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.

    PHOSPHATE SOLUBILIZING POTENTIAL OF PLANT GROWTH PROMOTING RHIZOBACTERIA (PGPR) ISOLATED FROM TOMATO SEEDLINGS
    (2009) SHARMA, NIPUN; SHIRKOT, C.K.
    ABSTRACT Phosphate solubilizing microorganism play an important role in supplementing phosphorus to the plants by several mechanisms like lowering of pH by acid production and ion chelation and thus benefit plant growth and development. Therefore, the aim of this study was to determine the phosphate solubilizing potential of plant growth promoting rhizobacteria (PGPR) isolated from tomato seedlings. Twenty three bacterial isolates were selected (by modified replica plating technique) as the representative of the total plated population from the rhizosphere soil and roots of the tomato seedlings grown in nursery at different locations of Hamirpur district. All the bacterial isolates were able to grow simultaneously on nutrient agar, Pikovskaya’s, nitrogen free media and selected for further screening for various plant growth promoting activities. Twelve phosphate solubilizing bacterial isolates exhibited concurrent IAA production and antifungal activity against Alternaria solani, Fusarium oxysporum and Pythium aphanidermatum. Seventeen isolates were found as good siderophore producers. After screening, four isolates were selected for ability to solubilize tricalcium phosphate (TCP) in PVK broth and for antifungal activity against A. solani. Isolate TE5 showed maximum P- solubilization (145.40 mg/l) and maximum per cent growth inhibition (75.33%) at pH 7.5, 0.5 per cent TCP concentration, after 72 h of incubation at 350C. In net house and growth chamber studies also, TE5 showed maximum germination (%), germination energy index (%), vigour index, shoot length, root length, shoot dry weight and root dry weight and was higher in the seedlings treated with bacterial isolates as compared to the untreated control. N, P and K content of soil and whole shoot system was found maximum in TE5 treated seedlings, closely followed by other bacterial strains and higher as compared to the untreated control. The present study, therefore, suggests that the use of phosphate solubilizing bacteria as inoculant biofertilizers might be beneficial for tomato cultivation and has significance to develop cost effective ecofriendly sustainable system in the management of environmental and agricultural problems.
