ABSTRACT
This study, conducted from October 2023 to March 2024 in Labrador, Buug, Zamboanga Sibugay, assessed the impact of jicama intercropping schemes on sweet corn growth and yield under regenerative farming. A 565 m² area was arranged using a Randomized Complete Block Design with four treatments (T1–T4), each replicated four times. Treatments varied in jicama spacing using the quincunx method. T1 (jicama between every corn row) consistently outperformed other setups in plant height, stalk circumference, and corn ear weight and size. While T4 produced the longest ears, it had lower overall yield. Statistical analysis confirmed significant differences among treatments. T1 is recommended as an effective strategy to boost sweet corn productivity in sustainable farming systems.
