 mm and 13.00 mm, respectively. However, mycelia of all other strains were unable to inhibit any of five human pathogenic bacteria under study. Further, it was also found that none of the four fruit body extracts of all the strains under study exhibited antimicrobial activity against any of the human pathogenic bacteria.
