dc.description.abstractABSTRACT The present research entitled “Studies on the effect of organic manures, fertilizers and harvesting schedules on growth and yield of lemongrass (Cymbopogon citratus (DC.) Stapf)” were carried out in the experimental field as well as in laboratory of Department of Forest Products, COF, UHF, Nauni, Solan (HP) during 2021-22. Morphological studies revealed that Cymbopogon citratus was found to be a tall, perennial aromatic grass which grows upto a height of 19.69 cm to 131.93cm. The stem was erect, smooth, cylindrical in shape, swollen node and dark purple ring at vegetative stage, turning into green yellowish on flowering stage. The roots were adventitious, pale yellow in color. Leaves were slender, blade like, long, linear, tapering at both ends and glaucous moderate green in color. The inflorescence was large and the florets were arranged alternatively on the central axis. A spikelet consists of two bracts at the base called glumes. The glumes were placed one above the other on the opposite sides. The lower one is known as the first glume, while the higher one is known as the second glume. The flower is bisexual and floret was made up of two bracts, one on the outside called the lemma and the other on the inside called the palea. With regard to effect of organic manures, fertilizers and harvesting schedules on growth and yield , the results revealed that the combined application of Jeevamrit + NPK (60:45:45 kg/ha) gave the maximum value for plant height (87.00 cm), no. of leaves per plant (136.89), plant spread (70.87 cm2), fresh herbage weight per plant (262.32 g), dry herbage weight per plant (146.47 g), estimated fresh herbage yield (103.79 q/ha), estimated dry herbage yield (54.93 q/ha), essential oil content (0.50%), oil yield (52.45 l/ha). When plants were harvested after 90 days. Highest benefit cost ratio (1.57) was recorded with the application of treatment (jeevamrit + NPK) and minimum B:C ratio was recorded in T1 (0.10) i.e control.en_US
