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.

    STUDIES ON RELATIONSHIP OF GROWTH STAGES OF MAIZE (Zea mays L.) WITH WEATHER PARAMETERS IN MID HILLS OF HIMACHAL PRADESH
    (2016) VERMA, GARIMA; BAWEJA, PARMINDER KAUR
    ABSTRACT A field experiment was carried out during kharif season of 2015 to study the relationship of growth stages of maize (Zea mays L.) with weather parameters in mid hills of Himachal Pradesh. The experiment consist of three dates of sowing viz., 10-06-2015,20-06-2015 and 30-06-2015 with two cultivars Vyas and HP 333 under irrigated and rain fed conditions, in the Experimental Farm under the department of Environmental Science, College of Forestry, Dr Yashwant Singh Parmar University of Horticulture and Forestry Nauni, Solan, Himachal Pradesh. Results indicated that the early sown maize cultivar HP-333 recorded high grain yield of 25.7 qha-1 by taking 138 days to mature under irrigated conditions. The delay in planting gradually decreased the yield by 8.8qha-1 due to shortened length of crop season by 34 days. The correlation coefficient among phenological stages and weather elements revealed that soil temperature at 5 cm depth reported high significance (r = 0.986). At grain development stage, relative humidity (0.874) dominated over sunshine hours (0.684).Various thermal indices including growing degree days (GDD), heliothermal units (HTU), heat use efficiency (HUE)and photothermal index for maize were calculated using standard methods .The accumulated GDD (1867.47 oC day) required to attain physiological maturity was significantly higher under early sown maize cultivar HP-333 as compared to late sown Vyas cultivar. The accumulated HTU (23328.39 oC day hr.) calculated for early sown was higher than late sown varieties. Thus, HP-333 observed to be more efficient due to high heat use efficiency (HUE= 0.17g (oC day )-1) during early sown maize as compared to late sown (HUE= 0.04g(oC day )-1). Regression models were developed to predict the flag leaf stage, milking, physiological maturity and grain yield based on accumulated GDD and accumulated HTU. Accumulated GDD predicted the grain yield more accurately (R2= 0.91).
