The experiment of tableted NPK fertilizer of rotation planting of upland rice kidney bean-corn on ultisols Jatinangor was carried out from January 1996 until February 1997. The aim of this experiment was to study the effect of combination of dosage and form of tableted NPK fertilizer to some soil chemical properties, growth and yield of rotation planting of upland rice-kidney bean-corn on Ultisol Jatinangor. Beside that this experiment also wanted to know the best form and dosage combination for increasing yield of rotation planting. The design used were Randomized Block Design consisted of 6 combinations of form and dosage of tableted NPK fertilizer, with 5 replications. The levels of tableted NPK fertilizer were 100 percent, 86 percent, 80 percent, 65 percent, 50 percent and 35 percent of recommended dosage for each plants. The result of the experiment showed that: (1) The combination of form and dosage of tableted NPK fertilizer affected only for available P after upland rice; (2) the combination of form and dosage of tableted NPK fertilizer affected growth of all the test plants; and (3) the combination of form and dosage of tableted NPK fertilizer affected yield of upland rice only, and the best combination is tableted NPK fertilizer and 65 percent recommended dosage
