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.

    CHARACTERIZATION OF PLANT GROWTH PROMOTING RHIZOBACTERIA ISOLATED FROM THE RHIZOSPHERE OF APRICOT (Prunus armeniaca)
    (2013) SHARMA, KRITIKA; SHIRKOT, C.K.
    ABSTRACT Phosphorus (P) is considered the second most essential macronutrient following nitrogen. Plants acquire phosphorus from soil solution as phosphate anion. Phosphorus solubilizing bacteria play role in phosphorous nutrition by enhancing its availability to plants through release from inorganic and organic soil P pools by solubilizing and mineralization. Therefore, the aim of this study was to determine the phosphate solubilizing potential of plant growth promoting rhizobacteria (PGPR) isolated from apricot trees. One hundered and eighty eight bacterial isolates were selected (by replica plating technique) as the representative of the total plated population from the rhizosphere soil and rhizome/roots of the apricot trees from mid hill and high hills region of Himachal Pradesh. All the bacterial isolates were able to grow simultaneously on nutrient agar, Pikovskaya’s, nitrogen free media and CAS media and selected for further screening for various plant growth promoting activities. Seventy two P-solubilizing bacterial isolates (rhizospheric and endorhizospheric) were further studied for different activities such as IAA production, Siderophore production, HCN production and Antifungal activity. Variation was also observed in type of siderophore (Hydroxymate and carboxylate), IAA, HCN and antifungal. Forty seven isolates exhibited antifungal activity against Dematophora necatrix. Out of seventy two isolates, fourteen were further screened for P-solubilization as well as other multiple PGP traits, further studies were carried out with isolate AG1(3) which produced 130.60 ug/ml of P-solubilization under un-optimized cultural conditions. Optimizing the cultural conditions after 72 h of incubation at 30ºC , at pH 7, 1.00% TCP concentration and 2.00% inoculums size resulted in significance increase in P solubilization by the isolate AG1(3), identified as Bacillus subtilis on 16S rDNA analysis. The present study, therefore suggest that the use of P-solubilizing bacteria as as bio-inoculant that might be beneficial for raising quality apricot plant in long term and to develop cost effective ecofriendly sustainable system for horticultural crops.
