Abstract Rubber is a new crop for the dry area of Thailand, northeastern region. This work was to evaluate the status of yield, nitrogen and phosphorus in rubber tree that planted in northeast Thailand. The experiment was conducted in the plantations of rubber tree clone RRIM600 and RRIT251. All plantations located in northeast region in 6 provinces which had a difference in annual rainfall: Loei (1,117 mm), Buriram (1,127 mm), Khon Kaen (1,368 mm), Sakhon Nakhon (1,375 mm), Udon Thani (1,443 mm) and NongKhai (2,029 mm). In each province, the 5 replicated plantations per clone were selected (Total plantation were 60 plantations). The results showed that the yield of rubber tree clone RRIT251 increased according to the annual rainfall, while the yield of RRIM600 had no relation. The leaf nitrogen content was not clearly related to both organic matter (O.M.) and rainfall, while the phosphorus in leaf had a strong relationship with the available phosphorus in the soil. The nitrogen (N) and phosphorus (P) contents in all plant parts (leaf, bark and dry rubber) were not significantly different between clones. The plot between yield and nutrients in leaf and dry rubber were characterized like an “upper envelope curve concept”. There is also a relationship between the N and P of the dry rubber and the leaves, so it is possible that the dry rubber standards can instead the standard of the leaf. The range of leaf nutrients were 1.73-2.79% in N and 0.20-0.35% in P, while the dry rubber N and P were 0.29-0.55% and 0.04-0.09%, respectively.
