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 PROPAGATION METHOD AND GRAFTING HEIGHT ON PERFORMANCE OF APPLE NURSERY
    (UHF,NAUNI, 2022-12) BHANDARI, ROHIN; SHARMA, NAVEEN C
    ABSTRACT The present investigation entitled “Effect of propagation method and grafting height on performance of apple nursery” was carried out at the fruit nursey block of Department of Fruit Science, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan, (HP) during 2021-22. EMLA 106 and ‘Red Velox’ were used as rootstock and scion, respectively. The treatments comprised of 2 propagation methods viz. Tongue grafting (P1) and Chip budding (P2) and 3 propagation heights viz. 6 inches (H1), 9 inches (H2) and 12 inches (H3). The experiment was laid out in a Randomized Block Design (Factorial) with six treatment combinations which were replicated four times. The results of experiment reveal that among the different propagation methods applied, tongue grafting exhibited maximum scion sprouting (83.93%), bud take success (82.68%), scion height (106.44 cm), scion diameter (11.61 mm), number of leaves (56.23), leaf area (24.58 cm2) fresh weight (71.91 g) & dry weight (38.35 g) of shoots, fresh weight (40.44 g) & dry weight (24.76 g) of roots, length of main root length (32.38 cm), total root length (7.82 m), leaf N (2.31 %), P (0.26 %), K (1.72 %) and proportion of saleable plants (80.77 %). However, irrespective of propagation methods, maximum bud sprouting (91.51 %), bud take success (90.76 %), scion height (114.78 cm), scion diameter (11.48 mm), number of leaves (60.55), leaf area (25.84 cm2), fresh weight (56.78 g) & dry weight (41.58 g) of shoots, length of main root (33.87 cm), total root length (7.63 m), leaf chlorophyll content (3.04 mg/g), leaf N (2.31 %), P (0.25 %), K (1.74 %) and proportion of saleable plants (88.79 %) as well as minimum days taken to bud sprout (8.63) were recorded in plants propagated at 6 inches. Among the interaction between methods and heights of propagation, the plants propagated through tongue grafting at 6 inches exhibited significantly higher bud sprout & bud take success (94.78 %), scion height (127.65 cm), number of leaves (64.70), fresh weight (81.43 g) % dry weight (43.43 g) of shoots, length of main root (34.02 cm), total root shoot biomass (61.51 g), leaf chlorophyll content (3.07 mg/g) and proportion of saleable plants (93.25 %) and minimum days taken to bud sprout (7.25). Thus, tongue grafting performed at 6 inches proved to be the best combination of propagation method and height to produce high grade apple nursery plants with good root and shoot system.
