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.

    STUDIES ON WOOD CHARACTERISTICS USING Parthenium hysterophorus L. EXTRACT AS A WOOD BIOPRESERVATIVE
    (2013) LALIT, KUMAR; DUTT, BHUPENDER
    ABSTRACT The present investigations entitled “Studies on wood characteristics using Parthenium hysterophorus L. extract as a wood biopreservative” was carried out in the Department of Forest Products, Nauni, Solan (H.P.) Products and also in the Laboratory of Fruit Pathology in the Department of Mycology and Plant Pathology, Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP). Wood samples of Pinus roxburghii Sargent, Celtis australis L., and Bombax ceiba L. of size 5cm x 2.5cm x 2.5cm ( longitudinally x radially x tangentially ) were taken for the study. The wood specimens of Pinus roxburghii Sargent, Celtis australis L., and Bombax ceiba L. were dipped in 0.00%, 0.25%, 0.5%, 1%, 1.5% and 2 % (w/v ) Parthenium hysterophorus L. extract solution for 72 hours. These were analysed for variation of specific gravity, per cent weight gain of treated and untreated wood on dry weight basis, per cent weight gain of treated and untreated wood on wet weight basis, weight gain, volumetric swelling coefficient, volumetric shrinkage coefficient, Swelling and shrinkage of wood in three different planes, chromium absorption, chromium leaching, chromium retention, per cent fungal growth and per cent fungal inhibition. The maximum value of specific gravity was recorded in Celtis australis L. (0.576) and minimum in Bombax ceiba L. (0.432) showing significant difference.Swelling and shrinkage of wood were recorded maximum for Pinus roxburghii Sargent in all the planes viz.,longitudinal, radial and tangential plane. Maximum volumetric swelling coefficient was recorded for Pinus roxburghii Sargent wood at 1.5% concentration and minimum for Celtis australis L. at 0.25% concentration.The volumetric shrinkage coefficient was recorded highest for Pinus roxburghii Sargent in control and lowest for Bombax ceiba L. at 1.5% concentration. The maximum per cent variation in weight of treated and untreated wood on dry and wet weight basis had been recorded in Bombax ceiba L. wood in control and minimum in Pinus roxburghii Sargent at 0.25% and Celtis australis L. at 0.5% concentration. The mean values of oven dry weight for different treatments increased with the increase in concentration upto 1.5% at par with 2% concentration. The highest value was recorded in Bombax ceiba L. at 2% concentration and the lowest in Bombax ceiba L. in control. Maximum value for chromium absorption, chromium leaching and chromium retention found at 10% chromic acid concentration and minimum at 5% chromic acid concentration. Maximum fungus colonization were recorded in control (100%) for all the species and Pinus roxburghii Sargent at 0.25% concentration. The minimum fungus colonization in Bombax ceiba L. was found at 2% concentrations (48.38%). Highest fungus growth inhibition was recorded for Bombax ceiba L. at 0.25% concentration (7.25 %) and the lowest for control in all the species and for Pinus roxburghii Sargent at 0.25% concentrations.

    EVALUATION OF SOME ESSENTIAL OILS AGAINST PULSE BEETLE ( Callosobruchus chinensis L . ) IN PEA SEEDS
    (2015) LALIT, KUMAR; VERMA, SUBHASH CHANDER
    ABSTRACT The present investigations on “Evaluation of some essentials oils against pulse beetle (Callosobruchus chinensis L.) in pea seeds” were carried out during 2014-15 in the Department of Seed Science and Technology, College of Horticulture, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni–solan (H.P). The essentials oils of camphor, wild marigold, cone-bearing sage, eucalypts, lemongrass and sweet flag at 2.5 ml/kg, 1.25 ml/kg , 0.60 ml/kg and 0.30 ml /kg (v/w basis)were evaluated against C. chinensis L. infesting pea seeds. Among the six essentials oils, sweet flag possessed reasonably high and immediate toxicity irrespective of its doses. It resulted in 78.33 percent overall mortality with in a day of treatment, while in 3 days mortality increased to 96.67 percent (2.5 ml/kg and 1.25 ml/kg doses resulted 100 % mortality). After 7 days cent per cent mortality was observed in seeds coated with sweet flag essential oil followed by eucalypts (85.83%) cone - bearing sage (77.50%), camphor (74.17%), lemongrass (71.66%) and wild marigold (61.67%) in decending order. After 10- days of exposure, eucalypts essential oil also resulted complete kill even at lowest dose (0.30ml/kg). On day -15, mortality in control had substantially increased to 67.50 percent. Egg laying was minimum on sweet flag essential oil treated pea seeds (5.25 eggs/5 females) on 7th – day of observations. In untreated pea seeds, increases in egg laying was negligible in 20 – days observations (7th day 94.08- 20th day 101.92). Progeny development from the eggs laid on pea seed traeated with sweet flag essentials oil was (1 beetle). Maximum protection to treated pea seed in terms of reductions in seed damage by C. chinensis was provided by sweet flag essential oil (0.33%) and lemongrass essential oil (3.90%). Next effective treatments were wild marigold (6.81%), camphor (7.86%), cone - bearing sage (7.94%) and eucalypts (11.74%). Pea seeds treated with sweet flag essential oil resulted 92.75 per cent germination followed by lemongrass essential oil (85.58%), camphor (78.33%), cone – bearing sage (43.75%), eucalypts (41.25%) and wild marigold (39.42%). Sweet flag essential oil resulted 1665.19 seed vigour index – I followed by lemongrass essential oil (1440.78), camphor (1193.76) eucalypts (843.69), cone - bearing sage (714.09) and wild marigold (685.30). Maximum seed vigour index –II was recorded in sweet flag essential oil (2115.74) treated pea seeds followed by lemongrass (1681.86), camphor (1524.56), cone -bearing sage (1153.46), eucalypts (1097.59) and wild marigold (799.55). In case of essential oils as grain protectants sweet flag essential oil at 2.5 ml/kg was effective in protecting pea seeds up to 8 months. After 2 months pea seeds treated with sweet flag essential oil resulted 91.11 per cent pulse beetle mortality followed by camphor (42.22%), eucalypts (35.56), lemongrass (33.33%), wild marigold (31.11%) and cone-bearing sage (28.89%). After month-4 mortality recorded in sweet flag essential oil treated pea seeds were significantly high (71.11%) as compared to other treatments. After month 6 only sweet flag essential oil was effective. Minimum egg laying (10 eggs/5 females) was recorded in pea seeds treated with sweet flag essential oil after 2-months of treatment. Pea seeds treated with sweet flag essential oil at 0.30 ml/ kg resulted adult emergence of 2.67 beetles, seed damage (0.70%), weight loss (0.23%) and highest germination (91.33%), seed vigour index-I (1360.65) and seed vigour index-II (1800.32). Mixing of pea seeds with sweet flag essential oil at 0.30 ml/kg provided protection up to 2-months of treatment whereas pea seed treated with 2.5 ml/kg would be effective in protecting pea seed against damage caused by pulse beetle, Callosobruchus chinensis L. up to month -8 of treatment.
