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.

    STUDIES ON EFFECTS OF DIFFERENT ORGANIC SUBSTRATES ON QUALITY OF VERMICOMPOST
    (2013) DIPAK, KUMAR; UPADHYAY, G.P.
    ABSTRACT The present investigation entitled “Studies on the effects of different organic substrates on quality of vermicompost” was planned to work out the effects of various sources of organic matter such as animal dung, food waste, and kitchen wastes, saw dust, Parthenium, lantana, bagasse, pine needle etc. on the quality of vermicompost and population dynamics of earthworms. The nutrient contents viz. nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, iron, copper, manganese, and zinc were found significantly higher under lower carbon nitrogen ratio of vermicompost. The organic carbon content in the vermicompost was decreased at greater extent at lower carbon: nitrogen ratio (30:1) compared to higher one, whereas, decrease in C: N ratio was more under high C: N ratio (70:1) as compare to lower one. Other properties of vermicompost like pH, Electrical conductivity and Bulk density were also significantly higher in lower C: N ratio. Use of pine needle as substrate was found inferior compared to all other substrates, whereas, boiled pine needle proved to be better option for vermicomposting. The population dynamics of earthworm is greatly affected by quality of substrate and its carbon nitrogen ratio. The earthworm’s reproduction, growth and multiplication was also significantly affected by quality of substrates and their C: N ratio. The earthworm population in the vermicompost was higher in all the treatments at lower carbon: nitrogen ratio as compared to higher one. The quality of vermicompost and population dynamics of earthworms in vermicompost prepared from Parthenium in combination with cow dung, bagasse and kitchen waste was best compared to all other treatments. The use of boiled pine needle as substrate was found better as compared to un-boiled one for better quality. Substrates of higher carbon: nitrogen ratio produced poor quality of vermicompost and also takes more time for decomposition, however, carbon: nitrogen ratio of 30 to 40 was found optimum for the process of vermicomposting
