Abstract
Citrus plants have a high growth response. Therefore, regular fertilization is needed to serve the high growth response. Periodic fertilization is fertilizing which is carried out throughout the year at different intervals according to the needs of the orange plant. One thing that is important in the cultivation of citrus plants is recognizing the need for fertilizers in accordance with the stages of growth of citrus plants. Citrus farmers in Padang Rejo, Jember, East Java, Indonesia have been cultivating oranges for a long time but they still rely on conventional fertilization, which is to wait for rain on the grounds that if accompanied by rainwater, fertilizer will quickly absorb. However, if you wait for the rain to fall then if the time of fertilization has arrived but it does not rain, fertilization will be delayed so that the time of fertilization is not appropriate. Therefore, this paper proposes fertilizer irrigation mobile control for regulating fertilization and watering so that the use of fertilizer and water can be regulated and can be more efficient. So farmers can save on production costs, especially in the purchase of fertilizer and labor costs in watering supervision.
