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 PLANT GROWTH PROMOTING RHIZOBACTERIA ASSOCIATED WITH SEABUCKTHORN (Hippophae rhamnoides)
    (2013) ANIL, KUMAR; SHIRKOT, C.K.
    ABSTRACT The ability of a few soil microorganisms to convert insoluble forms of phosphorus to an accessible form is an important trait in plant growth-promoting bacteria for increasing plant yields. Little is known about the composition of phosphate solubilizing bacterial (PSB) diversity associated with rhizosphere of medicinal plant. Therefore, the present study was aimed to explore the diversity of P-solubilizing bacterial communities colonizing the rhizosphere soil and roots of medicinal plant seabuckthorn grown in natural conditions for the plant growth promoting activity towards the development of microbial inoculants for different crops grown in normal and stressed region. One hundred and six phosphate solubilizing bacteria were isolated by using culture dependent procedure from rhizosphere soil and endorhizosphere of seabuckthorn of two locations viz., Lahaul & Spiti of Himachal Pradesh. All the PSB isolates were screened for plant growth promoting traits (PGPT), including IAA production, siderophore, HCN, ability to grow on nitrogen free medium and antifungal activity. IAA production was detected in 74.52%, siderophore synthesis in 26.42%, HCN in 43.39%, nitrogen fixing ability in 65.85% isolates. Inhibition against A. solani was detected in 46.22% isolates and 25.47% of isolates had ability to inhibit the growth F. oxysporum. Out of total P-solubilizing bacterial isolates, fourteen isolates were selected on the basis of dendrogram derived from similarity coefficient among PGP traits. Isolates LU45* accumulate maximum phosphorus 239.24 μg/ml among selected 14 isolates along with other PGP traits (IAA, Siderophore, HCN, antifungal and lytic enzyme activity), therefore, selected for identification and characterization of different culture conditions for in vitro TCP solubilization. However, isolate T2R was morphologically different among all other isolates with a unique ability to produce red pigment, showed maximum PSI (5.0) and therefore, isolate T2R was also characterized phenotypically, biochemically and molecular based characterization. For net house studies, six isolates with PGPT were evaluated for their effect on early growth of tomato seedlings. Isolate T76* showed maximum per cent increase in root length, shoot length, root & shoot dry weight and vigour index and was also selected for identification. On the basis of results obtained from 16S rDNA analysis, isolate LU45*, T2R, T76* was identified as Bacillus subtilis CKS1, Serratia sp. AS2, Bacillus sp. AS3 respectively. Present study first time reported Serratia sp. from rhizosphere of seabuckthorn. Thus, the ability of performing multifarious plant growth promoting activities in tandem suggest PSB isolates for plant growth promotion and has significance to develop a cost-effective ecofriendly multifunctional biofertilizer.
