<![CDATA[Waxy corn (Zea mays ceratina L.), has a high amylopectin content, resulting in a soft and sticky texture and showing strong potential as a local food source. Its development requires the selection of varieties that are well adapted to specific agroecosystem conditions, such as those in Lhokseumawe. This study aimed to evaluate the growth and yield and to determine the best adaptability and highest-yielding varieties of waxy corn under the agroecosystem conditions of Lhokseumawe. The experiment was conducted using a single-factor Randomized Block Design (RBD) with three replications. The treatment factor was variety (V), consisting of Arumba (V1), Kumala (V2), Rasanya (V3), Jutawan (V4), Jantan (V5), Paramita (V6), URI 1 (V7), and Pandu (V8). The results showed differences in the growth of several waxy corn varieties under the agroecosystem conditions of Lhokseumawe, particularly in plant height at 4 and 8 weeks after planting (WAP), stem diameter at 4 and 6 WAP, and number of leaves at 6 and 8 WAP. Different varieties also showed significant differences in several yield components, including days to male flowering, days to female flowering, total soluble solids, cob diameter without husk, cob weight without husk per plot, and yield. The Jutawan variety showed the best adaptability and the highest yield potential. This was indicated by optimal plant height and stem diameter, supported by superior yield components, like a cob weight without husk per plot of 7,572.4 g, total soluble solids of 18.20 °Brix, and yield reaching 12.62 t/ha.]]>
