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.

    ISOLATION AND CHARACTERIZATION OF PLANT GROWTH PROMOTING RHIZOBACTERIA (PGPR) FROM TURMERIC (Curcuma longa L.)
    (2013) BALKAR, SINGH; KAUSHAL, RAJESH
    ABSTRACT Plant growth promoting rhizobacteria (PGPR) due to myriad plant growth promoting/stimulating traits have become an emerging area of research and important commercial agro-input in past two decades. They have acquired a strategic place in sustainable agriculture development around the globe. Supplementation of chemical fertilizers by PGPR can reduce chemical input upto 25-30%. Beside this PGPR also provides a low cost eco-friendly way of detoxification and bioremediation of soil. Hence, investigation entitled “Isolation and characterization of plant growth promoting rhizobacteria (PGPR) from Turmeric (Curcuma longa L.)” was carried out during the years 2010-12 for the development a potential bio-inoculum for turmeric crop growing in low mid hills of Himachal Pradesh. The rhizospheric soil samples, rhizome/root samples of Turmeric (Curcuma longa L.) plants were collected from Kangra (31º2 to 32º5 N and 75º to 77º45 E) and Hamirpur (31º25 to 31º52 N and 76º18 to 76º44 E) districts of Himachal Pradesh. Using modified replica plating technique a sum of 27 isolates were selected and purified. Only 7 isolates out of 27 isolates were selected for net house studies, on the basis of various PGPR traits (N-fixation, P-solubilization, sidrophore, HCN and auxin production) and antagonism against Pythium spp. and collectotrichum spp. causing rhizome rot and leaf spot respectively. Bacterial isolate A10 showed maximum P-solubilization qualitative (81.5%) and quantitative (128.8μg/ml) as well, growth on Jensen’s medium, sidrophpre production (103.7%), IAA production (29.4μg/ml), HCN production and antagonism against Pythium spp.(41.4%) and collectotrichum spp.(39.3%). Bacterial isolate A10 tentatively identified as Bacillus spp. on the basis of its morphological, physiological and biochemical characteristics. Plants bacterized with isolate A10 showed significantly increase in leaf number (33.1%), shoot length (16.5%), shoot biomass (28.4%), root length (29.2%), root biomass (52.3%), rhizome size (58.8%) and rhizome yield (54.6%) over uninoculated control, along with maximum NPK uptake and availability. Biofertization and bioprotactant characters of selected bacterial isolate A10 (Bacillus spp.) paved the way of its use at commercial level to supplement chemical fertilizers for enhance production after conducting multilocational field trial in different agro-climatic zones of the state.
