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 SELECTED PLANT GROWTH PROMOTING RHIZOBACTERIA ON GROWTH AND YIELD OF CAPSICUM (Capsicum annuum L.)
    (2011) GUPTA, SHWETA; KAUSHAL, RAJESH
    ABSTRACT Plant growth promoting rhizobacteria (PGPR) refers to rhizosphere bacteria that colonize plant roots in the competitive environment and enhance the crop growth as well as productivity by exerting beneficial effects through direct and indirect mechanisms. Capsicum is a renumerative crop to the farmers and is grown in both open fields and protective structures. The nutrient requirements and its sensitivity to extremes of environment coupled with higher incidence of diseases such as Damping off (Pythium spp.), Phytophthora blight (Phytophthora spp.), fruit rot (Colletotrichum spp.) and pests infestation resulted in sizeable yields loss in mid hills of Himachal Pradesh. The use of PGPR to supplement chemical fertilizers and pesticides is a potential alternative but no commercial formulation is available for use. So, the present investigations entitled “Studies on selected plant growth promoting rhizobacteria on growth and yields of Capsicum (Capsicum annuum L.)” was carried out during 2009-2011. Rhizosphere and root samples of capsicum were collected from four locations i.e. Taradevi, Theog, Nauni and Lanachetah in Shimla and Sirmour districts of H.P. A total of 56 isolates were isolated by using modified replica plate method. On the basis of colony morphological similarities 10 isolates were selected for screening of possession of multifarious plant growth promoting traits. Out of 10 isolates, only 6 isolates were selected for net house studies. Among which RS7 isolate possesses maximum plant growth promoting attributes like P-solubilization (80.0%) on PVK solid medium, (201.67 μg/ml) in broth, growth on Jensen medium, siderophore production (83.3%), auxin production (28.33 μg/ml), HCN production and antagonism against Pythium spp. (41.7%), Phytophthora spp. (42.5%) and Colletotrichum spp (40.1%). On the basis of morphological (Gram +ve rods), physiological (optimum growth at 35 ° C and 7 pH) and biochemical characteristics (Glucose fermentation, production of gelatinase and catalase enzymes) RS7 isolate tentaviley identified as Bacillus spp. Seed bacterization with RS7 isolate not only showed maximum increase in plant parameters such as shoot length (50.7% 41.6% and 8.0%), shoot biomass (48.5%, 39.8% and 10.1%), root length (49.0%, 39.7% and 3.6%), root biomass (45.1%, 37.9% and 10.2%) and yields (51.4%, 51.3% and 5.7%) over C1 (uninoculated absolute control), C2 (uninoculated fungicide control) and C3 (reference strain; PM9) treatments, respectively but also increased available N, P and K by 23.8%, 21.1% and 15.1%, respectively over innitial contents. On the basis of efficacy i.e. rhizocompetence and plant growth promoting efficiency under net house studies the bacterial isolate RS7 has good potential to be used as biofertilizer and biocontrol agent for Capsicum.
