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.

    EVALUATION OF AIR POLLUTION TOLERANT TREES GROWING IN SOLAN CITY OF HIMACHAL PRADESH
    (UHF,NAUNI, 2014) SHARMA, AKANKSHA; BHARDWAJ, S.K.
    ABSTRACT The present investigation entitled “Evaluation of air pollution tolerant trees growing in Solan city of Himachal Pradesh” was conducted during 2013-2014 in Solan city of Himachal Pradesh. In order to study the vegetation distribution as well as to select the site survey of the city was conducted. Based on the survey five sites were selected as: i) control ii) residential iii) traffic iv) industrial v) periurban. In order to select non – polluted site as a control, the nearby forest / agriculture field areas surrounding the city, where in relatively less development activity has taken place. Three tree species namely: Ficus palmata, Pistacia integerrima and Polpulus deltoides of uniform age, size, spread and common in occurrence in all the five sites in the city were selected for the study. In order to study tolerance and sensitivity of trees to air pollution, Air Pollution Tolerance Index (APTI) was computed based on physiological and biochemical parameters (ascorbic acid, chlorophyll, pH and relative water content). Dust accumulation on the leaves was recorded during rainy, winter and summer season. The leaf dust load was also analyzed for heavy metal content. In total there were 45 treatment combinations which were replicated four times in Randomised Block Design (Factorial). The APTI of selected trees ranged from 9.45- 13.49. T he order of tolerance of selected tree species was Ficus palmata (12.31) > Populus deltoides(11.76) > Pistacia integerrima (10.45) . The highest APTI was noticed in rainy followed by winter and summer season. The trend of APTI for tees growing at different sites was traffic >industrial > residential >peri - urban > control. The relatively higher APTI value of Ficus palmta as compared to other species indicated its tolerance to pollution in Solan city. The dust accumulation on the leaves of selected tree species growing at different sites in Solan city was found maximum 0.041 g m -2 in Ficus palmata and minimum 0.005 g m -2 in Populus deltoides, which followed the order of Ficus palmata> Pistacia integerrima>Polpulus deltoides and season wise maximum in winter followed by summer and minimum in rainy season. Trees grown at traffic area accumulated higher dust on their leaves as compared to control area (non-polluted). The dust load of all the species growing at different sites in Solan city contained significan t concentration of heavy metals like Cd (0.132 – 1.862) , Hg (0.007 - 7.216) , Pb (2.903 - 9.231) , Zn (0.783 - 3.708) , Ni(20.50 - 99.19) and Mn(12.06 - 16.32) . The concentration of Cd (1.862 mg kg - 1 ) and Hg (7.216 mg kg - 1 ) in leaf dust load of selected tree species was above the normal permissible limit prescribed for soil .
