Ratooning Response of Lowland Rice (Oryza sativa L.) var. PSB Rc22 to Production Management Practices

This study aimed to determine the ratooning ability of lowland rice production management practices. It assessed profitability abovementioned objectives. The experiment was set out in a split-plot organized Randomized Complete Block Design with practices as main plot and cutting heights ratoon crop subplot treatment. Production notably affected all agronomic characteristics, yield, yield component parameters evaluated except grain yield. Cutting height remarkably influenced growth tested panicle weight. Economic analysis revealed that improved method achieved higher gross margin (PHP21,321.60) than farmer’s practice (PHP15,419.40) because former’s high productivity (1.64 t ha <sup>-1</sup>). A 45.0 cm under obtained highest (PHP28,677.00). Moreso, this approach is considered good measure adapting problematic scenario relative climate change.
