Sandy soils in North Lombok are characterized by low organic matter, limited nutrient availability, and poor water-holding capacity, which constrain waxy maize productivity. This study evaluated a participatory bioameliorant-based intervention implemented through farmer training, hands-on practice, and field demonstration. Bioameliorant application markedly improved crop growth and yield compared with the control.
