Moreover, to determine the efficiency (profitable) and effectiveness (effectiveness) of the use of these fertilizers on vegetable crops, including kale. For this reason, it is necessary to study further the use of inorganic fertilizers. The aim of the study was to determine the application of Urea fertilizer on the growth and yield of water spinach (Ipomoea reptans Poir). This research method used a randomized block design (RBD) consisting of seven (7) doses of urea fertilizer with three (3) replicates and two (2) sample plants. The placement of the urea fertilizer dose treatment in the experimental plots was carried out randomly.
