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 NATIVE MICROBIAL BIOAGENTS FORMULATIONS IN BELL PEPPER DISEASE MANAGEMENT
    (UHF,NAUNI, 2023-12-11) ADITI ANAND; BHUPESH K GUPTA
    In present investigations, the effect of incubation period, incubation temperatures, dilution factor and their interactions on colony forming units were studied and it was noticed that if Trichoderma atroviride is incubated for four days at 29±1°C then the desired number of cfu count can easily be obtained and quantified at dilution factor 1012. Similarly, when Bacillus subtilis is incubated for three at 31±1°C, then the desired number of cfu count can easily be obtained and quantified at 1014 dilution factor for the production of formulations. The shelf-life trends obtained during this study up to 90 days were indicative that at 4°C, the formulations retained comparatively higher number of viable propagules as compared to room temperature. It was evident from the research that the storability and retention of cfu viability is directly proportional to the CMC concentration in talc-based formulations, and inversely proportional to the talc concentration. It has also been documented that using glycerol as a stabilizer increased the shelf life of Trichoderma atroviride and Bacillus subtilis liquid formulation. Hence it was investigated that Trichoderma atroviride talc-based formulation with 1:2 talc and 0.75 per cent CMC was evaluated as the best formulation as it retained 20.8×107 cfu/g after 90 days of storage, whereas, the best talc-based formulation of Bacillus subtilis was having 1:25 talc ratio and 0.75 percent CMC as it retained cfu count of 34.7×109 cfu/g after 90 days of storage. The best formulated product of Trichoderma atroviride and Bacillus subtilis had 9 per cent and 7.5 per cent glycerol concentration, respectively, as it retained more cfu count than the desired cfu count of 2×106 and 2×108 cfu/ml even after 90 days of storage. It was also concluded that the native microbial bioagent formulations not only helped in mitigating the losses due to soil-borne diseases but also helped in improving plant growth because the microbial consortium of liquid formulation of (Trichoderma atroviride + Bacillus subtilis) showed minimum disease incidence (44.44%).
