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.

    Cultivation of blue oyster mushroom [Hypsizygus ulmarius (Bull.: Fr.) Redhead] under sub-tropical zone of Himachal Pradesh
    (College of Horticulture and Forestry, Neri, Hamirpur, 2021-10-29) Aditya, Aditya; Jarial, R S
    The present investigation entitled “Cultivation of blue oyster mushroom [Hypsizygus ulmarius (Bull.: Fr.) Redhead] under sub-tropical zone of Himachal Pradesh” was carried out in the Mushroom Research Laboratory, Department of Plant Pathology, Dr Y. S. Parmar University of Horticulture and Forestry, College of Horticulture and Forestry, Neri, Hamirpur, Himachal Pradesh during the year 2019-21. Nutritional and physiological studies along with mycelial growth and biomass of H. ulmarius were studied on different media, different levels of pH and temperature regimes. Among different media tested potato dextrose agar exhibited significantly higher (41.44 mm) diametric growth followed by malt extract agar (32.63 mm) medium. The biomass production of test fungus was maximum (0.52 g) in carrot extract broth and minimum (0.04 g) was recorded in Czapek's Dox broth medium. A pH level 8.0 and temperature 25oC was found to be optimum for the growth of H. ulmarius. Bajra grains were found to be an excellent grain substrate for spawn preparation, as it supported faster and enhanced growth (11 days) of test fungus followed by jowar grains (13 days). Out of seven different grain spawn evaluated on standard substrate (wheat straw), minimum time (13.67 days) for spawn run, minimum number (20.33 days) of days for first flush, maximum number (38.33) of sporocarps in first flush were recorded on bajra grain spawn. However, longest (5.37 cm) stipe length, maximum (8.57 cm) cap diameter and maximum yield (768.00 g/600 g dry substrate) exhibiting maximum (128.00 %) biological efficiency was recorded on bajra grain spawn. Out of five spawn doses, minimum time (12.62 days) for spawn run, maximum number (42.33) of basidioma and highest yield (794.00 g/600 g dry substrate) with 132.33 per cent biological efficiency was recorded on wheat straw substrate spawned @5.0 per cent spawn dose. Out of seven production substrates evaluated, minimum time (14.66 days) for spawn run, first flush (20.66 days), maximum number of sporocarps (37.33) and maximum yield (744.00 g/600 g dry substrate) with highest (124.00 %) biological efficiency was recorded on wheat straw substrate. Moreover, longest stipe length (6.46 cm) on pine needles substrate and maximum (10.13 cm) cap diameter was recorded on maize straw followed by wheat straw substrate. Among six additive supplements amended in wheat straw substrate evaluated at six different doses for the production of H. ulmarius, cotton seed hull at the rate of 10.0 per cent took minimum time (8.33 days) for spawn run and produced maximum number (70.64) of basidioma with maximum (3537.33 g/2 Kg dry substrate) yield and high (176.87 %) biological efficiency in comparison to wheat straw alone (123.50 %). Mustard cake supplemented with wheat straw even at lowest (5.0 %) supplement dose completely inhibited the mycelial growth of the fungus. Commercially H. ulmarius was cultivated on top three selected substrates and supplements with best spawn at their best doses to analyse the yield and biological efficiency. Minimum time (9.60 days) for spawn run, maximum number (86.33) of basidioma, highest (8999.00 g/4.0 Kg dry substrate) yield and biological efficiency (224.97 %) was recorded in wheat straw substrate supplemented with cotton seed hull at the rate of 10.0 per cent followed by the same substrate supplemented with gram flour (213.82 %) and rice bran (207.15 %) at same supplementation dose (10 %). The hydrogen ion concentration (pH) of the substrate decreased with the progression of the crop while, electrical conductivity values from the zero days of spawning to 56 days of crop duration increased significantly
