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 INTEGRATED NUTRIENT MANAGEMENT AND SHOOT BENDING ON GROWTH AND FRUITING OF PLUM (Prunus salicina Lindl.) cv. BLACK AMBER

    Abstract The present study entitled “Effect of integrated nutrient management and shoot bending on growth and fruiting of plum (Prunus salicina Lindl.) cv. Black Amber” was conducted at farmer’s orchard in Village Mangsu, Distt. Shimla (H.P.) during 2021 and 2022. The study was conducted in 2 experiments. The experiment-I on integrated nutrient management consisted of 11 treatments with 4 replications in randomized block design (RBD). The chemical fertilizer (NPK) were applied at 4 levels of the recommended doses of fertilizers i.e. 100%, 80%, 70%, and 80%, as per package of practices of the University. Farmyard manure and vermicompost were applied to compensate the 10% and 20% recommended dose of nitrogen. Microbial inoculants were biofertilizer (Azotobacter and PSB) and jeevamrit. The treatment T6 (70 % RDF + 10 % RDN through vermicompost + biofertilizer) recorded the highest annual shoot growth, fruit set, fruit yield, photosynthesis rate, stomatal conductance, transpiration rate, fruit firmness, soil organic carbon, water holding capacity, soil porosity, soil Azotobacter count, soil dehydrogenase and acid phosphatase activity. Whereas, treatment T7 (70 % RDF + 10 % RDN through vermicompost + jeevamrit) recorded the maximum percent increase in tree volume, leaf chlorophyll content and fruit quality attributes namely. fruit weight, fruit size, TSS, total sugars, reducing sugars and non-reducing sugars content. All the treatments maintained the leaf nutrient status in optimum range during the study. The results of present investigation reveal the improved tree growth and productivity with lowering the fertilizer use in the orchard. The experiment-II consisted of 3 bending angle (45°, 60° and 90°) and 6 heading back treatments (25% head back, no head back, 50% head back, April pinching, May pinching and June pinching) with 3 replications in factorial RBD design. The fruiting and yield were significantly increased with increase in bending angle 90°>60°>45°, especially during the early years of plantation. The reduction in lateral growth was recorded in bent shoots due to reduction in annual growth increment. The integration of modern training and integrated nutrient management techniques in the plum orchard can help in maintaining the tree vigour and improve fruit quality.
