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.

    AN INNOVATIVE GREEN TECHNOLOGY FOR AGRICULTURAL WASTE UTILIZATION
    (NAUNI,UHF, 2020-10) SHARMA, KANIKA; SHARMA, NIVEDITA
    ABSTRACT In the present investigation, different agricultural wastes were collected from Himachal Pradesh and their adjoining states i.e. Punjab and Haryana and an attempt had been made to utilize this waste as substrate for its enzymatic degradation to enhance their saccharification and bioconversion to ethanol by co-fermentation with ethanologens. Based upon the chemical composition of mixed agricultural waste and large availability of rice straw, these were finally selected for further study. Different physico-chemical pretreatment methods applied to rice straw/mixed waste, where maximum reducing sugars i.e. 46.98 and 44.45 mg/g from rice straw/mixed waste respectively were obtained in microwave pretreatment. After optimization of different process parameters by one factor at a time (OFAT) approach for enzymatic saccharification under SmF, highest reducing sugars reported from untreated and pretreated rice straw/mixed waste were 34.40 and 56.70 mg/g; 38.0 and 63.50 mg/grespectively, at enzymatic ratio of 3.5:1.5, 50oC temperature, 5.5 pH, incubation period 72 h and 7.5% biomass loading followed by CCD of RSM by varying temperature, pH and incubation time. SEM analysis revealed that the surface structure of rice straw/mixed waste was significantly changed after pretreatment and enzymatic hydrolysis. The reducing sugars so obtained were analyzed using HPLC technique. In 2nd mode i.e. SSF (biological degradation), two fungal strains selected P. chrysoporium and P. ostreatus fungal strains had showed maximum amount of reducing sugars produced i.e. 55.70 and 49.05 mg/g by using microwave pretreated rice straw and mixed waste respectively. After optimization of process parameters through OFAT and RSM maximum reducing sugars from untreated and pretreated rice straw (450 watt) /mixed waste (600 watt) had the critical values as 51.12 and 37.98 mg/g; 71.99 and 73.10 mg/g respectively, at 30 and 25oC temperature and incubation period 10 days respectively. Among two processes of ethanol fermentation evaluated in the present study, SHF was found to be the best in terms of highest ethanol productivity with S. cerevisiae I+ P. stipitis as best fermenting microorganism from enzymatic saccharified and fungal degraded sugary syrup. Estimation of bioethanol production after enzymatic saccharfied/ biological degrdaded microwave pretreated rice straw/mixed waste hydrolysate fermented by co-culture of S. cerevisae I and P. stipitis was done with the help of GC-MS. Scale up of ethanol fermentation using 7.5 l stirred tank bioreactor, batch conversion of rice straw/mixed waste enzymatic saccharified hydrolysate to ethanol was carried out by co-culture of S. cerevisiae I + P. stipitis under SHF. The highest ethanol yield of 52.14 and 46.89 g/l with 88.12 and 80.01 % of fermentation efficiency was achieved after 48 and 36 h of fermentation with an agitation speed of 200 rpm and aeration rate of 0.05vv, pH 6 at 25 ±2°C and inoculating the bioreactor with 24 h old co-culture of yeasts (S. cerevisiae I + P. stipitis). Also to combat the pollution problem, value addition of agricultural waste for cultivation of mushroom supplemented with apple pomace had emerged as an ecofriendly technique with higher yield and better utilization substrate.
