Abstract: The introduction of noble garlic cultivars from South of the Brazil and Argentina in new regions, mostly due to the vernalization technique, contributed significantly for elevation in the productivity and quality of the garlic produced in Brazil. However, few are the studies aiming determine the nutritional requirements of vernalized garlic. The nitrogen present high influence in the elevation of the productivity and quality in garlic, being the molybdenum directly related to the assimilation and utilization this nutrient. The objective of this work was to evaluate the influence of different topdressing nitrogen doses and molybdenum doses applied by foliar dressing in the productivity of vernalized garlic originated from tissue culture. The experiment was installed under the experimental design of randomized blocks, in factorial scheme 5x4, being five doses of nitrogen (60, 90, 120, 150, and 180 kg ha-1) and four doses of molybdenum (0, 100, 200 and 300 g ha-1). The experiment was conducted under field conditions, with three replications. The bulbs of the cultivar Roxo Pérola de Caçador originated from tissue culture (four multiplications in field) used for planting were submitted to the vernalization by 50 days at 4ºC. The total and commercial productivities increased linearly with the topdressing nitrogen doses. No significant differences between the treatments were observed in relation to the index of secondary bulb growth. No response to the application of molybdenum doses by foliar dressing were verified, being some characteristics productive prejudiced with the application of this micronutrient.
