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.

    EVALUATION OF PHYTOSOCIOLOGICAL, NATURAL REGENERATION AND SITE CHARACTERISTICS OF Rhododendron campanulatum D. Don IN ALPINE REGION OF WESTERN HIMALAYAS
    (UHF,NAUNI, 2020-08) BHISHAM, DEV; VERMA, SUBHASH CHANDER
    ABSTRACT The efficacy of Metarhizium(=Nomuraea) rileyi (Farlow) Kepler, S.A. Rehner and Humber was studied against different larval instars of Helicoverpa armigera (Hubner) by larval dip method. M. rileyi when applied against different larval instars of H. armigera at concentrations between 102-108 conidia/ml resulted 20-96.67, 16.67-93.33, 20-83.33, 16.67- 76.67 and 13.33-53.33 per cent mortality of 1st, 2nd, 3rd, 4th and 5th instar larvae, respectively. LC50 and LC90 values for different instars were 5.51 x 103, 6.87 x 104, 2.81 x 105 and 5.55x 105 ; and 2.86 x 106, 1.56 x 107, 1.72 x 109 and 2.87 x 109 conidia/ml against 1st, 2nd, 3rd and 4th instar larvae, respectively. M. rileyi at 107 conidia/ml took 5.48, 6.26, 8.16 and 8.44 days to kill 50 per cent and 10.19, 9.88, 13.91 and 14.39 days to kill 90 per cent of 1st, 2nd, 3rd and 4th larvae of H. armigera, respectively. Azadirachtin (1.02ppm), azadirachtin (1.53ppm) and indoxacarb (0.72ppm) inhibited the growth of M. rileyi by 47.31, 62.47 and 72.39 per cent, respectively. However, M. rileyi at concentrations of 102 to 107 conidia/ml mixed with azadirachtin (1.02ppm) and indoxacarb (0.72ppm) and tested against second instar larvae resulted 10.34-96.55 (LC50: 1.09 x 104, LC90: 2.39 x 106 conidia/ml) and 14.29-92.86 per cent (LC50: 1.37 x 104, LC90: 6.73 x 106 conidia/ml) mortality, respectively. Similarly M. rileyi at concentrations of 103-108 conidia/ml impregnated with azadirachtin (1.53ppm) and indoxacarb (0.72ppm) tested against third instar larvae resulted 13.79-89.66 (LC50: 2.79 x 103, LC90: 3.12 x 108 conidia/ml) and 14.29-92.86 (LC50: 3.06 x 105, LC90: 1.11 x 109 conidia/ml) per cent mortality, respectively. M. rileyi (107 conidia/ml) alone or conidial suspension mixed with azadirachtin (1.02 and 1.53ppm) and indoxacarb (0.72ppm) resulted non-significant effect on days to mortality of 2nd and 3rd instar larvae of H. armigera. Hence M. rileyi can be used as one of the component of IPM programme for eco-friendly management of H. armigera after field evaluation.
