ABSTRACT Weed control is consider the major obstacle for the growers in the organic farming. Lower plant productivity in organic farming mainly related to the poor weed control. It is widely known, in most cases, that losses caused by weeds exceeded the losses from any category of agricultural pests. Under water-stress condition, weeds can reduce crop yields more than 50% through moisture competition alone. In the light of the environmental and toxicological problems created by herbicides, it has become necessary to develop the safety methods for controlling weeds. Soil Solarization, Mulching, Biodegradable Mulch, Natural Herbicides, Hot Water, and Agronomic Practices have been successfully adopted in many countries as safe methods for controlling weeds in... |

ABSTRACT Water hyacinth (Eichhornia crassipes) is an oceanic macrophyte and one of the worst sea-going weeds in the world and Egypt. The grouping of substantial metals in water hyacinth was higher in roots than in shoots. Nutrient content e.g. ammonia, nitrate, nitrite and phosphate was higher in the shoots of water hyacinth. Water hyacinth is a wellspring of phytochemicals which have a medicinal function. In this study, the high degree of peroxidation and nonenzymatic antioxidant systems were detected in leaf extracts. The chemical analysis of the leaf extracts was performed using acetone, ethanol, methanol and n-Butyl alcohol. The fractionated extracts showed the presence of some medicine compounds that include phenols, protein, alkaloids, amino acids,... |
