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.

    EFFECT OF NANOPARTICLES SEED PRIMING AND FOLIAR SPRAY ON GROWTH, SEED YIELD AND QUALITY ATTRIBUTES IN OKRA [ABELMOSCHUS ESCULENTUS (L.) MOENCH]
    (UHF Nauni, 2024-04-24) AKSHAY KUMAR WALIA; Ashok Thakur
    The present investigations entitled, “Effect of nanoparticles seed priming and foliar spray on growth, seed yield and quality attributes in okra [Abelmoschus esculentus (L.) Moench]” were carried out at Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2022 to 2023. The first experiment was laid out in Completely Randomized Design (CRD) in laboratory having 74 treatment combinations of four nanoparticles (zinc, magnesium, iron and boron) and their bulk counterparts (at 50, 100 and 150 ppm concentrations and for 18, 24 and 30 hours) with hydropriming for 24 hours and a control. Experimental results showed that the maximum values for seed quality parameters were observed when seed priming was done with ZnO NPs @ 150 ppm for 18 h with maximum germination (93.75%), shoot length, (20.55 cm), root length (12.90 cm), seedling length (32.37 cm), seedling dry weight (261.00 mg), seedling vigor index - I (3033.75), seedling vigor index – II (24.46) and germination after accelerated ageing (86.75 %). In the second experiment, the best performing treatments were compared with hydropriming and control, highest physiological quality was also recorded when priming was done with ZnO NPs @ 150 ppm for 18 h with maximum dehydrogenase activity (0.449), α-amylase activity (11.25 mm), mobilization efficiency (175.37 %), shoot length (13.98 cm), root length (9.30 cm), seedling fresh weight (698.73 mg), seedling dry weight (354.91 mg) and leaf area (7.39 cm2). The third experiment was carried out in the experimental field in randomized block design with 17 treatment and a control. Among the treatment under study, seed priming with ZnO NPs @ 150 ppm for 18 h along with ZnO NPs spray @ 150 ppm at flowering initiation and 50 % flowering was the best performing treatment with maximum values for growth, seed yield and quality parameters with highest emergence percentage (87.50 %), plant height at first and second spray (40.12 cm and 57.18 cm), number of primary branches per plant (8.10), Number of fruits per plant (15.51), fruit length (19.20 cm), number of pods per plant (14.13), seeds per pod (48.52), seed yield (29.64 g/plant, 0.65 kg/plot, 17.97 q/ha) and minimum number of days to pod harvest (96.53 DAS). Moreover, this treatment also recorded maximum values for seed quality of harvested seed viz., seed index (5.03 g), germination (92.62 %), seedling length (31.66 cm), seedling dry weight (256.63 mg), seedling vigor index - I (2932.44), seedling vigor index - II (23.77), germination after accelerated ageing (83.88 %) and minimum electrical conductivity (0.079 dSm-1). The maximum benefit cost ratio was also observed in the same treatment with a ratio of 2.94:1. Hence, it may be inferred from the outcomes of the investigation that seed priming with ZnO NPs @ 150 ppm for 18 h along with ZnO NPs spray @ 150 ppm at flowering initiation and 50 % flowering is an appropriate treatment combination for promoting the growth, seed yield as well as quality attributes in Okra.
