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 CULTIVATION OF Pleurotus cornucopiae (Paulet) Rolland ON DIFFERENT AGROFORESTRY SUBSTRATES IN HIMACHAL PRADESH
    (UHF,NAUNI, 2018-09) ARUNESH, KUMAR; JARIAL, R.S.
    ABSTRACT The present investigations entitled “Studies on cultivation of Pleurotus cornucopiae (Paulet) Rolland on different agroforestry substrates in Himachal Pradesh” was undertaken to evaluate various cultural requirements, grain substrate for spawn production and different agroforestry based substrates used for fruit body production of the test fungus. Out of five solid and liquid media tested, potato dextrose agar and potato dextrose broth were the best solid and liquid media, respectively and optimum temperature of 250C and pH 7.0 was found to be the best for better mycelial growth of the test fungus. Out of five grain spawn, minimum (7.33 days) time for spawn run was observed on jowar grain spawn and maximum (4.20) number of fruit bodies was observed in wheat grain spawn. Out of five substrates, minimum (16.30 days) time for spawn run, maximum (4.40) number of fruit bodies, was observed on wheat straw substrate. So far as morphological characters of P cornucopiae in different substrates was concerned, longest stipe length (23.92 mm), fruit body length (38.88 mm) and cap diameter (55.96 mm) was observed on wheat straw spawned with wheat grain spawn. Maximum yield (496.00 g/2kg substrates) was observed on wheat straw substrate spawned with wheat grain spawn. Biological effeciency of different substrates spawned with five grain spawn, ranged between 16.33 to 82.66 per cent. Out of five spawn doses, minimum (14.00 days) time for spawn run, maximum yield (517.33 g/2 kg substrate), maximum number of basidioma (7.33) and good biological efficiency (86.22 %) was recorded in wheat straw spawned at the rate of 5 per cent. However yield at 5 per cent rate of spawning was statistically at par with that at 4 per cent rate (507.33 g/2 kg substrate). For the production of P. cornucopiae, wheat straw proved to be the best substrate exhibiting minimum time for spawn run (16.33 days), maximum number of basidioma (20.49) and yield (1276 g/5kg substrate) as well as good biological efficiency (85.06%).Out of six supplements amended in wheat straw substrate evaluated at five different doses for the production of test mushroom, wheat bran supplemented at the rate of 6 per cent took minimum time for spawn run (12.00 days) and produced maximum (8.77) number of basidioma with highest yield (546.66 g /2 kg substrate) and good biological efficiency of 91.11 per cent in comparison to wheat straw supplemented with oat meal exhibiting a biological efficiency of 74.44 per cent only
