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 canopy distribution, stand growth and regeneration in Cedrus deodara (Roxb.) Loud under temperate conditions of Himachal Pradesh
    (YSPU, 2016) Prahlad, V.C.; Gupta, N.K.
    Current investigation entitled “Studies on canopy distribution, stand growth and regeneration in Cedrus deodara(Roxb.) Loud under temperate conditions of Himachal Pradesh” was undertaken in the year 2011-13 in selected natural pure stands. The study intended to assess the growth and natural regeneration characteristics under different locations and age groups in relation to light pattern andsite quality. The stand structure study conducted at bole and canopy level for vital stand parameters through standard forest measurement technique on sampling base in four Periodic blocks (PBI, PBII, PBIII and PBIV) in three sites Habban, Chail and Cheog with three replications. Radiation study conducted beneath the canopy through capturing hemispherical images using CI-110 digitalplant canopy analyser. The site quality assessmentwas carried out plotting age and quality height curves of yield table against site height curves to denotebase years. Important statistical tools were employed to adjudge their significance. Subsequently results showed 943.33 to 203.33 stems/ha at Chail PBIV and Habban PBI. The stocking level was found irregular and clumped at middle age with missing stems in both lower and higher diameter classes. Cheog showed highest mean diameter (40.34 cm), height (26.67 m), stem volume (481.39 m3/ha). But, Chail showed good performance with stem density, mean basal area (m2/ha) and vital crown parameters in general. Attainment of maximum mean tree height at S3 (26.67 m) and in PBI (31.88 m) was attributed to good site quality and competitive vigor. The correlation study and regression study indicated strong correlation between diameter with height, crown width,volume and crown width with crown areas Further, crown width showed higher correlation coefficient with crown areas (surface and basal), crown projection ratio, crown volume and stem volume in general for all sites and PBs. The transmission coefficient or gap fraction values showed maximum 0.609 and minimum 0.46 this eastvariation might be the result of uniformity in canopy conditions as a result of present silvicultural management practices. The quantitative characterization of site quality, highest growing stock, highest crop height performance and highest LAI indicated the superior site quality for Cheog over others. Chail and Cheog indicated availability of large numbers of recruitsthan Habban due to low surface litter, low soil emperature and favorable PAR. The un-established seedlings/ha were maximum and minimum with values 8833.33 and 166.67 recorded at Cheog (PBIV) and Chail (PBI). The established individuals/ha at Chail PBIV showed highest (6333.33) and lowest values (500) at both Cheog (PBI and PBIII). The stablished stocking percent was highest at PBIV in all the sites with decreasing trend from PBIV toPB I. However, regeneration success as well as established stocking percent (more than 100%) found in all the regeneration PBs.

    Site characteristics and regeneration studies of bani oak (Quercus glauca Thunberg) in Himachal Pradesh
    (YSPU, 2016) Tesfaye, Amare; Bhardwaj, D.R.
    The study was carried out at Quercus glauca bearing forests of Solan, Nareg and Sarhan forest ranges of Himachal Pradesh, India during the year 2013-2015. Six forest sites viz.: Solan,Oachghat, Deothal, Narag, Chakla and Tikri were non randomly selected to assess effects of phytosociology, stand characteristics and site conditions in natural regeneration of the species as well as effects of stratification media, stratification duration, acorn size and pre-sowing treatments on germination and growth characteristics Quercus glauca seedlings. Data collection, analysis and interpretation were conducted based on standard field, laboratory and statistical procedures. Stand structure, species composition, site characteristics and status of natural regeneration varied a lot in the study sites. Natural regeneration of Quercus glauca was better at Oachghat and Narag forest sites, in which major tree associates were Machilus duthiei, Dalbergia sissoo, Bauhinia variegate, Pinus roxburghii, Pyrus pashia and Myrica esculenta. Natural regeneration of Quercus glauca was positively related to soil moisture content, organic carbon and organic matter layer and it was negatively related to soil pH and solar influx. In general, natural regeneration increased with increase in tree density but it decreased with increase in shrub and herb density. In the stratification trial, highest germination of acorns were recorded under farmyard manure media (51.8 %) and 45 days stratification duration (49.5%). Shaded growing conditions had been found better in germination, survival and seedling growth characteristics than open nursery conditions. Germination was higher in nutrient rich stratification media. Total sugar content was increasing, whereas, starch and soluble protein content of acorns was decreasing with increase in germination. Application of 100 ppm GA3 treatment and exposed embryo had higher germination for chemical and physical pre-sowing treatments under laboratory conditions, respectively. Physical pre-sowing treatments had also better performance in germination than chemical pre-sowing treatments. The study concluded that maintaining tree density and plant associates that enhanced natural regeneration of Quercus glauca should be preserved for the sustenance of the species. The use physical pre-sowing treatments in combination of shaded growing conditions should be encouraged for artificial reproduction of the species.
