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.

    ROLE OF BOTANICALS IN MANAGEMENT OF Meloidogyne incognita (Kofoid and White)Chitwood ASSOCIATED WITH TOMATO(Solanum lycopersicum L.)
    (2016) JOGUR, ABHIJEET; KHANNA, ANJU SUDHAKAR
    ABSTRACT The research explorations entitled ‘Role of Botanicals in Management of Meloidogyne incognita (Kofoid and White) Chitwood associated with Tomato (Solanum lycopersicum L.)’ were undertaken to record the efficacy of certain botanicals known to possess nematicidal principles in different forms against Meloidogyne incognita infecting tomato crop. In all, nine plants viz., Azadirachta indica (Neem), Calotropis procera (Calotropis/ aak), Lantana camara (Lantana), Parthenium hysterophorus (Congress grass), Tagetes erecta (African marigold), Allium sativum (Garlic), Duranta erecta (Duranta), Melia azedarach (Darek) and Ricinus communis (Castor) were used during the present studies. In vitro studies regarding effect of aqueous leaf/seed extracts of referred plants at one, two and five per cent concentrations on juvenile hatch from egg mass revealed garlic clove extract at five per cent to be the best egg hatch inhibitor closely followed by calotropis leaf extract. However, at lower concentrations aak leaf extract was more effective than garlic clove extract. On the other hand, among the leaf extracts neem caused highest per cent mortality of J2s under in vitro conditions at all durations of exposure followed by calotropis, parthenium, tagetes and lantana in decreasing order of efficacy. Among seed extracts, garlic at five per cent concentration was the most effective causing cent per cent mortality within 120 hours. In a pot experiment, seedling root dips in five per cent extracts of referred plants separately, followed by their transplanting in nematode infected soil applied with respective extracts produced the best results showing improvement in vegetative growth and tomato fruit production and reduction the soil populations of the juveniles and root galling significantly with respect to control. The highest yields were attained in treatments receiving garlic clove or neem leaf extract. In a field experiment with dried powders of six plants, soil treatment with dried neem leaf powder produced most vigorous plants that yielded highest quantum of fruits followed by calotropis, castor, lantana, parthenium and duranta in decreasing order of efficacy.
