The objective of this experiment was to develop the rapid method for estimating crude protein content of king grass (Pennisetum purpupoides) and segnal grass (Brachiaria humidicola) using SPAD cholofil meter and leaf color chart. The study was arranged in a completely randomized design with four treatments and five replications. The two species grass were fertilized with difrent level of urea were PO (0 kg N ha-1/control), P1 (60 kg N ha-1), P2(120 kg N ha-1) and P3(180 kg N ha-1). Parameters observed were crude protein content, leaf color and chorophil. The result showed that fertilization significanly effect crude protein, leaf color and chlorofil countent of leaf. Leaf color chart, chlorofil countent of leaf and crude protein have an positif corelation with the increasing of urea level.
