The influence of nitrogen levels on growth and bulb yield of two garlic cultivars

Garlic belongs to family Alliaceae is one of the oldest cultivated vegetables and important medicinal plant. Fertilization of this plant has a critical role in growth and bulb yield. The investigation was carried out by application of nitrogen (0, 25, 50, 75, 100 and 125 kg/h) as main factor and garlic cultivar (“Hamedan” and “Violet”) as minor factor in a split plot experiment based on randomized complete block design (RCBD) with three replications in Firoozabad, Fars Province, Iran. The results revealed that nitrogen levels and type of the cultivar altered growth characteristics and bulb yield. Bulb yield was maximum at 100 Kg N/ha which was not significantly different when compared to 50, 75 and 125 Kg N/ha. The bulb yield was the maximum in cultivar “Violet”.
