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.

    Preliminary characterization of fluorescent Pseudomonas diversity producing plant growth regulators in apple and pear
    (2010) KAPOOR, RITIKA; KAUR, MOHINDER
    ABSTRACT Under the present study, an attempt was made to study production of bacterial plant growth regulators viz. auxins, gibberellins and cytokinins produced by indigenous strains of Pseudomonas species isolated from the rhizosphere of apple and pear. They all were screened out for the production of different plant growth promoting activities like antifungal, siderophores, phosphate solubilization, HCN, ammonia and protease. Four strains each of Pseudomonas species (PN-4-SAN, PN-10-SAN, AN-2-NAG, AN-4-NAG ) were selected for further studies with the aim to find out best indigenous plant growth regulators producing bacterial strains for application in field in order to increase yield and crop productivity and also to find out industrially important strains for production of plant growth regulators viz. auxins, gibberellins and cytokinins. The selected Pseudomonas isolates preferred nutrient broth for the growth and production of all three growth regulators. All the four strains produced maximum plant growth regulators at 72 h incubation period at pH 7.0 under shake condition while the optimum temperature for production of growth regulators was 28oC. An attempt was also made to extract, purify and evaluate plant growth regulators by thin layer chromatography, by spectrophotometric and specific bioassay method. By TLC, auxins gave pink spot gibberellins gave grey spot and cytokinins gave brown spot upon spraying with Salper reagent, solvent water: sulphuric acid and iodine respectively. Specific bioassays viz. Avena coleoptile straight test, α-amylase release test and radish cotyledon bioassays showed increased length, enzyme activity and increase in weight of cotyledons.
