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.

    EFFECT OF CO-INOCULATION OF PLANT GROWTH PROMOTING RHIZOBACTERIA AND CHEMICAL FERTILIZERS ON RHIZOBACTERIAL COMMUNITY STRUCTURE AND FUNCTION OF TOMATO (Solanum lycopersicum L.)
    (UHF,NAUNI, 2017-09) KAMINI; CHAUHAN, ANJALI
    ABSTRACT Plant growth promoting rhizobacteria are the soil bacteria inhabiting around/on the root surface and are directly or indirectly involved in promoting plant growth and development via production and secretion of various regulatory chemicals in the vicinity of rhizosphere. Generally, plant growth promoting rhizobacteria facilitate the plant growth directly by either assisting in resource acquisition (nitrogen, phosphorus and essential minerals) or modulating plant hormone levels or indirectly by decreasing the inhibitory effects of various pathogens on plant growth and development in the forms of biocontrol agents. The plant-beneficial rhizobacteria may decrease the global dependence on hazardous agricultural chemicals which destabilize the agro-ecosystems. PGPR are commonly used as inoculants for improving the growth and yield of various agricultural crops. Beneficial effects by introduction of specific microorganisms as PGPR on plant growth have been reported for numerous vegetable crops including tomato, capsicum, cauliflower and other crops grown under field conditions In the present study, PGPR (Bacillus subtilis strain 21), isolated from tomato crop with wide range of PGP traits viz., phosphate solubilization, siderophore production, HCN and IAA production was used as an inoculant to study its efficacy on growth and yield of tomato under field conditions (at variable concentration of chemical fertilizers). The PGPR Bacillus subtilis inoculation with 100% NPK showed significant increase in various growth parameters viz root length (50.94 %), shoot length (22.9 %), plant biomass (92.37 %), number of fruits per plant (61.02 %), average fruit weight (12.04 %), yield (88.61 %), ascorbic acid content (41.63 %) and TSS content (12.8 %) over control was recorded. Inoculation with PGPR enhances resident bacterial community and hence showed significant increase in bacterial population associated with tomato rhizosphere and endorhizosphere. A total of sixty five bacterial isolates were screened for P-solubilization, antifungal activity, HCN, siderophore and IAA production. On the basis of these activities, thirty one bacterial isolates were analysed for genetic diversity of ARDRA analysis. All the isolates were grouped into three major phylotypes at 75 % similarity level. The representative bacterial isolates from each phylotype were identified by 16S rDNA sequencing and identified species were Acinetobacter calcoaceticus, Pseudomonas sp., Pseudomonas aeruginosa, Serratia marcescens, Enterobacter sp. and Bacillus sp. Thus, the results of this study provides comprehensive information on the ability of Bacillus subtilis strain S21 significantly enhance the plant growth promotion of tomato when supplemented with chemical fertilizers and diversity analysis of resident rhizobacterial community.
