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.

    COMPARISON AND PRELIMINARY CHARACTERIZATION OF SIDEROPHORES PRODUCING FLUORESCENT PSEUDOMONADS DIVERSITY IN REPLANT PROBLEM AND NORMAL SITES OF APPLE AND PEAR
    (2010) LIMBU, SHEFALI; KAUR, MOHINDER
    ABSTRACT The present study attempted to identify and characterize fluorescent Pseudomonas species isolated from rhizosphere of apple and pear growing in normal and replant sites of Chamba distt.. and to optimize and maximize its siderophore production, its purification and in vitro antagonistic action against phytopathogens. All Pseudomonas isolates showed additional features like production of antifungal metabolites, hydrogen cyanide, indole-3-acetic acid, protease enzyme and phosphate solubilization. Four Pseudomonas isolates (PN 3 BAK, PR 5 BAK, AN 4 BAK and AR 5 BAK) were selected for further production purpose after screening for siderophore activity. Siderophore production was optimum at temperature 300C, 72 h of incubation period, shake condition (90 rpm) and pH 7 in an iron free succinate media. An attempt was also made to purify and partially characterize siderophores produced by the four Pseudomonas isolates. Extraction by diethyl ether proved to be the best, giving only one peak with Dowex-50 column. The purified siderophores gave yellow spots with chrome azurol-S reagent in thin layer chromatography. Chemical characterization and spectrophotochemical detection of siderophore revealed that the type of siderophore was hydroxamate. Extracts from best selected Pseudomonas isolates showed positive antimicrobial activity against some fungal pathogens, viz., Sclerotinia sclerotiorum, Pythium sp.and Rhizoctonia solani. These strains showed their extensive inhibition effect against Xanthomonas campestris and Bacillus sp. These in vitro antimicrobial actions of Pseudomonas isolates against phytopathogens suggest the potential of the organism to serve as a biocontrol and plant growth promoting agents that could be used and further standardized for field trials for management of replant problem of apple and pear in Himachal Pradesh.
