FERTILIZER AND WATER EFFICIENCY IN CITRUSPLANTS USING FERTILIZER IRRIGATION MOBILECONTROL

. Citrus plants have a high growth response. Regular fertilization is needed to serve the high growth response. One of the important things in the cultivation of citrus plants is recognizing the need for fertilizers and water in accordance with the stages of growth of citrus plants Indonesian citrus farmers still rely on conventional fertilization and irrigation. They spreading fertilizer around the citrus plant and flush the water around it. This process of fertilization and irrigation needs more fertilizer and high cost because its need many labors to do it. This research proposes a system to control fertilization and irrigation automatically thus the farmers can reduce production costs.
