Abstract
The field experiment was conducted during growing season 2011 at college of Agriculture and Forestry /Mosul University on water hyacinth Eichhornia crassipes (Mart)Solms to investigate seasonal growth habitat productivity horizontal shoot cover water and dispersal in Neniva province. Propagates had planted on 15-February -2011 in bonds which measuring horizontal weed mat growth on ( 1st April ,1st May ,1st June ,1st August) using plant high ,leaf area ,number and length of stolons . Randomize Complete Block Design with three replicates was used in a simple experiment .The results showed that water hyacinth had vertical growth relevant with plant high and leaf area which are more important in that growth especially at high temperature monthly (June, July ,august),while horizontal growth of mat was confirmed by increasing stolons length and daughter plant .Stolons length had increased more than doubled in August comparing growth in April . Also number of propagates had increased up to 127 in August comparing in April .On other hand ,the horizontal growth of weed mat had increased up to 92.7% in July . In general these characteristics gave a rapid growth rate that cover the water surface up to 4.20m length producing 728 daughter plant ,10.8m leaf area , 93 cm stolon length and 3743 leaf number during the period of study.
