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.

    EFFECT OF INORGANIC, ORGANIC AND NATURAL SYSTEMS OF NUTRIENT MANAGEMENT IN FRUITS AND THEIR IMPACT ON SOIL PROPERTIES
    (UHF,NAUNI, 2023-09-27) SAURABH SHARMA; UDAY SHARMA
    ABSTRACT The studies, “Effect of inorganic, organic and natural systems of nutrient management in fruits and their impact on soil properties” were conducted during 2021 and 2022. Four orchards each under inorganic, organic and natural systems of nutrient management in mango, apricot and apple growing in Bilaspur, Solan and Shimla districts respectively, were selected. The inorganic system recorded the highest available N, P, K, exchangeable Ca, Mg , S, DTPA extractable Zn, Fe, Mn and Cu (349.6, 64.0, 376.5 10.07 cmol (p+) kg-1, 4.19 cmol (p+) kg-1, 43.18 kg ha-1, 3.17, 25.8, 13.2 and 2.59 mg kg-1, respectively. Sub- surface soils followed the similar trend. In all parameters apple, due to better management registered higher values for all nutrients. The highest OC (18.40 g kg-1 and 13.23 g kg-1 in 0-20 and 20-40 cm depths, respectively). and soil microbial biomass carbon (269.4 μg g-1 soil), and other microbial properties were recorded under natural farming system. Among the plant parameters the maximum levels of nutrients in the leaves (2.55 % N, 0.25 % P, 1.66 % K, 2.17 % Ca, 0.69 % Mg, 232.7 ppm Fe, 10.2 ppm Cu, 28.6 ppm Zn and 64.1 ppm Mn) were recorded under inorganic nutrient management. The plant growth parameters were noted best under inorganic nutrient management. The soil quality index was highest with inorganic nutrient management system with index value of (0.60, 0.59 and 0.57) for apple, mango and apricot, respectively. The pot culture studies show that the treatment (T1) i.e., RDF + FYM recorded the maximum change (increase) in the physico-chemical properties soil of orchards, while the percent increase in microbiological properties was recorded highest with the treatment T2 i.e. NPK equivalent through FYM. Thus inorganic nutrient management along with FYM results in the maximum soil and leaf nutrient levels which directly affects the growth, flowering, fruit yield and quality of apple, mango and apricot. However, the natural farming system has shown promise and the soil quality parameters in the organic and natural systems of nutrient management emphasize their adoption for niche areas in order to get premium pricing and long-term sustainability.

    EFFECT OF CHEMICAL STIMULANTS ON OLEORESIN PRODUCTION AND WOOD QUALITY OF Pinus roxburghii Sargent
    (UHF,NAUNI, 2023-07-12) SAURABH SHARMA; BHUPENDER DUTT
    ABSTRACT 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.
