Research on the adaptation test of several sweet corn varieties has been conducted in irrigated rice fields of Rogo Village, South Dolo Sub-district, Sigi District, Central Sulawesi in the first season of bero. The objective of this research was to determine the adaptation of several adaptive sweet corn varieties with rice-rice-corn cropping patterns and favored by farmers. This research was design using a Randomized Block Design non Factorial consisting of 3 treatments of varieties and 4 replications. Corn varieties tested include Bonanza, Valentino, and Scada. The observations include plant height at harvest time, number of leaves, cob height, wet weight of cob with cornhusk, wet weight of cob without cornhusk, cob diameter, cob length, number of rows per cob, and wet weight of cobs per hectare. The result of statistical analysis showed significant effect on the parameters of the observation of the number of leaves, ear diameter, ear length, weight of cob without weight and corn productivity. From the three corn varieties tested, the best growth component wat the Bonanza varieties, but the yield results are still below than of the Valentino varieties.
