title: [Growth of the water hyacinth (Eichhornia crassipes (Mart) Solms Laubach) in the tropics].
abstract: The growth and reproduction rates of water hyacinth (Eicchornia crassipes (Mart) Solms Laubach) in tropical areas, under natural and fertilized controlled conditions, were studied. The fertilizer used was swine fecal matter at three different levels: 1.25, 2.5 and 5%. The highest rate of growth was found with the 2.5% concentration, and this value was 49.16 g/m2/day on a dry-weight basis. Under natural conditions the rate of growth was 18.39 g/m2/day on a dry-weight basis. These results represent a yearly production in ton/ha among the highest reported in the world.
