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 OF INDOOR PLANTS AND THEIR PERFORMANCE UNDER DIFFERENT ENVIRONMENTAL CONDITIONS
    (NAUNI,UHF, 2020-10) KUMAR, DINESH; BHATIA, SUMAN
    ABSTRACT The present investigation entitled “Assessment of air pollution tolerance index of indoor plants and their performance under different environmental conditions” was conducted during 2018-2019 in the Department of Floriculture and Landscape Architecture, Dr. Y.S Parmar University of Horticulture and Forestry, Nauni, H. P. In the first experiment, 30 flowering and foliage indoor plants were selected which are commonly grown in mid hills of H.P. and air pollution tolerance index was estimated in which various biochemical parameters such as total chlorophyll content, leaf extract pH, relative water content and ascorbic acid content were observed with 3 replications by using experimental design CRD. Maximum APTI value was found inAglaonema modestum (9.18), Scindapsus aureus (9.16), Chlorophytum comosum (9.14), Nephrolepis exaltata (9.054) and Kalanchoe blossfeldiana (8.967) and were assessed under different locations in experiment 2. These plants were kept in different locations such as office, bank, hospital, canteen and control (with in premises of this university) for 4 months and all plants were kept under iso-ecological situation. Different morphological, anatomical and biochemical parameters were observed under different locations by using factorial CRD experimental design. Regarding morphological parameters, maximum visual leaf colour grade was observed in the plants which were kept in office (4.769) as compare to other locations. Scindapsus aureus and Aglaonema modestum showed best visual colour grade under different environmental conditions. Anatomical parameters like number of stomata and stomatal index were found maximum in the plants which were kept in floriculture farm (36.08 and 16.45%, respectively) followed by office (34.40 and 15.93%, respectively). Regarding biochemical parameters like ascorbic acid (0.595 mg/g), relative water content (91.70%) and APTI (9.51) were found maximum in the selected indoor plants which were kept at canteen site. Whereas chlorophyll content (0.67 mg/g) and leaf pH (6.59) was recorded maximum in the plants which were kept in floriculture farm. The order of APTI in selected indoor plant species at different location was canteen/mess (9.51) > bank (9.11) > hospital (9.05) > office (9.04) control (8.93). High APTI value of selected indoor plants was observed in the plants which were kept at the canteen site. It was concluded that Aglaonema modestum, Scindapsus aureus, Chlorophytum comosum, Nephrolepis exaltata and Kalanchoe blossfeldiana were found best to tolerant air pollution on the basis of air pollution tolerance index (APTI). Further, Aglaonema modestum and Scindapsus aureus performed best under different environmental conditions and these plants can be used in indoor landscaping for urban areas.

    STUDIES ON INTENSITY, VARIABILITY AND EPIDEMIOLOGY OF CITRUS CANKER IN HIMACHAL PRADESH
    (COLLEGE OF HORTICULTURE AND FORESTRY, DR Y S P UHF, NERI, HAMIRPUR, 2019-10-22) KUMAR, DINESH; JARIAL, KUMUD
    The present investigations entitled “Studies on intensity, variability and epidemiology of citrus canker in Himachal Pradesh” was undertaken to record the occurrence of the disease, study physiological and epidemiological variability of pathogen and study the epidemiology of the disease. Citrus canker was prevalent on different Citrus spp. in moderate to severe form at various locations in three districts (Hamirpur, Kangra and Sirmour) surveyed in Himachal Pradesh. Disease incidence was found to be ranging between 40 to 100 per cent whereas, disease severity was found to be ranging between 2.78 to 50.55 per cent. Nine pathogen isolates were collected and purified and were identified as Xanthomonas axonopodis pv. citri on the basis of cultural characters and various biochemical tests. All the isolates tested positive both for protein digestion as well as esculin hydrolysis and gave negative reaction to Gram’s staining. Out of five different media tested, Wakimoto medium was found to the best medium for the growth of all isolates. Temperature of 25˚C and pH 7.0 was found to be optimum for the growth of all isolates. During pathogenicity test of all isolates under in vitro conditions on Kagzi lime as detached leaf assay, the incubation period and final symptom development was found to be ranging between 3.00 to 5.00 days and 14.00 to 16.00 days, respectively. All the nine isolates produced light yellow, yellow, pale, dark yellow, circular colonies with varied elevation and colony diameter ranging between 1.00 to 6.00mm on various solid media tested. Leaves of all age groups in nursery of K. lime were found to be susceptible towards the pathogen. Among different inoculation methods, pink prick method of inoculation was found to be best with shortest incubation period (4.18 days) under in vitro conditions. A temperature range of 25 to 35˚C and relative humidity more than 80 per cent was found to be optimum for symptom development under in vitro conditions exhibiting incubation periods between 2.00 to 5.00 days. All nine isolates exhibited considerable amount of variability in terms of various cultural and epidemiological traits under study. The periodical investigations of K. lime nursery at College of Horticulture and Forestry Neri, Hamirpur revealed that maximum disease incidence (88.45%) and disease severity (15.06%) was recorded during August, 2018 when the mean monthly temperature, relative humidity and cumulative rainfall were 26.54˚C, 76.43 per cent and 407.8 mm, respectively. Disease incidence as well as severity were found to be significantly and positively correlated with mean monthly temperature, average monthly relative humidity and cumulative monthly rainfall and these three factors were found to influence disease incidence and severity up to 91.16 and 79.94 per cent, respectively.
