Abstract: TPlants with nutrient deficiencies can not grow maximally and can even cause death. This study aims know to find out symptoms and the effect of deficiency elements of Nitrogen, Phosphorus, Potassium and Calcium in okra plants on growth. This study used a complete randomized design (RAL) consisting of 5 treatments and each treatment had 5 replications. The treatments consist of: Nutrition complete, without nitrogen (-N), without phosphorus (-P), without potassium (-K) and without Calcium (-Ca). The results of this study are the existence of significant differences in the treatment of nitrogen deficiency, phosphorus, potassium, and calcium. Treatment without nitrogen has a leaf color that tends to yellowish. Without phosphorus showing the color of yellowish green leaves, the tip of brown leaves like burning and dwarf leaves. Without potassium showing the color of yellowish leaves, leaves more wavy, the leaves dry and die. Without calcium showing the color of yellowish green leaves, withered leaves, brown leaf tip. Nitrogen, phosphorus, potassium and calcium deficiency affect plant height, leaf number, length and width of leaves, leaf color.
