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 effect of biological control agents on plant growth, disease incidence, seed yield and quality attributes in cucumber
    (UHF,NAUNI, 2023-10-19) ARSHIA MANDIAL; NARENDER K BHARAT
    ABSTRACT The present investigation entitled “Studies on effect of biological control agents on plant growth, disease incidence, seed yield and quality attributes in cucumber” was conducted during the years 2021 and 2022 under laboratory and field conditions in the Department of Seed Science and Technology, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP). Ten indigenous isolates of bioagents including five bacterial bioagents (Bacillus licheniformis strain B6, B. pumilus strain MK5, B. subtilis strain RDO10, Pseudomonas aeruginosa strain N2S6, P. fluorescens strain HB-13) and five fungal bioagents (Trichoderma atroviride ta001, T. atroviride ta002, T. atroviride ta003, T. atroviride ta004, T. atroviride ta005 were screened for their bio-efficacy as seed treatment under laboratory conditions following standard methods of seed quality and health testing as prescribed by International Seed Testing Association. On the basis of first experiment, B. pumilus strain MK5 and T. atroviride ta001 were selected for field evaluation. Twelve treatment combinations of these bioagents based on seed treatment, soil application and foliar sprays were used viz., T. seed priming+ T. foliar spray (T1), B. seed priming+ Bacillus foliar spray (T2), T. seed coating+ T. foliar spray (T3), B. seed coating+ B. foliar spray (T4), T. soil application+ T. foliar spray (T5), B. soil application+ B. foliar spray (T6), T. seed priming+ B. seed coating plus B. + T. foliar spray (T7), B. seed priming+ T. seed coating plus (B. + T.) foliar spray (T8), B. seed priming + T. soil application plus (B. + T.) foliar spray ( T9), T. seed priming+ B. soil application plus (B.+ T.) foliar spray ( T10), fungicide treatments (T11) and untreated control (T12). Under field experiments, lowest male female flowers ratio (9.95), minimum number of days to first picking (56.75 days), maximum harvest duration (30.17 days), number of marketable fruits/plant (11.75), average fruit weight (258.06 g), fruit length (21.58 cm), fruit diameter (5.08 cm), fruit yield/plant (2.74 kg), fruit yield/plot (24.63 kg), fruit yield/ha (350.25 q), number of seeds/fruit (281.20), seed yield/plant (68.05 g), seed yield/plot (612.44 g), seed yield/ha (871.03 kg), maximum 1000 seed weight (30.27 g), minimum severity of powdery mildew (1.62 %) was recorded under combined treatment of Trichoderma atroviride ta001 seed priming+ soil application with Bacillus pumilus strain MK5 as well as foliar sprays of T. atroviride ta001+ B. pumilus strain MK5 (T10) and minimum was recorded under untreated control. It can be concluded from the present investigation that a treatment combination comprised of seed priming with T. atroviride (ta001) @ 106 cfu/ml for 6-8 hours before sowing + soil application with B. pumilus strain MK5 @ 1kg FYM/m2 (inoculated @100 ml/kg FYM of 108 cfu/ml) at the time of sowing plus foliar spray of T. atroviride (ta001) @ 106 cfu/ml + B. pumilus strain MK5 @ 108 cfu/ml (@10ml/ m2) enhanced plant growth parameters, yield attributes such as number of fruits per plant, average fruit length (cm), average fruit diameter (cm), average fruit weight (g) and quality of harvested seed in cucumber cv. Solan Srijan. This treatment also provided the control of important disease like powdery mildew up to 86.79% over control
