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.

    INFLUENCE OF PLANTING DATES, MULCHES AND GA3 APPLICATIONS ON SEED YIELD AND QUALITY OF AFRICAN MARIGOLD (Tagetes erecta L.) CV. ‘PUSA NARANGI GAINDA’
    (UHF,NAUNI, 2018-03) THAKUR, PRIYANKA; DILTA, B.S.
    ABSTRACT The present investigation entitled, “Influence of planting dates, mulches and GA3 applications on seed yield and quality of African marigold (Tagetes erecta L.) cv. Pusa Narangi Gainda” was carried out at the Khaltoo experimental farm of Department of Seed Science & Technology, Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2015 to 2017. The experiment was laid out in Split- Plot Design with 48 treatment combinations of three planting dates (viz., 1st July , 16th July and 1st August), four levels of mulching ( no mulch, crop residue mulch, black plastic mulch and silver-black plastic mulch) and four doses of GA3 (0, 50,100 and 150 ppm ) replicated thrice. Planting of seedlings was done at three different planting dates along with application of different mulches and the treatments of GA3 were applied after 45 days of transplanting as foliar spray. The data were recorded on various growth, flowering, seed yield and quality attributes and subjected to analysis of variance. The results obtained indicated that transplanting of seedlings in the 1st week of July (1st July), mulching of plants with silver-black sheet (M4) and spraying of plants with the highest concentration of GA3 (i.e. 150 ppm) alone as well as in combinations exhibited best performance in terms of minimum days taken to first flowering (days) and attaining maximum values w.r.t. plant height (cm), number of flowers per plant, size of flowers (cm), shoot fresh weight (g), shoot dry weight (g), root fresh weight (mg), root dry weight (mg), number of seeds per head, seed yield per plant (g), seed yield per plot (g), 1000 seed weight (g), germination percentage (%), seedling length (cm) and dry weight (mg), seed vigour index-I (Length) and seed vigour index-II (Mass) as well as lowest electrical conductivity of seeds (dS/m) in comparison to all other treatments. Therefore, transplanting of seedlings be commenced on in 1st week of July (1st July) and mulched with silver- black plastic sheet (M4) along with spraying of GA3 @ 150 ppm after 45 days of transplanting can be recommended for commercial seed production of marigold under mid hill conditions of Himachal Pradesh.
