The yield gap was decomposed into efficiency, resource and technology yield gaps. Rice yield gap in Central Luzon was 3.8 and 4.8 ton ha−1 in the wet and dry season. Technology yield gap explained half of the yield gap in both seasons. Efficiency and resource yield gap each explain a quarter of the yield gap in dry season. Resource yield gap was larger than efficiency yield gap in the wet season.
