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 THE EFFECT OF ORGANIC MANURES, FERTILIZERS AND HARVESTING SCHEDULES ON GROWTH AND YIELD OF LEMONGRASS (Cymbopogon flexuosus Nees ex. Steud Wats)
    (UHF,NAUNI, 2021-09) ATTRI, SUBHAM; SOOD, MEENU
    ABSTRACT The present research entitled “Studies on the effect of organic manures, fertilizers and harvesting schedules on growth and yield of lemongrass (Cymbopogon flexuosus Nees ex. Steud Wats)” were carried out in the experimental field as well as in laboratory of Department of Forest Products, COF, UHF, Nauni, Solan (HP) during 2020-2021. In the first experiment ‘Morphological studies of Cymbopogon flexuosus’ lemongrass was found to be a tall, perennial aromatic plant which grows upto a height of 1.5 m. Stem was short, erect, smooth, cylindrical in shape, hollow at internodes, solid at nodes and dark purple in color. Roots were adventitious, fibrous and light brown in color with their length 15-30 cm. Leaves were slender, blade like, long, linear, tapering at both ends and glaucous green in color. The inflorescence was large with a length of 30-50 cm and the axis of the inflorescence was up to 12 nodes recorded. The florets were arranged alternatively on the central axis. A spikelet consists of two bracts called glumes were found which were smooth, concave and glabrous. A floret had lemma on the outer side with hair known as awn and palea on the inner side. Two styles with plumose and purple coloured stigma and three bilobed stamens were present in a floret, fruit is a caryopsis. In second experiment on ‘Effect of different organic manures, fertilizers and harvesting schedules on growth and yield of Cymbopogon flexuosus’ the growth and yield parameters were investigated. In this experiment eight treatments consisting of T1 (Control), T2 (NPK (60:45:45 kg/ha)), T3 (FYM (9.6 t/ha)), T4 (Vermicompost (3.3 t/ha)), T5 (Jeevamrit at 25, 40 and 55 days after planting), T6 (FYM + NPK (9.6 t/ha + 60:45:45 kg/ha)), T7 (Vermicompost + NPK (3.3 t/ha + 60:45:45 kg/ha)), T8 (Jeevamrit + NPK (Soil application at 25, 40 and 55 DAP + 60:45:45 kg/ha)) and four harvestings viz., first harvesting at 90 days after planting, second harvesting at 150 DAP, third harvesting at 210 DAP and fourth harvesting at 270 DAP were evaluated in RBD design with three replications in the field. The combined application of Jeevamrit (500 l/ha) + NPK (60:45:45 kg/ha)gave the maximum value of plant height (154.56 cm), number of leaves per plant (144.11), number of off shoots per plant (40.95), fresh weight per plant (134.59 g), dry weight per plant (102.87 g), estimated fresh herbage yield/ha (49.85 q/ha), estimated dry herbage yield/ha (38.10 q/ha), essential oil content (2.53%) andestimated essential oil yield/ha (96.52 kg/ha)and benefit:cost ratio (1.64)which was followed by the combination of Vermicompost (3.3 t/ha) + NPK (60:45:45 kg/ha). Results revealed that combined application of organic manures and inorganic fertilizers produced higher herbage and oil yield as compared to control and sole application.
