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 PLANT GROWTH PROMOTING RHIZOBACTERIA AT VARYING LEVELS OF N AND P ON CAULIFLOWER (Brassica oleracea var. botrytis L.)
    (2011) KAUSHAL, MANOJ; KAUSHAL, RAJESH
    The present investigations entitled “Effect of plant growth promoting rhizobacteria at varying levels of N and P on cauliflower (Brassica oleracea var. botrytis L.)” were conducted at Research Farm, Soil Microbiology Laboratory of Department of Soil Science and Water Management and RHRS-Bajaura, Kullu, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh during the years 20082010 to develop an effective inoculum of PGPR with multifarious plant growth promoting activities (Psolubilization, N- fixation, IAA, Siderophore, HCN production and antagonism against soil borne pathogens) to overcome problems of deficiencies of nitrogen, low availability of phosphorus and sensitivity of the crop to soil borne pathogens. Among a sub-sample of 60 isolates of PGPR isolated from the rhizosphere/ endorhizosphere of cauliflower from three (Bilaspur, Hamirpur and Kangra districts) naturally growing agro-climatic zones of Himachal Pradesh, only five efficient isolates were selected and characterized after a series of successful experiments under in vitro and net house conditions at varying levels of N and P fertilizers. The selected isolates were found positive towards majority of selected multifarious plant growth promoting traits and also had effective control against black rot, stalk rot and leaf spot diseases of cauliflower. On the basis of morphological, physiological and biochemical characteristics, isolates was presumptively identified as Bacillus spp. Thereafter, molecular characterization of the best native isolate was carried out with specific primers by taking genomic DNA and based on the 16S rRNA gene sequence the said isolate was identified as Bacillus pumilus. The application of selected isolate (MK5) at 75% recommended dose of N and P fertilizers level not only registered significant increase in yields by 26% (average of both the locations i.e. Kullu and Solan) over uninoculated control (recommended doses of NPK fertilizers) but also a saving of 25% N and 25% P fertilizers. The results of multilocations trials conducted (by taking the best treatment at both the locations i.e. MK5 + 75%NP) at three locations viz. RHRS-Bajaura, Kullu; UHF-Nauni, Solan and RHRS-Jachh, Kangra clearly depicts an increase of 8% (average of three locations) in curd yields over recommended levels of NPK fertilizers. The present studies, therefore suggests that PGPR are able to induce the production of IAA, solubilization of phosphorus and resistance to soil borne pathogens, thereby improving growth of plants. The conjoint use of PGPR inoculants with optimum doses of chemical fertilizers seems to be an efficient approach to reduce the use of chemical inputs (fertilizers and pesticides) for enhanced growth and yield without impairing the soil health for sustainable cauliflower cultivation in Himachal Pradesh.
