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.

    EFFICIENCY OF PLANT GROWTH PROMOTING RHIZOBACTERIA FOR THE ENHANCEMENT OF TOMATO GROWTH
    (2012) SHARMA, RASHMI; SHIRKOT, C.K.
    ABSTRACT Plant growth promoting rhozobacteria (PGPR) are known to influence plant growth by various direct or indirect mechanisms. Environmental protection and the need to enhance agricultural output have made research in new sustainable technologies necessary. As in most sectors of agriculture, there is increasing demand for organic tomatoes. Therefore, the overall strategy for increasing crop yields, sustaining them at a high level and maintaining proper soil health must include an integrate approach to develop effective and more consistent active plant growyh promoting rhozobacteria (PGPR) inocula, because, there is a considerable experimental support for the idea that PGPR may be used as biofertilizers and biocontrol agent to increase the early growth of tomato seedlings in the nursery and subsequently the yield with concomitant decrease in the chemical fertilizers and pesticides. Therefore, the aim of this study is to screen the indegeneous plant growth promoting rhizobacterial isolates for multifarious plant growth promoting traits and to determine the effect of inoculation with PGPR’s on growth of tomato seedlings in filter paper assay and in soil less medium under growth chamber. The bacterial strains were characterized for plant growth promoting activities and antifungal-antibiotic activities under in vitro conditions. Seed bacterization with bacterial strains increased the germination percent and overall root/shoot parameters of tomato seedlings in filter paper assay and under growth chamber. Among twenty seven bacterial strains, including refrence strain, isolate S2 showed significant effect in filter paper assay with maximum increase in per cent germination, root length, plant dry weight and vigour index. Isolate *S25 showed maximum increase in root length, root dry weight, shoot dry weight and plant biomass in growth chamber. *S25 also possessed maximum P-solubilization, maximum IAA production, siderophore synthesis, chitinase activity, protease activity, ability to fix atmospheric nitrogen and antifungal activity against Alternaria solani, D.necatrix and Sclerotium rolfsii. Therefore, *S25 strain had considerable growth promotion and biocontrol ability, and it could be used as a biofertilizer or biocontrol agent.
