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 SEED BIOPRIMING AND ITS EFFECT ON GROWTH, YIELD AND SEED QUALITY IN FRENCH BEAN (Phaseolus vulgaris L.)
    (UHF,NAUNI, 2019-05) NEGI, SHIVANGI; BHARAT, NARENDER K
    ABSTRACT The present investigation entitled “Studies on seed biopriming and its effect on growth, yield and seed quality in French bean (Phaseolus vulgaris L.)” was conducted during the years 2017 and 2018 under laboratory and field conditions in the Department of Seed Science and Technology, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP). Nine indigenous isolates of bioagents including three plant growth promoting rhizobacteria (PGPR-1, PGPR-2 & PGPR-3), three rhizobial biofertilizers (Rhizobium strain- B1, Rhizobium strain- B2& Rhizobium strain- P1) and three biocontrol agents (Trichoderma harzianum, T. viride & T. virens) were screened for their efficacy as seed biopriming under laboratory conditions following standard methods of seed quality and health testing as prescribed by International Seed Testing Association. On the basis of these tests, PGPR-1, Rhizobium strain- B1 and T. viride were selected from their respective categories for further studies. The doses (cfu/ ml) and time durations (hr) for seed biopriming with these three bioagents were also standardized following standard methods. On the basis of in vitro studies, the doses and time durations of biopriming finalized were as PGPR-1 @109 cfu/ml for 6 hrs, Rhizobium strain- B1 @109 cfu/ml for 8 hrs and T. viride @ 107 cfu/ ml for 6 hrs. These bioagents were then evaluated under storage and field conditions. Ten treatment combinations were used viz., PGPR-1 (T1), Rhizobium strain- B1(T2), Trichoderma viride (T3), PGPR + Rhizobium strain B1 (T4), PGPR + Trichoderma viride (T5), Rhizobium strain B1 + Trichoderma viride (T6), PGPR + Rhizobium strain B1 + Trichoderma viride (T7), Hydropriming (T8), Carbendazim (Treated control) (T9) and Untreated control (T10). Under storage conditions up to nine months, seed biopriming with PGPR-1 + Rhizobium strain B1 (T4) resulted significantly higher germination (91.50 %), speed of germination (6.86), seedling length (31.90 cm), seedling dry weight (1929.60 mg), seedling vigour index- length (SVI-L) (2929.95) and seedling vigour index- mass (SVI-M) (170131.40) and lowest seed mycoflora (3.75 %) as compared to carbendazim treatment and untreated control. Under field conditions in both the years, field emergence (95.18 %), plant height at 30 days after sowing (34.09 cm), plant height at final harvest (56.99 cm), days to pod harvest (52.33), harvest duration (18.67), pod length at final harvest (16.83 cm), number of pods per plant (20.17), dry pod weight (2.72 g), pod yield per plant (38.64 g), number of seeds per pod (7.17), seed yield per plant (20.76 g), seed yield per plot (875.33 g), seed yield per hectare (23.34 q), 100 seed weight (34.19 g), quality of harvested seeds were recorded significantly higher in PGPR-1 + Rhizobium strain B1 (T4) as compared to carbendazim seed treatment and untreated control. This treatment combination also reduced incidence of diseases like, Rhizoctonia root rot (2.60%) and Angular leaf spot (2.97%) significantly as compared to carbendazim seed treatments and untreated control. It can be concluded from the present investigation that seed biopriming of French bean cv. Contender with PGPR-1+Rhizobium strain B1 @ 109 cfu/ml for 8 hours was an effective treatment which significantly improved plant growth, pod yield, seed yield, seed quality and seed vigour and reduced disease incidence as compared to seed treatment with carbendazim @ 0.2% as well as untreated control under field conditions.
