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 DIVERSE PLANT GROWTH PROMOTING RHIZOBACTERIA ASSOCIATED WITH RHIZOSPHERE OF KIWI VINES
    (2015) SHARMA, MALVIKA; SHIRKOT, C.K.
    ABSTRACT Plant hormones are chemical messengers that affect a plant's ability to respond to its environment. Hormones are organic compounds that are effective at very low concentration; they are usually synthesized in one part of the plant and are transported to another location. Botanists recognize five major groups of hormones: auxins, gibberellins, ethylene, cytokinins, and abscisic acid. IAA (indole-3-acetic acid) is the member of the group of phytohormones and is generally considered the most important native Auxin. It functions as an important signal molecule in the regulation of plant development including organogenesis, tropic responses, cellular responses such as cell expansion, division, differentiation, and gene regulation. Therefore, the objective of the present study was to isolate and screen IAA producing rhizobacteria from kiwi vines and to optimize cultural conditions for maximum production of IAA. One hundred and fifty seven isolates (sixty three rhizospheric and ninety four root endophytic isolates were isolated from different cultivars of kiwi vines and were screened for IAA production. These IAA producing isolates were further screened for P-solubilization on PVK media, siderophore production on CAS medium and their ability to grow on nirtrogen free medium. Overall maximum IAA producing twenty isolates were selected for screening of other PGP traits. Variation was also observed in their plant growth promoting (PGP) activities such as IAA production, P-solubilization and siderophore production. Out of twenty, majority isolates exhibited antifungal activity and showed enzyme production. Overall six most efficient bacterial isolates were finally selected and evaluated for plant growth promotion of tomato and kiwi seedlings under net house conditions. The most efficient isolate B2S10 was further subjected to optimization of cultural conditions for IAA production. Maximum IAA production of (55μg/ml) was observed after 96 hours of incubation at 35⁰C temperature, pH 9 in LB broth amended with 1.00 (%) tryptohan. The most efficient isolate was identified as Serratia marcescens by 16SrRNAgene sequence analysis
