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 PLANT SPACING AND GA3 APPLICATION ON FLOWERING AND SEED PRODUCTION IN CALENDULA (Calendula officinalis L.)
    (UHF,NAUNI, 2019-08) BHARWAL, GAURAV; DILTA, B S
    ABSTRACT The present investigation titled, “Effect of plant spacing and GA3 application on flowering and seed production in calendula (Calendula officinalis L.)” was carried out at the Khaltoo experimental farm of Department of Seed Science & Technology,Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2017 to 2019. The experiment was laid out in RBD (Factorial) with 24 treatment combinations of four levels of spacing i.e. S1 (30 × 30 cm), S2(30 × 25 cm), S3 (30 × 20 cm) and S4(30 × 10 cm) and six doses of GA3 i.e. G0 (0 ppm), G1(50 ppm), G2(100 ppm), G3 (150 ppm), G4 (200 ppm) and G5 (250 ppm) replicated thrice. Among different levels of spacing, S1(30 × 30 cm) recorded maximum values for days to first flowering (71.67 days), number of flowers per plant (46.08), size of flower (5.11 cm), duration of flowering (80.16 days), number of seeds per head (46.11), seed yield per plant (19.67 g),1000 seed weight (9.19 g), germination percentage (87.78 %), speed of germination (13.61), seed electrical conductivity (0.99 dS/m), seedling length (8.41 cm), seedling dry weight (5.80 mg), seed vigour index-I (731.50) and seed vigour index-II (506.82). Whereas, spacing S4 (30 × 10 cm) recorded maximum values for plant height (60.72 cm) and seed yield per plot and per hectare (220.20 g and 2202.00 kg, respectively). The application of GA3@ 250 ppm resulted in highest values for plant height (66.27 cm), number of flowers per plant (42.79), size of flower (5.16 cm), duration of flowering (81.24 days), number of seeds per head(45.68), seed yield per plant (17.00 g), seed yield per plot andperhectare(215.72g and2157.20kg, respectively), 1000 seed weight (9.30 g),germination percentage (88.28 %), speed of germination (13.58), seed electrical conductivity (1.13 dS/m), seedling length (8.40 cm), seedling dry weight (6.04 mg), seed vigour index-I (742.58) and seed vigour index-II (534.91). Whereas, with the application of GA3 @ 0 ppm, plants took maximumtime for first flowering (71.50days). The interaction,S1 × G5 i.e.a plant spacing of30 × 30 cmalong with application of 250 ppm GA3 recorded maximum values in terms of most of the growth, flowering, seed yield per plant and seed quality parameters. However, maximum seed yield per plot and per hectare was found in the interaction, S4 × G5 i.e. when spacing was kept at 30 × 10 cm a part along with the application of GA3 @ 250 ppm, but the effects were found to be stastically at par with the interactions, S4 × G4, S4 × G3, S3 × G5, S3 × G4, S2 × G5 and S1 × G5. So, it is concluded that for better growth, flowering, improved seed yield and quality, the plantsbe spaced at30 × 30cm a part along with the application ofGA3@ 250 ppm.
