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.

    Tree-crop interactions in Harar (Terminalia chebula Retz.) and Aonla (Phyllanthus emblica L.) based agroforestry systems
    (COLLEGE OF HORTICULTURE AND FORESTRY, DR Y S P UHF, NERI, HAMIRPUR, 2020-09-20) Bhatia, Avinash Kumar; Sharma, Kamal
    The studies entitled “Tree-crop interactions in Harar (Terminalia chebula Retz.) and Aonla (Phyllanthus emblica L.) based agroforestry systems” were carried out at Khaggal (Neri-II) Experimental Farm of Department of Silviculture and Agroforestry, College of Horticulture and Forestry, Neri-Hamirpur under subtropical conditions of Himachal Pradesh. The experiments were designed to evaluate the effect of trees (Harar and Aonla) on the growth and yield parameters of agricultural crops (maize, mash and arhar) along with soil health, carbon sequestration potential and bio-economics appraisal under different tree-crop combinations. The trial was laid out in Randomized Block Design, having nine treatment combinations (sole maize, maize + Harar, maize + Aonla, sole mash, mash + Harar, mash + Aonla, sole arhar, arhar + Harar and arhar + Aonla) with four replications in order to assess the biomass, carbon stock and economics of the various tree-crop combinations while for growth, yield and soil physico-chemical properties, the trial was laid out in Randomized Block Design having three treatment combinations viz. sole agricultural crop, agricultural crop + Harar and agricultural crop + Aonla with twelve replications. The results indicated that trees suppressed the growth and yield of agricultural crops significantly. Among all the physico-chemical properties of the soil, porosity, soil moisture, pH and organic carbon were found to be affected significantly while, the bulk density and particle density remained unaffected under different tree-crop combinations, at soil depths, 0-15 cm and 15-30 cm. Results also indicated that with increase in soil depth from 0-15 cm to 15-30 cm, bulk density, particle density, soil moisture, EC and pH increased whereas, reverse trend was observed for porosity and soil organic carbon. The available N, P and K contents decreased with the increase in soil depth under all tree + crop associations. Among various agricultural crops, the maximum nitrogen and potassium contents were observed under maize while, the maximum phosphorus under arhar. Among growth parameters, the plant height/length revealed the highest and positive correlation coefficients with grain yield in all the three agricultural crops and thus, can be used as selection indicator for higher economic yields. Among all tree + crop combinations, the highest total biomass (77.80 t ha-1 ) and total carbon stock (38.90 t ha-1 ) were recorded under maize + Harar. From economics point of view, the maximum (80,471.49 Rs. ha-1 ) gross returns were obtained for maize + Aonla yet the maximum (42,684.40 Rs. ha-1 ) net returns and benefit-cost ratio (2.14) were worked out for mash + Aonla. The increase in soil physico-chemical properties indicated that these tree-crop combinations are sustainable. Agroforestry systems with perennial crops are potential carbon sinks over agricultural cropping system. Among all the tree-crop combinations studied, mash + Aonla proved to be the best combination, the farmer of the area should adopt from ecological and economical point of view.
