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.

ThesisItem Open Access DEVELOPMENT OF CULTIVATION PRACTICES OF Silybum marianum (L.) Gaertn. UNDER ORGANIC FARMING(UHF Nauni, 2024-07-20) NYAMKOI; Bhupender DuttThe present investigations on "Development of cultivation practices of Silybum marianum (L.) Gaertn. under organic farming," were carried out in the experimental field and laboratory of the Department of Forest Products, College of Forestry, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan (HP). Among the two seed sources of Silybum marianum procured from CIMAP, Lucknow and UHF, Nauni have revealed that the species is an annual herb with hollow stems and a taproot system. Seed procured from CIMAP, Lucknow has shown flowering and fruiting period of 14-18 days and 12-16 days, while seeds from UHF, Nauni, had flowering and fruiting period of 20-23 days and 16-19 days, respectively. Maximum plant height (106.51 cm), number of primary flower heads (4.50), number of secondary flower heads (2.75), number of seeds per plant (670), seed weight per plant (12.73g) and silymarin content (1.93%) were exhibited by the seeds from CIMAP, Lucknow. Sowing of seeds in the nursery during November under protected condition with application of vermicompost + cocopeat showed maximum germination (97.67%), shoot length (8.10 cm) and root length (7.43 cm). A spacing of 50 x 20 cm resulted in maximum plant height (135.40 cm), seed yield (13.35q ha-1), and silymarin content (2.19%) with the application of vermicompost + PSB. Maximum number of primary branches per plant (5.90), number of secondary branches per plant (3.41), number of primary flower heads per plant (5.90), number of secondary flower heads per plant (3.41), number of leaves per plant (18.84), number of seeds per primary capitulum (95.29), number of seeds per secondary capitulum (65.30), number of seeds per plant (1049.20), and seed weight per plant (17.88g) were obtained using vermicompost + PSB at a spacing of 60 x 40 cm. Highest output-input ratio (1.73) was noticed at 50 x 20 spacing with the application of PSB. The study showed that seeds sourced from CIMAP, Lucknow exhibited superior traits and nursery sowing in November under protected condition with the application of vermicompost + cocopeat was suitable for germination as well as seedling growth. Application of vermicompost + PSB at a spacing of 60 x 40 cm and 50 x 20 cm was best for growth and seed yield, respectively. The application of PSB at a spacing of 50 x 20 cm has greater economic feasibility.ThesisItem Open Access EFFECT OF CHEMICAL STIMULANTS ON OLEORESIN PRODUCTION AND WOOD QUALITY OF Pinus roxburghii Sargent(UHF,NAUNI, 2023-07-12) SAURABH SHARMA; BHUPENDER DUTTABSTRACT The present investigation entitled “Effect of chemical stimulants on oleoresin production and wood quality of Pinus roxburghii Sargent” was undertaken in the Department of Forest Products, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan-173230 (HP) during 2020-2022 with the objectives to find out the effect of chemical stimulants and methods of tapping on oleoresin production and quality, effect of chemical stimulants on wound healing of Borehole and Rill method and effect of methods of oleoresin tapping on the wood quality of Chir Pine respectively. Among the different chemical stimulants used for oleoresin tapping, treatment T7 (20 per cent H2SO4 + 20 per cent HNO3) showed best results for oleoresin yield. Healing rate in both Boreholes and Rill tapped blazes of Pinus roxburghii trees ranged from 4.64 (2.37) per cent to 96.25 (79.34) per cent. In contrast to traditional methods, where healing of these Boreholes and Rill tapped blazes takes at least 2-3 years and 20-30 years respectively, but by the application of new chemical stimulants, especially auxins like NAA (Napthalene Acetic Acid), rapidly healed the Boreholes and Rill tapped blazes within a year. Oleoresin tapping methods had significant effects on physical, chemical, and anatomical factors associated with wood quality. In order to improve oleoresin yield and wound healing, different chemical stimulants can be tailored and modified such as CEPA can be replaced with NAA, which can be used in combination with sulphuric acid which helps in prolonged resin flow. NAA is an auxin that aids in cell differentiation and growth leading to rapid healing of wounds caused by tapping, which could result in eco-friendly sustainable practices to ensure the long-term health and productivity of trees.ThesisItem Open Access STUDIES ON WOOD QUALITY CHARACTERISTICS OF MELIA SPECIES(UHF,NAUNI, 2023-05) SHUKLA, MOHIT; SOOD, MEENUABSTRACT The present investigations entitled “Studies on wood quality characteristics of Melia species.” were carried out in the Laboratory and Wood Workshop of Department of Forest Products, College of Forestry, Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during the years 2020-2021; 2021-2022 and 2022-2023.
