The aim of this study was to determine the effects of nutrient supply and artificial defoliation on the growth rate of water hyacinth. The plants were subjected to two levels of nutrient (high and low) and three levels (0%, 10% and 80%) of defoliation treatment. The effect of the nutrient and repeated defoliation treatments was determined after six weeks. Ten percent defoliation did not show any significant difference from control plants in biomass allocation or relative growth rate (RGR) in either nutrient concentration, while 80% defoliation caused a significant decrease in the final RGR under high and low nutrient treatments. High nutrient treatment resulted in higher RGR and allocation to asexual reproduction, resulting in higher biomass accumulation compared to the low nutrient treatment, which had higher root growth and allocation to sexual reproduction. My data provide evidence that water hyacinth can fully compensate to low levels of defoliation.
