The study was conducted to determine the adaptability trial of four varieties of sweet corn under Balibago, Magalang condition. It was conducted in Balibago, San Ildefonso, Magalang, Pampanga from May 2017 to July 2017. The four varieties used in the study are: T1 = sugar max F1; T2 = sugar king F1; T3 = sweet corn F1; T4 = rainy sweet F1. These treatments were arranged to experimental unit following the Randomized Complete Block Design (RCDB) with four replicates. Results revealed that no significant different on the plant height (cm) at 15, 30 and 60 days, number of leaves 15, 30 and 60 days, days to tasseling, length (cm) of corn ears 30, 60 DAP, fresh herbage weight/plot (kg) and computed yield tons per hectare. On the other hand, significantly different in terms of days to harvesting 70 DAP and diameter (cm) of corn ears 30, 60 DAP. With the aforementioned results, the author recommends that using other varieties to plant and consider the time of planting to come up the good adoptable variety to be planted under Balibago, Magalang condition. Further study in relation to adaptability trial using the other variety of sweet corn.
