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.

    IMPACT AND ASSESSMENT OF PLANT GROWTH PROMOTING RHIZOBACTERIA ON GROWTH AND YIELD OF APPLE PLANT (Malus domestica Borkh)
    (UHF, NAUNI, 2018-11) ANKIT; CHAUHAN, ANJALI
    ABSTRACT Apple cultivation has revolutionized the socio-economic conditions of farmers and plays a pivotal role in the economy of growers. It is grown over an area of 277000 ha with annual production of 2242000 metric tons in Himachal Pradesh. Indiscriminate use of chemical fertilizers and emergence of several fungal diseases leads to the deterioration of soil health characteristics and fertility. PGPR can reduce chemical fertilizers application and economically, environmentally beneficial for lower production cost as well as recognize the best soil and crop management practices to achieve more sustainable agriculture as well as fertility of soil. Therefore, the present study was aimed to evaluate the effect of plant growth promoting rhizobacteria on growth and yield of apple plant (Malus domestica Borkh). Bacillus licheniformis B6 already isolated from apple rhizosphere was assessed for its growth promotion potential of apple at fresh plantation and re-plantation sites of Rohru and Theog of Shimla district and found significant increase in all plant parameters viz. shoot length (40.05% and 38.83% ), shoot diameter (28.93% and 20.16% ) and shoot length (18.68% and 28.23% ) maximum increase over control at fresh and re-plantation repectively.B6 inoculation also resulted in percent increase in available NPK content of soil. Also the effect of Bacillus licheniformis B6 inoculation on yield and quality parameters of apple was assesed at Kiari, Kotkhai and resulted in 34.51% increase in shoot length, 23.11% increase in yield per tree, 2.69% increase in fruit weight and 13.43% increase in TSS. Impact and assessment of rhizobacterial population associated with selected apple orchards was also quantified. Total of forty eight morphologically different bacterial isolates were selected for in vitro screening of plant growth promoting traits. 62.50 per cent were P-solubilizers, 29.17 per cent were siderophore producers, 66.67 per cent were able to grow on nitrogen free medium, 37.50 per cent were IAA producers, 25.00 percent produced HCN and 35.41 percent showed antifungal activityagainst Dematophora necatrix.SA7 exhibited the maximum number of plant growth promoting attributes and showed 99% similarity with Bacillus cereus thus identified as strain ofBacillus cereus. The results of this study suggest that Bacillus licheniformis have the potential to increase the yield, growth, and nutrition of apple while Bacillus cereus SA7 emerge as a potential PGPR whose efficacy at field level need to be explored.
