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.

    EPIDEMIOLOGY AND MANAGEMENT OF STEMPHYLIUM BLIGHT OF GARLIC
    (UHF, NAUNI, 2018-10) BHARDWAJ, CHIDEMBRA; KANSAL, SANDEEP
    ABSTRACT Stemphylium blight caused by Stemphylium vesicarium (Wallr.) E. Simmons is an important destructive disease among various other diseases. It appears every year in moderate to severe form in different garlic growing areas of Solan and Sirmaur districts of Himachal Prdaesh. The causative fungus isolated from infected leaves of diseased plants grew in the form as off white mycelium, which later turned golden brown and finally velvety on PDA. Conidia were oblong to oval, light to olive brown in colour, produced on straight to variously curved cylindrical conidiophores. Thus, based upon morphological and cultural characters, the causative fungus was identified as Stemphylium vesicarium (Wallr.) E. Simmons. The pathogenicity tests revealed peculiar symptoms as small white to yellow flecks which later turned into lesions tan brown in colour and expanded along the leaf blade, giving blighted appearance to the leaves. Epidemiological studies revealed that the temperature of 25ÂșC, inoculum concentration of 6x104 conidia/ml, leaf wetness period of 72 h and relative humidity of more than 90 per cent were optimum for the rapid progression of disease reflecting significant higher infection rate under artificial epiphytotic conditions. Under field conditions, disease was affected by variation in weather variables, as dry and moist weather coupled with intermittent rains favoured the progression of Stemphylium leaf blight disease. Twelve genotypes were tested against Stemphylium blight disease of garlic. None of the genotypes tested was found immune or resistant to the disease whereas, Kandaghat Selection was found moderately resistant against the disease. In vitro evaluation of fungicides indicated Folicur (tebuconazole), and Companion (carbendazim+mancozeb) as potent mycelial growth inhibitors of S. vesicarium. Field evaluation studies inferred the application of three foliar sprays of Folicur (tebuconazole) @ 0.1 per cent at ten days interval started with the initiation of disease to be most efficacious in limiting Stemphylium blight of garlic (71.5%) and enhancing the bulb yield (145.7q/ha) with ICBR ratio of 1:9.1.
