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.

    CANOPY MANAGEMENT OF REJUVENATED APPLE TREES THROUGH PRUNING AND PROHEXADIONE-Ca TREATMENTS
    (2016) CHAUHAN, AMAN; MANKOTIA, M. S.
    ABSTRACT The present investigation entitled “Canopy management of rejuvenated apple trees through pruning and prohexadione-Ca treatments” was carried out at Regional Horticultural Research and Training Station, Mashobra, Shimla during the years 2015 and 2016. Pruning treatment with no heading back-only thinning out suppressed the vegetative growth and markedly improved the fruit set, yield and yield efficiency. It also improved red colouration and firmness of the fruits at harvest. Heading back (25% removal of one year old growth) increased vegetative growth and improved fruit quality in terms of size and total soluble solids. Two foliar applications of prohexadione-Ca at a concentration of 150 ppm significantly restricted the vegetative growth. Further, it was found to be effective in improving fruit set, yield efficiency, fruit colour and firmness. Return bloom on the basis of blossom density was improved by combining no heading back-only thinning out pruning cuts with two foliar applications of prohexadione-Ca at a concentration of 150 ppm. In order to regulate vegetative growth and fruiting in rejuvenated apple trees, the combination of no heading back-only thinning pruning cuts and two foliar applications of prohexadione-Ca at a concentration of 125 ppm and 150 ppm can be recommended for sustainable apple production.
