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 ROOT COLONIZATION OF APPLE PLANT BY POTENTIAL Pseudomonas SPECIES IN REPLANT SITES
    (2013) KUMARI, MANORMA; KAUR, MOHINDER
    ABSTRACT In the present study, isolation and characterization of indigenous fluorescent Pseudomonas strains from normal and replant site of apple orchard (Shimla H.P.) was done. Root colonizing bacteria that exert beneficial effects on plant development via direct or indirect mechanisms have been defined as plant growth promoting rhizobacteria (PGPR) The aim of the study to select and to develop PGP strains of fluorescent Pseudomonas species having efficient root colonizing capacity with direct and indirect plant growth promoting activities for management of replant problem of apple. The fourteen Pseudomonas species isolates were screened out for various plant growth promoting activities like siderophores, phosphate solubilization, antifungal activity, plant growth regulators (auxins, cytokinins and gibberellins), lytic enzymes and production of HCN and ammonia. On the basis of PGPR activities, nine isolates were genotypically characterized by RAPD and 16S rRNA gene sequencing. Out of them, two best isolates (Pn-13-San and An-16-Kul) were selected for 16S rRNA gene sequencing. Pn-13-San showed 99% homology with Pseudomonas aeruginosa M18 with accession number (NC_017548). An-16-Kul showed 99% homology with Pseudomonas aeruginosa PAO1 with accession number (NC_002516.2). These two strains exploited for the management of replant problem of apple in replant site at Maggota (Shimla). In replant field these two strains used individually and their consortia for treatment of apple rootstocks before planting. The performance of apple plants was much better in terms of root colonization capacity, plant establishment and increase in plant growth in terms of plant height, number of nodes and branches, chlorophyll content of leaves and NPK of rhizosphere soil over their respective control after nine and twenty months of plantation. These strains can be further exploited for management of replant problem of apple after conducting few more field trials in replant sites and can have great importance in the field of horticulture.
