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.

    GENETIC DIVERSITY OF ROOT NODULATING BACTERIA ASSOCIATED WITH PEA IN DIFFERENT AGRO-CLIMATIC ZONES OF HIMACHAL PRADESH
    (UHF,NAUNI, 2018-04) DIPTA, BHAWNA; KAUSHAL, RAJESH
    ABSTRACT The present investigations were conducted to determine the diversity of rhizobia with multiple plant growth promoting traits by amplified ribosomal DNA restriction analysis (ARDRA). A total of 72 isolates associated with pea were authenticated as Rhizobium spp. on the basis of different authentication tests, viz. congo red test, bromothymol blue test, growth in Hofer’s alkaline broth, ketolactose medium, glucose peptone agar and plant infection test. Out of 72 rhizobial isolates, sixty were P-solubilizers, forty eight were siderophore producers and only three were HCN producers. Forty six showed antagonism against Fusarium ultimum, forty against Pythium aphanidermatum and eighteen against Rhizoctonia solani. On the basis of different banding pattern generated through ARDRA analysis using Alu I and Msp I, 17 isolates from agro-climatic zone-I were grouped into three major phylotypes at 56.6 per cent similarity level, 21 isolates from agro-climatic zone-II were segregated into six major phylotypes at 55 per cent similarity level, 21 isolates from agro-climatic zone-III were grouped into seven major phylotypes at 55 per cent similarity level and 13 isolates from agro-climatic zone-IV were grouped into five major phylotypes at 32 per cent similarity level. Among 21 sequenced rhizobial isolates, 9 isolates (HS1, UR9, SP5, SS1, KB2, CS3, SJ6, KC2 and KC3) were Rhizobium spp., 5 isolates (KN2, MJ4, SN2, SK2 and SS3) were R. leguminosarum and 7 isolates (BD1, SNE2, SJ1, SJ8, LK2, LT2 and KS1) were R. leguminosarum bv. viciae. The maximum P-solubilization (305.40 μg/ml), siderophore production (84.32%) was recorded for R. leguminosarum bv. viciae strain LK2, Maximum IAA production (82.75) μg/ml was noted for R. leguminosarum bv. viciae SJ8. Seed bacterization with R. leguminosarum bv. viciae strain LK2 has significantly increased shoot, root length, number of nodules and available NPK over uninoculated control by 27, 76, 57, 15, 25 and 12 per cent, respectively.
