Abstract

This study aimed to determine the ratooning ability of lowland rice to production management practices. It assessed the profitability of rice ratooning to the abovementioned objectives. The experiment was set out in a split-plot organized in a Randomized Complete Block Design with production management practices as the main plot and cutting heights of ratoon crop as the subplot treatment. Production management practices notably affected all agronomic characteristics, yield, and yield component parameters evaluated except the grain yield. Cutting height remarkably influenced all growth and yield parameters tested except panicle weight. Economic analysis revealed that the improved method achieved a higher gross margin (PHP21,321.60) than the farmer?s practice (PHP15,419.40) because of the former?s high productivity (1.64 t ha-1). A cutting height of 45.0 cm under the improved method obtained the highest gross margin (PHP28,677.00). Moreso, this approach is considered a good measure in adapting to the problematic scenario relative to climate change.
