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.

    ASSESSMENT OF AIR POLLUTION TOLERANCE INDEX OF CERTAIN PLANTS GROWN ALONGSIDE PARWANOO- SOLAN NATIONAL HIGHWAY OF HIMACHAL PRADESH
    (2012) KALER, NAVJOT SINGH; BHARDWAJ, S.K.
    ABSTRACT The present investigation entitled “Assessment of air pollution tolerance index of certain plants grown alongside Parwanoo-Solan National Highway of Himachal Pradesh” was conducted during 2011-2012 on Parwanoo to Solan National Highway falling in Solan district of Himachal Pradesh. The Four species namely Grewia optiva, Toona ciliata, Melia azedarach and Woodfordia floribunda of uniform size, age, spread and common in occurrence on both sides of the highway were selected for the study. Dust accumulation and biochemical parameters (pH of leaf extract, relative water content, ascorbic acid content and chlorophyll content) of leaves of selected plants was estimated during three main seasons (Rainy, Winter and Summer) of the year. Air pollution tolerance Index (APTI) of selected species was worked out. The heavy metal concentration on deposited dust was also determined. Samples were collected from two horizontal distances (0-5 m and 5-10 m) on the both sides of road during study. In total there were 24 treatment combinations which were replicated six times in Randomised Block Design (Factorial). The dust accumulation on the leaves ranged from 0.0083 g m-2 in T. ciliata to 0.0597 g m-2 in G. optiva which followed the order of G. optiva > W. floribunda > M. azedarach > T. ciliata. Irrespective of species, season wise trend of species was winter > summer > rainy season. Plants grown at a distance of 0-5 m accumulated higher dust on their leaves as compared to 5-10 m distance from the road. The highest pH was recorded in M. azedarach (7.66) and lowest in W. floribunda (5.85) and the pH was maximum in rainy followed by winter and summer season. Leaf relative water content was maximum in M. azedarach (59.34 %) and minimum in T. ciliata (49.76 %) and season wise, it was highest in rainy followed by winter and summer season. The highest ascorbic acid content was recorded in M. azedarach (8.40 mg g-1) and lowest in T. ciliata (2.13 mg g-1). Ascorbic acid content was recorded maximum in winter followed by summer and rainy seasons. Highest chlorophyll content was found in M. azedarach (7.18 mg g-1) and lowest in T. ciliata (2.18 mg g-1) and was recorded highest in rainy followed by winter and summer season. The APTI was found maximum in M. azedarach (18.37) and minimum in T. ciliata (6.82). The APTI also varied with seasons of the year. The highest APTI was noticed in rainy followed by winter and summer season. The trend of APTI recorded for various species was M. azedarch > G. optiva > W. floribunda > T. ciliata. The present study indicated M. azedarach as most tolerant and T. ciliata as most sensitive species to air pollution. The dust accumulated on leaves had heavy metals, Cu (29.14 mg kg-1) and Zn (1219.91 mg kg-1) above permissible limit of the soil
