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 SEED PRIMING TREATMENTS AND FOLIAR APPLICATION OF PACLOBUTRAZOL ON SEED YIELD AND QUALITY IN SALVIA (Salvia splendens Sellow ex Schult.)
    (UHF Nauni, 2024-08-21) ANU SHARMA; BS Dilta
    The investigation titled, "Effect of seed priming treatments and foliar application of paclobutrazol on seed yield and quality in salvia (Salvia splendens Sellow ex Schult.)" was carried out at Research Farm and Laboratory of the Department of Seed Science and Technology, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2021-22 and 2022-23. First experiment was carried out in laboratory in completely randomized design (CRD) replicated four times, with 100 seeds per replication. There were twenty seed priming treatments viz. hydro priming for 12 hours, hot water treatments @ 50°C for 10 minutes, 15 minutes and 20 minutes and soaking of seeds in distilled water overnight, priming of seeds in the solutions of GA3 (100 ppm, 150 ppm, 200 ppm, 250 ppm for 12 hours), cow urine (5, 10 , 15 and 20 % for 12 hours), cow dung slurry for 12 hours and 24 hours and bio priming of seeds with Pseudomonas chlororaphis for 12, 24, 48, 72 and 96 hours including untreated control. Amongst them, priming of seeds in cow dung slurry for 24 hours significantly resulted in the increasing of germination percentage (85.38 %), seedling length (5.72 cm), seedling dry weight (2.36 mg), seed vigour index-I (488.44), seed vigour index-II (201.79) and it was followed by cow urine @ 10 % for 12 hours and GA3 @ 150 ppm for 12 hours. However, lowest germination percentage (51.62 %), seedling length (3.42 cm), seedling dry weight (1.48 mg), seed vigour index-I (176.62), seed vigour index-II (76.51) was observed in the treatment of bio priming with Pseudomonas chlororaphis for 96 hours. The second experiment was laid out in RCBD (factorial) for field studies and CRD (factorial) for laboratory studies. To carry out the second experiment, seed priming treatments viz., cow dung slurry for 24 hours, cow urine @ 10% for 12 hours and GA3 @ 150 ppm for 12 hours were selected to raise the stocky and good quality seedlings in pro trays under poly house conditions. Then the salvia seedlings (treatment wise) were transplanted under field conditions in 48 plots of size 1 m × 1 m to raise successful crop. After 40 days of transplanting, the salvia plants were sprayed with paclobutrazol (0, 5, 10 and 20 ppm). Data on various growth, flowering and seed yield and quality contributing characters were recorded. From the present investigation, it was concluded that the treatment combination, seed priming with cow dung slurry for 24 hours and foliar application of paclobutrazol @ 10 ppm after 40 days of transplanting had exhibited highest values for plant spread (42.34 cm), number of branches per plant (12.03), number of spikes per plant (16.83), number of pods per plant (546.03), seed yield (7.36 g/plant, 66.20 g/plot and 496.46 kg/ha), 1000 seed weight (3.805 g), germination percentage of freshly harvested seeds (83.75 %), seedling length (5.80 cm), seedling dry weight (2.22 mg), speed of germination (13.61) as well as lowest EC (0.146 dS/m). However, maximum plant height (46.51 cm), spike length (17.31 cm) and number of florets per spike (60.67) was reported in the plants raised from seed lot primed with cow dung slurry for 24 hours and without application of paclobutrazol. Accordingly, it may be inferred from the outcomes of the investigation that seed priming with cow dung slurry for 24 hours along with the foliar application of paclobutrazol @ 10 ppm is an appropriate treatment combination for promoting the growth, flowering as well as seed production in salvia under mid hill conditions of Himachal Pradesh
