A field study on fertigation of cauliflower (Brassica Oleracea var. botrytis) using drip irrigation system was undertaken with comparing two varieties which were Fl Hybrid 882 cultivar and Fl Hybrid 307 cultivar. Fertilizer application (1.5 to 1.6) and 7 minutes water drip every 2 hours when plant exceeds week six. This research using netted rain shelter/greenhouse complete with fan pad cooled, irrigation system and cauliflower was planted by using cocopeat/soilmix system which replaced soil. There are two parameters were taken. (1) Growth parameter and (2) yield parameter. For growth parameter divided into (a) number of leaves, (b) height of plant and (c) diameter of stem. While yield parameter consists of (a) diameter of cauliflower and (b) weight of cauliflower. From this field of study Fl Hybrid 882 variety showed a good yield compared to F1 Hybrid 307.
