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.

    INTEGRATED NUTRIENT MANAGEMENT STUDIES IN ONION
    (UHF,NAUNI, 2019-12) NEGI, MANISHA; SHARMA, J C
    ABSTRACT The present investigation entitled “Integrated nutrient management studies in onion” was carried out at the Experimental Farm, Department of Soil Science and Water Management, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during rabi season of 2017-18 and 2018-19. Different combinations of organic and inorganic sources of nutrients were tried in the form of nine treatments viz. T1 (Absolute control), T2 (RD of FYM + NPK), T3 (5 % Jeevamrut), T4 (RD of FYM + NPK through FYM), T5 (RD of FYM + 5 % Jeevamrut), T6 (VC + RD of NPK through FYM), T7 (VC + 5 % Jeevamrut), T8 (50 % FYM + 50 % VC + RD of NPK through FYM) and T9 (50 % FYM + 50 % VC + 5 % Jeevamrut) in a plot of 2.25 × 1.20 m2 dimension. The experiment was laid out in a randomised block design (RBD) with three replications involving a spacing of 15 × 10 cm. The seedlings of onion cv. Nasik Red were planted on 27th November during 2017 and 1st November during 2018. The results revealed significantly highest post harvest fertility status of macronutrients (NPK) (386, 156.6 and 384.1 kg ha-1, respectively) and their uptake (122.5, 16.7 and 67.4 kg ha-1, respectively) was recorded under recommended INM practice i.e. 125 N: 75 P: 60 K kg ha-1 + FYM @ 250 q ha-1 (T2). The close scrutiny of purely organic module T6 (VC - equivalent to N content of recommended FYM + RD of NPK through FYM on N equivalent basis) showed it next best in values with respect to available NPK and their uptake. Similarly, significantly highest bulb and biological yield (295.5 and 441.9 q ha-1, respectively) and yield contributing component i.e. bulb size (19 cm²) as well as net income (4,74,812 ` ha-1) with a relatively higher B:C ratio (4.1:1) was recorded under recommended INM practice (T2). It was closely followed by purely organic module T4 (RD of FYM + RD of NPK through FYM on N equivalent basis) with regards to bulb and biological yield, yield contributing component, net income and B:C ratio. The plots fertilized with RD of FYM + RD of NPK through FYM on N equivalent basis has recorded only 13.6 per cent less bulb yield in comparison with recommended INM practice (T2). Therefore, the purely organic modules T4 (RD of FYM + RD of NPK through FYM on N equivalent basis) and T6 (VC - equivalent to N content of recommended FYM + RD of NPK through FYM on N equivalent basis) with on farm production of VC can be suggested for organic cultivation of onion.
