Abstract

This study aimed to determine the ratooning response of lowland rice variety NSIC Rc216 to cutting strategies of ratoon crops. This determines the appropriate cutting strategy that produces a higher ratoon yield. It evaluates the profitability of rice ratooning following the cutting strategy adopted. The experiment was laid out in a Randomized Complete Block Design with cutting procedures as the treatments. The cutting strategy significantly affected the number of days from harvesting the primary crop to harvesting the ratoon crop, stem elongation, panicle length, and grain yield (t ha-1). In contrast, it did not remarkably influence the panicle weight and percent filled grains of ratoon crops. The results revealed that shorter cutting height (7.5cm) significantly prolonged the maturity of ratoon crops (80.33 days), elongated longer stem (97.17cm), longer panicle length (28.23cm) that eventually produced higher grain yield (1.35 t ha-1) compared to 30cm cutting height. The harvesting of panicles only remarkably achieved a higher grain yield (1.50 t ha-1) compared to those ratoon plants with cutting heights of 30.0cm (0.67 t ha-1) but comparable to ratoon plants with 60.0cm and 7.5cm cutting heights which produced higher grain yields of 1.48 t ha-1and 1.35 t ha-1, respectively. Economic analysis revealed that the harvesting of panicles only and cutting height of 60.0 cm showed a higher gross margin of 274.09 and 267.13 US Dollars, respectively, because of higher productivity levels of said treatments. These strategies are adequate measures in solving the problems of rice self-insufficiency situation due to the climate change situation.
