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.

    PRODUCTIVITY AND CARBON STORAGE IN PREVALENT AGROFORESTRY SYSTEMS IN SUB TROPICAL REGION OF HIMACHAL PRADESH

    ABSTRACT Agroforestry is a comprehensive technology towards stable exploitation from the field which is created by means of combining trees, pasture and agricultural crops in a certain area and by applying special management practices. Performing these methods of exploitation from the land is more effective in the sequestration of atmospheric carbon. Carbon dioxide is one of the major greenhouse gas that increased due to combustion of fossil fuels, deforestation etc, are the most important factors for global climate change. Land use system such as agroforestry plays an important role in climate change mitigation by absorbing excess carbon dioxide which is used in the process of photosynthesis by the trees. Hence, the present investigation was carried out to study the Productivity and carbon storage in prevalent agroforestry systems in sub tropical region of Himachal Pradesh. Bilaspur and Hamirpur districts were selected for the study, in each district three altitudinal zones were prepared, such as altitudinal zone I (400-600 m asl), zone II (600-800m asl), zone III (800-1000m asl) and in each altitudinal zone, four farmers category were made namely, marginal (<1 ha), small (1-2 ha), medium (2-4 ha) and large(>4ha). Finally from each farmer category 10 farming families were taken for the study. The plot size 50×10 m for trees, 1×1 m for agricultural crops and for grass 0.5×0.5 m were used for identification of agroforestry systems, biomass, carbon stock and estimation of economic productivity. The results found that prevalent agroforestry systems in subtropical region of Himachal Pradesh were AS, ASH, AH, AHS, PS, PSH, PHS and PH. Among these system types most predominant were PS followed by PSH, AS and ASH systems. The maximum above ground biomass production in three altitudinal zones was noticed in AHS with zone II (45.32 t ha-1) while in four farmers category was maximum in AHS with small farmers (45.33 t ha-1). Higher Above ground biomass production of pastoral agroforestry systems among three altitudinal zone was observed in PSH with zone II (28.90 t ha-1) whereas, in four farmers category was recorded maximum in PHS and medium farmers (28.67 t ha-1). Maximum above ground carbon stock in three altitudinal zones was found in AHS with zone II (20.39 t ha-1) whereas, among four farmers category was noticed maximum in AHS and small farmers (20.40 t ha-1) while in pastoral agroforestry systems was higher above ground carbon stock was observed in PSH and zone II (13.0 t ha-1) whereas, among four farmers category was found highest in PHS with Medium farmers (12.90 t ha-1). Maximum total ecosystem carbon stock among the three altitudinal zones was indicated in AH and zone III (58.39 t ha-1) whereas, among four farmers category was recorded higher in AH with large farmers (64.44 t ha-1). On the other hand maximum total ecosystem carbon stock of pastoral agroforestry systems at three altitude was observed in PSH and zone II (40.55 t ha-1), while four farmers category was found maximum in PSH and medium farmers (44.19 t ha-1). Maximum net returns among three altitudinal zones was reported in AHS with zone II (Rs. 178641), while four farmers category was recorded maximum in AHS and small farmers (Rs. 163353). In pastoral agroforestry systems highest net profit among three altitudinal zones was noticed in PSH and zone II (Rs. 86145), on the other hand in four farmers category was recorded higher net profit in PSH and medium farmers (Rs. 90809). Benefit: cost ratio of agroforestry systems among three altitudinal zones was noticed highest in AH with zone I (2.74) while in four farmers category was recorded maximum in AHS and small farmers (2.77). Pastoral agroforestry systems was observed highest B: C ratio in PHS and zone I (2.17) on the other hand among four farmers category was found maximum in PHS and small farmers (2.47). From the above study it is concluded that ASH and AHS system type found to be best for carbon storage and economic point of view respectively, hence these systems may be recommended to the subtropical region of Himachal Pradesh.
