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.

    STRUCTURE AND COMPOSITION OF WOODY ELEMENTS IN TIRTHAN AND SAINJ VALLEY OF GREAT HIMLAYAN NATIONAL PARK AT KULLU, HIMACHAL PRADESH
    (UHF,NAUNI, 2019-07) MOHAPATRA, SOURAV RANJAN; SANKHYAN, H P
    ABSTRACT The present investigation entitled Structure and Composition of woody elements in Tirthan and Sainj valley of Great Himalayan National Park at Kullu, Himachal Pradesh” was carried out in three different elevation i.e. Lower zone (1500-2000 m.), Mid zone (2000-2500 m.) and Upper zone (2500-3000 m.) of Tirthan and Sainj valley separately in Great Himalayan National Park. In every elevational zone, 12 quadrats of 10 m X 10 m (100 sq m) size determined by species area curve method were randomly laid to study tree species. In each quadrat, a sub-quadrat of 5m X 5m (25 sq m) size for study of shrubs and sub-quadrat of 2 x 2 m (4 sq m) to record natural regeneration was selected. The generic spectrum of vegetation in Tirthan and Sainj valley of Great Himalayan National Park comprised of 156 woody elements which included 58 tree species and 98 shrub species. Tirthan valley was comprised of 113 woody elements where as in Sainj valley total of 95 woody elements were reported, hence in terms of floral composition Tirthan valley was rich. In both Tirthan and Sainj valley, number of forest species decreased periodically from lower elevation to upper elevation. Tree density (Individual/ha.) in Tirthan valley was 683.33, 758.34 and 816.67 for lower zone, mid zone and upper zone respectively. Likewise in Sainj valley it was 716.67 for lower zone, 791.67 for mid zone and 836.67 for upper zone. In Tirthan mean density of tree vegetation increased along elevation, Similar results in the forest of Sainj valley also. The shrub density (Individual/ha.) in Tirthan was 2866.67, 1900, 2866.67 for lower, mid and upper zone respectively while in Sainj it was 2400 for lower, 1766.67 for mid and 1133,33 for upper zone of the valley. In both the valleys of GHNP shrub vegetation decreased along the elevation. In both the case of tree and shrub vegetation, density was correlated with avg. basal area. In Tirthan valley, Pinus wallichiana at lower zone (IVI 58.7), Picea smithiana at mid zone (IVI 50.43), Quercus semecarpifolia at upper zone (IVI 70.79) were the dominant tree species. Likewise in Sainj valley dominant tree species at lower zone was Cedrus deodara (IVI 64.62), at mid zone was Abies Pindrow (IVI 65.39) while at upper zone was Quercus semecarpifolia with IVI 81.41. In shrub layer of Tirthan forest, dominant species at lower zone was Desmodium triflorum, at mid zone was Indigofera heterantha while at upper zone it was Rosa sericea. In Sainj valley Rubus ellipticus, Sorbaria tomentosa and Rosa sericea were the dominant shrub species at lower, mid and upper elevations respectively. In case of both trees and shrubs vegetation, Sorenson’s and Jaccard’s indices of similarity showed maximum per cent of similarity in same altitudinal ranges. Most of the tree and shrub species were characterized by contagious type of distribution while random and regular patterns were recorded for few species only present at different altitudinal ranges of Tirthan and Sainj valley. Natural regeneration at different elevation of Tirthan and Sainj valley revealed, Maximum regeneration success at mid altitudinal range among all the three elevations. The primary data for DBH of trees present at different elevational zone of Tirthan and Sainj valley was subjected 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 lower elevation of both the valleys, weibull was best fitted for mid and upper elevation of Tirthan valley while, normal and lognormal were best fitted for mid and upper zone of Sainj valley respectively to estimate the number of trees in various diameter classe

    SEED SOURCE STUDIES IN WILD POMEGRANATE (Punica granatum L.) IN HIMACHAL PRADESH
    (UHF, NAUNI, 2019-01) NEGI, ANMOL; GUPTA, TARA
    ABSTRACT The present investigations entitled “Seed Source Studies in Wild Pomegranate (Punica granatum L.) in Himachal Pradesh” was carried out in the Department of Tree improvement and Genetic Resources, Dr. Y.S. Parmar University of Horticulture and Forestry Nauni, Solan (HP) during 2017-2018 with the aim to evaluate the seed sources on the basis of phenotypic characters, morphometric characters, seed traits, fruit characteristics and nursery stage growth performance of the half sibs. Present study was conducted by selecting five trees each of the ten seed sources namely Narag (S1) and Neripul (S2) district Sirmour, Waknaghat (S3) and Sadhupul (S4) district Solan, Basantpur (S5) district Shimla, Sundernagar (S6), Rewalsor (S7) and Aut (S8) district Mandi, Mohal (S9) and Banjar (S10) district Kullu. Phenotypic studies revealed that Neripul (Sirmour) seed source had higher phenotypic values as compared to other seed sources. Leaf morpholological and morphometric characteristics were maximum in Sadhupul (Solan) with higher leaf area value of 12.66 cm2 and Mohal (Kullu) with maximum leaf petiole 0.5 cm which was significantly higher than other seed sources. Sundernagar (Mandi) seed source have shown highest (70.46 %) germination percentage followed by Basantpur (Shimla) with the value of 67.71 %. Fruit characteristics were found better from Banjar (Kullu) seed source because of larger fruit size having the average fruit length and breadth of 38.83 mm and 39.53 mm respectively. The biochemical analysis for fruit pulp revealed that Sundernagar seed source was best for TSS and sugars followed by Rewalsor, Banjar and Basantpur seed sources. For nursery stage growth performance seedlings height was found maximum (56.63 cm) in Waknaghat (Solan) seed source followed by Sundernagar which is significantly lower values (56.00 cm) for height. Among all the half sibs Banjar (Kullu) seed source had minimum seedling height. Important traits like 100 dry seed weight was found maximum in Neripul (Sirmour) with the value of 3.53 g which was highest among other seed sources. High heritability and genetic gain was found in seedling height (0.9, 64.82 %), tree height (0.98, 42.08 %), seed germination (41.64 % genetic gain), fresh fruit weight (0.35, 26.65 %). The findings of the study on fruit quality, seed traits and seedling performance indicate that significant gains can be achieved through selections at seed source level but individual tree selections can be exercised for fruit characters as a basis of the tree improvement and breeding program of wild pomegranate.
