Corn productivity of 5 soil series including Takhli, Lopburi, Thab Kwang, Wang Hai and Samo Thod was studies. Nine corn hybrids and one open-pollinated variety were tested for grain yield and agronomic traits under the soil series in 1998 early rainy season at farmer field to Tak fa, Nakhon Sawan Province. The experimental design used was a randomized complete block design with 4 replications. The result showed that an interaction between soil series and corn varieties was observed. There was significant difference between grain yield of corn grown on different soil series. Takhli, Lop Buri, and Thab Kwang series produced corn grain yield of 660, 666 and 635 kg/rai, respectively. Yield obtained from Wang Hai and Samo Thod series were varied because land was ununiformity and seed germination was poor. In comparison between all combinations of different soil series and corn varieties. Corn hybrid Pioneer 3013 grown in Takhli soil series produced the highest grain yield of 928 kg/rai. Takhli, Lop Buri and Thab Kwang series were suitable for Pioneer 3013 and CG 5445 because it produced high yield in those soils. Pioneer 3013 and CG 5445 gave high yield because it had good seed germination, high number of ear per plant high 100 seed weight, high number row per ear, high plant dry weight and high harvesting index.
