This fragrant grass is a versatile performer in the kitchen and is widely used in preparing beverages, soups, teas, herbal medicines and other dishes. Its stems are also used in teas, pickles and in flavouring marinades. The field experiment was carried out at the ACE farm of Field fresh Foods Pvt. Ltd, Ladhowal, Ludhiana during summer season 2013. The experimental treatments consisted of three level of irrigation (0.25, 0.50 and 0.75 IW: CPE ratio) with four rates of N application (0, 50, 100 and 150 kg.ha-1) with three replications. Irrigation levels were arranged in main plots and nitrogen application rates in sub plots. The effect of irrigation level on lemongrass, the level 0.75 was found significantly influenced the plant height, maximum 114.3cm and also maximum number of branches 45.8, number of stalk (42.9), stalk width (5.4 mm), weight of stalk (22.5 gm), stalk yield (4.6 q.ha-1). Effect of Nitrogen level on morphological characters of lemongrass, the nitrogen levels 150 kg.ha-1 was significantly influenced the lemon grass yield with the consistent and maximum plant height (1.22 cm), number of braches (47.7), number of stalk (43.3), stalk width (5.7 mm), stalk weight (23.4 gm) and maximum yield 4.7 q.ha-1 of lemongrass. The results of the present investigation on the effect of irrigation and nitrogen application on foliage growth and yield parameters, irrigation 0.75 IW + 150 kg N application was found statically superior over the rest treatments with maximum plant height 1.37.3 cm, whereas in case of number of branches and stalk, the 0.75 IW + 100 kg N application showed most efficient with maximum number of braches (52.3), number of stalk (46.7), stalk width (6.1 mm), stalk weight (25.0 gm) and 5.0 q.ha-1 of lemongrass yield and it was satirically at par with 0.50 IW + 100 kg N application.
