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.

    ABSTRACT The present studies were carried out in a private orchard at Matiana (Shimla) during the year 2014-2015. Five years old trees of uniform size and vigour planted at 3.0 x 3.5 m spacing were subjected to 10 treatments viz. calcium nitrate (2.25 kg), urea (760 g), calcium nitrate + urea (1.125kg and 380g), NPK mixture 12:32:16 and calcium nitrate (550g and 1.830kg), N:P:K mixture 12:32:16 and urea (550g and 620g), Di-ammonium phosphate and calcium nitrate (380g and 1.820kg), di-ammonium phosphate and urea (380g and 620g), NPK mixture 12:32:16 and calcium nitrate + urea (550g and 920g + 310g), diammonium phosphate and calcium nitrate + urea (380g and 910g + 310g), calcium ammonium nitrate/control (1.4 kg). The treatments were replicated thrice and experiment was laid out in randomized block design. Tree height, spread, volume, leaf area, annual shoot growth and chlorophyll content were significantly increased by calcium nitrate + urea application, however, combination of di-ammonium phosphate and urea resulted in lowest vegetative growth attributes. The calcium nitrate + urea treatment also had significantly improved fruit set, yield and yield efficiency and reduced fruit drop. Trees subjected to calcium nitrate + urea treatment exhibited significantly higher fruit weight, total soluble solids, total and reducing sugars and lowest titratable acidity. However, maximum fruit length and anthocyanin content were observed with calcium ammonium nitrate and fruit diameter as well as firmness with the application of calcium nitrate. The maximum leaf N, K and Mg contents were recorded in calcium nitrate + urea treatment but leaf P and Ca were observed highest in trees treated with combination of di-ammonium phosphate and calcium nitrate and calcium nitrate, respectively. Soil pH, EC and OC were not influenced by various nitrogen sources, however, significantly higher soil N and K were recorded under calcium nitrate + urea treatment but maximum soil P was observed with di-ammonium phosphate and calcium nitrate application.
