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.

    FLORISTIC COMPOSITION, CARBON DENSITY AND NUTRIENT STATUS UNDER NATURAL AND PLANTATION FOREST ECOSYSTEMS IN MID HILL CONDITIONS OF HIMACHAL PRADESH

    ABSTRACT The present investigations entitled “Floristic composition, carbon density and nutrient status under natural and plantation forest ecosystems in mid hill conditions of Himachal Pradesh” were carried out through independent experiments at different forest ecosystems of Kunihar forest division, Solan district, HP which lied between 76º40′35″ to 76º55′10″ E longitude and 30º53′15″ to 31º14′25″ N latitude 300-2100 a.m.s.l. The present investigations were conducted to assess the status of floristic composition, biomass, carbon storage, nutrient status and soil microbial properties under different ecosystems of Kunihar Forest Division. The results revealed that the selected forest ecosystems of the study site comprised of 141 plant species, including 34 tree species, 30 shrub species, and 77 herb species from 102 genera and 44 families. In the presents study tree density was recorded range from 16 (Sub tropical euphorbia scrub forest)-1445.33 N ha-1 (Dry bamboo brakes) and basal area ranged from 0.26 (Sub tropical euphorbia scrub forest)- 69.52 m2 ha-1 (Shiwalik chir pine forest) across the study sites. The shrubs density and basal area ranged from 1950-13150 N ha-1 and 1.19-44.18 m2 ha-1 attaining maximum shrub density in Northern dry mixed deciduous forests and minimum in Chir pine plantation. The shrubs density and basal area ranged from 1950-13150 N ha-1 and 1.19-44.18 m2 ha-1 attaining maximum shrub density in Northern dry mixed deciduous forests and minimum in Chir pine plantation. The results of the experiment have revealed that maximum vegetation biomass, vegetation carbon density and ecosystem carbon density was recorded in Lower Western Himalayan Ban-Oak forest with value of 456.52 Mg ha-1, 228.26 Mg C ha-1 and 382.07 Mg C ha-1, respectively. Shiwalik chir pine forest had the highest nitrogen concentration (13226.33 kg ha-1). Lower Western Himalayan Ban-Oak had the highest phosphorus concentration (2989.19 kg ha-1). The highest potassium concentration (5335.87 kg ha-1) was found in the Leucaena leucocephala plantation. Lower Western Himalayan Ban-Oak had the highest calcium content (37499 kg ha-1). Soil organic carbon (2.35%), available nitrogen (519.44 kg ha-1), available potassium (575.01 kg ha-1) and exchangeable calcium were highest in the northern dry mixed deciduous forest (1683.82 mg kg-1). Whereas Lower Western Himalayan Ban-Oak had the highest available phosphorus (23.31 kg ha-1) and CEC (17.38 mg kg-1) and Natural grasslands had the highest exchangeable magnesium (934.68 mg kg-1). The highest bulk density (1.49 g cm-3) and soil pH (7.17) was found in Natural grasslands. The maximum soil EC (0.22 dsm-1) was recorded under Dry bamboo brakes. Lower Western Himalayan Ban-Oak (T7) showed significantly faster rate of surface litter decomposition in comparison with other forest ecosystems. Northern dry mixed deciduous forest had the highest soil microbial activity (0.26 CO2 evolution g-1 soil), microbial biomass (1094.49 μg g-1 soil) and bacterial count (195.21 x105 cfc g-1 soil). This study concluded that the Lower Western Himalayan Ban-Oak forest has greater potential for carbon density and can add nutrient rapidly to the soil through litter decomposition as compared to other forest ecosystem. Among the plantation ecosystem Leucaena leucocephala plantation can sequester more carbon than other plantation ecosystem and such plantation should encourage for climate change mitigation strategies. Lantana camara is heavily infested in this forest division so proper management practices should be taken up to eradicate this invasive spp. Based on findings of the study assessing the biomass and carbon density is recommended to prioritize tree species-specific land use practices, and to ensure climate change mitigation.
