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 GENETIC DIVERSITY OF PHOSPHORUS SOLUBILIZING RHIZOBIA OF RAJMASH (PHASEOLUS VULGARIS L.)
    (UHF,NAUNI, 2019-11) GAUTAM, SWATI; KAUSHAL, RAJESH
    ABSTRACT The present investigations were conducted to determine the genetic diversity of P-solubilizing rhizobia of rajmash by amplified ribosomal DNA restriction analysis (ARDRA). A total of 50 isolates associated with rajmash 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 and plant infection test. Out of 50 rhizobial isolates, all were P-solubilizers, sixteen were siderophore producers, nine were HCN producers, eight isolates showed antagonism against Rhizoctonia solani Kuhn and five against Colletotrichum lindemuthianum Sacc. and Mangus. The maximum P-solubilization (295.74 µg/ml) was recorded for isolate KS and maximum IAA production (83.19 µg/ml) was noted for isolate Har4. Maximum siderophoreproduction with zone size of 19mm was recorded with the isolate Shl7 on CAS medium. On the basis of banding pattern generated through ARDRA analysis using restriction enzymes Alu I and Msp I, 19 isolates from agro-climatic zone-II were grouped into seven major phylotypes at 49 per cent similarity level, 15 isolates from agroclimatic zone-III were segregated into five major phylotypes with 49 per cent similarity and 16 isolates from agro-climatic zone-IV were grouped into seven major phylotypes at 57 per cent similarity level. Seed bacterization with 10 selected rhizobia resulted in significant increase in shoot height, root length, plant biomass and number of nodules over uninoculated control. Among 10 sequenced rhizobia, 4 isolates viz. Hab3, BhrB, Tis2 and San1 were identified as Rhizobium nepotum, 3 isolates viz. KAF, Har1 and Kal3 as Rhizobium indigoferae, isolate KS as Rhizobium etli, isolate Har2 as Rhizobium acidisoli and isolate Shl3 as Rhizobium pusense. Seed bacterization with R. etli strain KS+70% P showed considerable effect on increase in shoot height (86 cm), root length (28.30 cm), number of nodules (55.07 no./plant) and available NPK over uninoculated control at flowering stage as well as harvest of the crop.
