Abstract: Field experiment were conducted to assess the effect of different nitrogen levels on the growth and yield of garlic on clay loam soil. Eight nitrogen levels viz. 0, 50, 60, 70, 80, 90, 100 and 110kg nitrogen ha-1, respectively were tested. Results demonstrated that increasing nitrogen level up to 100kg ha-1 resulted in longer leaves (64.83), greater number of leaves per plant (17.90), maximum single bulb, weight (42.60g), and bulb yield per plant (7.08kg) and Bulb yield ha-1 (6746.03kg) . Further more, increase in nitrogen levels had no appreciable effect on the performance of garlic.
