Cauliflower is one of the most consumed vegetables, but its low production is a significant issue in Bangladesh. Cauliflower production may be declining due to a number of factors, including less frequently use of high-yielding color cultivars and inadequate nitrogen fertilizer dosages. The experiment was conducted at Regional Agricultural Research Station (RARS), Jamalpur, Bangladesh to assess the response of different nitrogen dose and cultivar on curd yield of cauliflower and to find out suitable combination for commercial production. Twelve treatments were tested including four nitrogen doses (0, 80, 100, 120 % RDN) and three cauliflower cultivars [Yellow cauliflower (Carotena), Purple cauliflower (Valentena) and white cauliflower (White Mountain)]. The results showed that, the highest curd yield (19.83 t ha-1) and highest MBCR (4.01) were obtained from treatment combination of (N100 x Yellow) which was significantly higher than control (N0 x White) combination (11.04 t ha-1). Moreover, application of 100% N registered the highest apparent gain in soil available N irrespective of cultivar response. Therefore, the combination of an optimum level of nitrogen (100 % RDN) and Yellow cauliflower cultivar (Carotena) may be recommended for the commercial production of cauliflower.
