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.

    SELECTION AND EVALUATION OF RHIZOBIA ASSOCIATED WITH KHAIR (Acacia catechu Willd.) FROM NORTH WESTERN HIMALAYAN REGION
    (UHF, NAUNI, 2018-12) JHILTA, PRAKRITI; NEERJA, RANA
    ABSTRACT The intensive harvesting of forest resources have led to decreased nitrogen and organic matter content in the forest soils. Biological nitrogen fixation offers economic and sound means for reducing the requirement of nitrogenous fertilizers, thereby restoring the degraded ecosystem. The present investigation entitled “Selection and evaluation of rhizobia associated with khair (Acacia catechu Willd.) from north western Himalayan region” was carried out in the Microbiology Laboratory of Department of Basic Sciences during the years 2016-2018. The study revealed that among 10 seed sources, Una seed source of Himachal Pradesh and Udham Singh Nagar of Uttrakhand were found best for seed, pod, germination and seedling parameters. It is evident from the studies that large seeds have greater per cent germination than small seeds. Non significant variation between pod and seed traits with geographical factors were noticed which indicated non clinal variation. A total of 65 isolate 27 from Himachal Pradesh and 38 from Uttrakhand were isolated from nodules of A. catechu. Out of 65, 46 isolates 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. Among 46 rhizobial isolates, 35 were P-solubilizers, 21 were siderophore producers and only 6 were HCN producers. Among these isolates, maximum Psolubilization (175.0 µg/ml), siderophore production (65.23%) and IAA (76.00 µg/ml) werer recorded with AUB5 isolate from Himachal Pradesh. Whereas, maximum P-solubilization (165.0 µg/ml), siderophore production (54.36%) and IAA (68.00 µg/ml) was recorded for AUP2 isolate from Uttrakhand. These two isolates namely AUB5 and AUP2 also showed antagonism against Fusarium graminearum, Pythium aphanidermatum, Alternaria, Rhizoctonia solani, Fusarium oxysporum, and Colletotrichum capsici. On the basis of plant growth promoting traits and antifungal activities two isolates AUB5 and AUP2 were selected and applied as biofertilizers which had significantly increased shoot biomass, root biomass, nodulation status and NPK content of soil over uinoculated control. Hence, these isolates have enormous potential to be used as biofertilizers for enhanced growth, nodulation status and protection of A. catechu and to sustain soil health under mid hills of NorthWestren Himalyan region.
