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.

    MANAGEMENT OF ALTERNARIA LEAF SPOT OF CAULIFLOWER THROUGH INNOVATIVE METHODS
    (COLLEGE OF HORTICULTURE AND FORESTRY, DR Y S P UHF, NERI, HAMIRPUR, 2019-12-13) CHANDEL, SHAVANA; SHARMA, MONICA
    Alternaria leaf spot of cauliflower occurs worldwide but its prevalent is more in subtropical and temperate areas. The disease causes heavy losses to the crop. In the present investigations, periodic surveys were conducted at various locations in Hamirpur, Mandi, Bilaspur, Kangra, Una, Solan and Kullu districts of Himachal Pradesh and disease incidence from 48 to 85 per cent and disease index from 66 to 69 per cent was recorded. In pathogenicity test, incubation period of 72 h was observed with spray inoculation on 35 days old seedlings. For the management of disease, eight different abiotic resistance inducers were evaluated against the disease under pot conditions and it was found that salicyclic acid (20 mM) was found most effective with 33.67 and 54.46 per cent disease reduction in disease incidence and disease index with plant weight 9.5 kg/plant. Out of five aqueous biopesticides tested under in vitro conditions, Eucalyptus sp. and Azadirachta indica was found most effective at 50 per cent concentration with 82.37 and 79.23 per cent mycelial inhibition, respectively. Among five cow-urine based biopesticides evaluated under in vitro conditions, mycelia growth was not observed in cow-urine alone and cow-urine based biopesticide of Azadirachta indica and Eucalyptus sp at 10 and 15 per cent concentration. Under pot conditions, out of all biopesticide, Azadirachta indica was found to be most effective. Eight different fungicide were tested under in vitro conditions and it was found that azoxystrobin 25 %, azoxystrobin 20 % + difenconazole 12.5 %, zineb 68 % + hexaconazole 4 %, metiram 55 % + pyraclostrobin 5 %, difenconazole and hexaconazole were found most effective and significantly superior among all the treatments with complete inhibition. Foliar spray with zineb + hexaconazole, hexaconazole and azoxystrobin + difenconazole was observed to manage the disease effectively under pot condition.
