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.

    Evaluation of antimicrobial compounds from Juniperus communis L. and Vitex negundo L. against Xanthomonas sp. and Pseudomonas sp.
    (YSPU, 2015) Digvijay; Bhardwaj, Satya Vrat
    Essential oils from the shade dried leaves of Juniperus communis L. and Vitex negundo L. from H.P. (India) were examined for their antimicrobial activities against eight human and plant pathogenic bacteria. Essential oils were obtained by using Soxhlet extraction apparatus. Chemical analysis of the oils was done by using gas chromatography and mass spectrometry (GC/MS). The antimicrobial effects were tested by inhibition zone diameter (IZD)/ zone of inhibition test. Essential oil from methanol extract showed very good activity at 300 ppm concentration after 72 hours and was more effective as compared to others, however, all the plant extracts showed inhibitory effect on linear growth of selected microorganism. Higher concentrations of 1-Phenanthrene carboxylic acid (11.44 %) and Propylparaben, Benzoic acid, 4-hydroxy, Benzoic acid, 3-hydroxy and Benzoic acid, 3- hydroxy-2-methylpropyl ester (23.23%) content released from Juniperus communis L. and Vitex negundo L. H.P. (India) respectively, might be assigned to be responsible for such excellent antimicrobial activity against the tested pathogens. Docking studies were also performed for sixteen compounds in order to evaluate their affinity to bacterial proteins that are known targets for some antibiotics with different mechanisms of action. The purpose of the present studies was to encourage use of Juniperus communis L. and Vitex negundo L. essential oils against bacterial infections so as to provide an approach to develop herbal formulations as potential disease management strategies in place of chemicals. However, the results are yet to be authenticated through wet lab experimentations for each biomolecules before going ahead for potential drug development.
