SURVEY OF FACTORS (SODIUM CHLORIDE, ACID ACETIC, SHADOW, CUTTING) AFFECT TO THE SPREADING OF WATER HYACINTH EICHHORNIA CRASSIPES (MART.) SOLMS

<p><strong>ABSTRACT: </strong></p><p>Water hyacinthEichhornia crassipes (Mart.) Solms is a weed species that causes a lot of harm to the environment and humans. Treatment of sodium chloride (salt),acid acetic, shadow or cutting is applied effectively in spreading of Eichhornia crassipes (Mart.) Solms. Sodium chloride 3%  control widespread of Eichhornia crassipes (Mart.) Solms and shadow reduces the number of shoots and leaves stronger than acetic acid 5% and  sodium chloride 3%, and  acetic acid 5% caused leaf damage more strongly than sodium chloride 3%. Other while, if stolon is cut each week, the shoots and the stolon will reappear each week after cutting, but could not appear at week 6.</p><p> </p><p><i><strong>Keywords: water hyacinth Eichhornia crassipes (Mart.)
