Waterlogging, by restricting the amount of oxygen available in the root zone, significantly disrupts the growth, physiology, and productivity of capia pepper, a crop highly valued for its economic and nutritional importance. This study examined the effects of varying waterlogging durations (2, 4, 6, 8, and 10 days) applied at three different growth stages (vegetative, flowering, and fruiting) on the yield and quality parameters of capia pepper (Capsicum annuum L.). The findings showed that increasing waterlogging duration significantly decreased yield, plant height, fruit number, fruit length, and fruit flesh thickness by 74.1, 55, 75.4, 63.2, and 26.6%, respectively, relative to the control. Among the growth stages, plants were more vulnerable to waterlogging during the flowering stage, where waterlogging for more than two days caused a total yield loss. On the other hand, waterlogging at the fruiting stage had less effect on the yield and other growth parameters. Similarly, under waterlogging conditions, SPAD chlorophyll index and stomatal conductance decreased by 68.9 and 87.7%, respectively, alongside significant reductions in leaf potassium (K) and calcium (Ca) levels. These findings show that capia pepper is highly sensitive to waterlogging during the flowering stage. The study also reveals that farmers should prioritise adequate drainage and irrigation during flowering in areas where capia pepper is cultivated.
