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.

    STATISTICAL INVESTIGATIONS ON CONIFERS OF TEMPERATE ZONE IN HIMACHAL PRADESH
    (UHF,NAUNI, 2017-10) SHARMA, AJIT; GUPTA, R.K.
    ABSTRACT The present investigation entitled “Statistical investigations on conifers of temperate zone in Himachal Pradesh” was carried out in the forest area of Himachal Pradesh. For the study, primary data for diameter and height of conifer plantations was collected from three different forest circles viz. Kullu, Shimla, and Kinnaur. 300 trees of five conifer species viz. Cedrus deodara, Pinus roxburghii, Pinus wallichiana, Abies pindrow and Picea smithiana were recorded from each forest circle and volume was collected from the State Forest Department. The data were subjected to variability analysis in order to test the variability among different circles. Bartlett's chi-square test was used for testing the homogeneity of variances with respect to diameter, height and volume. Various probability distributions were fitted to find out the expected number of trees in each diameter class and its significance was tested by using Kolmogorov-Smirnov test statistic. Gamma distribution was observed best fitted for Cedrus deodara, Pinus wallichiana and Picea smithiana, while normal and log-normal distributions were best fitted for Abies pindrow and Pinus roxburghii respectively to estimate the number of trees in various diameter classes in temperate zone. Regression analysis was done to estimate the volume of conifer species for the construction and prediction of one way volume tables and two way volume tables on the basis of maximum value of R and R , minimum RMSE and Theil’s U-statistic, whereas validation was tested by half-split method and Chow test. The best fit linear model for Cedrus deodara and Pinus wallichiana moreover non-linear power model for Pinus roxburghii, Abies pindrow and Picea smithiana was used to construct two way volume tables. The relative dominance of conifer species was tested out with the help of importance value index (IVI).
