Abstract
Sweet corn (Zea mays saccharata Sturt) is a horticultural commodity also known as sweet corn. Sweet corn is popular among farmers because it has high nutritional content and can be harvested faster. However, national sweet corn production in 2020–2023 has decreased by 12.5%. The purpose of this study was to determine the interaction between nitrogen fertilizer type and planting distance on the growth and yield of NB SUPER F1 sweet corn. This study was a factorial experiment based on a randomized complete block design (RCBD) consisting of two factors. The first factor was the type of nitrogen fertilizer (N), which consisted of four treatment levels, and the second factor was the planting distance (J), which consisted of three treatment levels. The first factor was the type of nitrogen fertilizer (N), namely N0 = Urea 350 kg.ha-1 (control), N1 = Urea 200 kg.ha-1, N3 = KNO3 200 kg.ha-1. The second factor was J1 = 70 cm x 20 cm, J2 = 70 cm x 30 cm, and J3 = 70 cm x 40 cm. The results of the study showed an interaction between the combination of urea nitrogen fertilizer treatment at a dose of 200 kg.ha-1 and a planting distance of 70 x 40 cm on the parameter of ear weight with husks.
