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.

    Ecological and Economical Appraisal of Apple based Agroforestry Systems in Kullu Valley of Himachal Pradesh
    (College of Horticulture and Forestry Neri, Hamirpur (H.P.), 2022-12-23) Acharya, Manvi; Sharma, Kamal
    The study entitled “Ecological and Economical Appraisal of Apple based Agroforestry Systems in Kullu Valley of Himachal Pradesh” was carried out in apple orchard of Bhindi Bai Village, Bajaura, Kullu. The experiment was laid out in Randomized Block Design, having nine treatments (sole apple, sole tomato, sole brinjal, sole capsicum, sole black gram, apple + tomato, apple + brinjal, apple + capsicum and apple + black gram) with three replications in order to assess the biomass, carbon stock, soil physico-bio-chemical properties and to work out economics of the various tree-crop combinations while for comparing growth and yield parameters of agricultural crops grown under agroforestry and sole cropping, Student ‘t’ test was employed. The studies revealed that apple competed with agricultural crops (brinjal, capsicum and black gram) for moisture, nutrients and other limiting resources which resulted in poor performance (growth and yield) of agricultural crops except for tomato which performed better as an intercrop. Among all tree + crop combinations, the highest total biomass (44.05 t/ ha) and total carbon stock (21.73 t /ha) were recorded under apple + tomato. From economics point of view, the maximum (991971 Rs/ha) gross returns, net returns (566900.96 Rs/ha) and benefit-cost ratio (2.33) were obtained for apple + tomato. Among all the physicochemical properties, bulk density, particle density, soil porosity, pH and organic carbon were found to be affected significantly while, the soil moisture remained unaffected. Results also indicated that with increase in soil depth from 0-15 cm to 15-30 cm, particle density, bulk density and pH increased whereas, reverse trend was observed for porosity, EC, soil moisture and soil organic carbon. The available N, P and K contents decreased with the increase in soil depth under all treatments. Among all treatments, the maximum nitrogen and potassium contents were observed under apple + black gram while, the maximum phosphorus was recorded under apple + brinjal. Microbial biomass and annual flux of C, N and P were recorded the highest under apple + tomato agroforestry system at both soil depths. However, microbial biomass and flux decreased with the increase in soil depth. The soil enzymatic activities viz., dehydrogenase, catalase, acid and alkaline phosphatase were also observed highest under apple + tomato.The improvement in soil physico-chemical properties indicated that the selected tree-crop combinations are sustainable.Agroforestry system integrating fruit tree (apple) with agricultural crops (tomato, brinjal, capsicum and black gram) resulted inhigher biomass production and are potential carbon sinks over agricultural cropping system. Among all the studied tree-cropcombinations, apple + tomato proved as the best combination, the farmer of the area should adopt from ecological and economical point of view.
