An experiment was conducted on plant okra for the period 2.3.2015 to 15.6.2015 in the canopy of the department of horticulture / faculty of agriculture / university of kufa to discuss the possibility of using aquatic plant (hornwort) fertilization and widespread in the euphrates river in the kufa city, compared with fertilizers of animal fertilizers (sheep only) and organic fertilizer (plant and animal residues winery) and composting (waste sheep + Poultry) is fermented as well as the treatment of control ,the cultivation of okra plant as furrow and watering using a drip irrigation system. The results showed significant superiority for the treatment of fertilization of hornwort compared to other treatments in most of the parameters of the plant (P, K, chlorophyll and plant height ) as well as reduce the salinity of the soil, which reached at the end of the season for the treatment of hornwort (0.75) Dessie Smenz.m -1 compared to treatments, which reached to (1.22 and 1.30 and 1.65 and 20.4) Dessie Smenz.m -1 for the treatments fertilization (organic waste composting and sheep + poultry and sheep and remnants of comparison) on respectively,. The yield was increasing in hornwort and organic treatments (6.920 and 6.343, and 3.428) tons. Ha-1 compared with yield of treatments ( remnants sheep + poultry and sheep and remnants of comparison) on respectively,. This is due to the high content of hornwort from elements (N, P K,), which reached to (4.15, 5.26 and 17.50) gm.kg -1 respectively. The results indicate the possibility of using hornwort plant which spread dramatically in the Iraqi freshwater and which has caused environmental disadvantages certified as fertilizer to the soil and this can be achieved one of the principles of sustainable agriculture.
