This pot experiment was conducted at Narathiwat Animal Nutrition Research Center, Narathiwat Province to evaluated plant nutrient status for Paspalum atratum grown in Ban Thon (Bh) and Tha Sae (Te) soil series using the Omission trial technique arranged in Randomized Complete Block Design with 4 replication and 16 treatments for each soil series with nutrient rates being : 16, 6.4, 16, 6.4, 4, 4, 0.8, 0.8, 0.08, 0.64, 0.48 and 0.08 kg/rai (All) for N, P, K, Ca, Mg, S, Mn, Fe, B, Zn, Cu, and Mo respectively, four experimental rates with Control 1/2 All, All and 2 All were used. Grass was cut at ground level at 60 days after planting. The experimental result for dry matter yield of Atratum grass in Ban Thon soil and The Sae soil were response at 2All. In Ban thon soil was found to be severe deficiency in N and P with leaser degree for Cu. Also severe deficiency in P was observed in Tha Sae soil but less severe for N and K. In Ban Thon soil, the N application for Atratum grass at 2All (32 kg N/rai) showed nitrogen content lower than standard level, but the P and Cu application at 2All (12.8 kg P/rai and 0.48 kg Cu/rai) showed potassium and cupper content at standard level. In Tha Sae soil, the N and K application for Atratum grass at 2All (32 kg N/rai and 32 kg K/rai) showed nitrogen and potassium content at standard level, but the P application at 2All (12.8 kg P/rai) showed nitrogen content lower than standard level.
