Abstract
The current study was conducted in the Glass House at the Faculty of Education for Women of the University of Kufa to test the biological activity of the Oryza Sativa L. residues against Triticum Estivum L., Hordeum Distichum L., andZea Mays L.The study also aims to examine if this toxicity is behind the decline of growth and germination of the cultivated plants after the rice had directly been harvested in the same field. The study included the glass house experiment, which is the cultivation of grains of (wheat, barley and corn) in plastic pots after treatment with the rice extract in the same concentrations (0.20, 40, 60). The results indicated that the rice residues reduced the growth of vegetative plants of wheat and barley and corn, and a decrease in the germination percentage and rate of germination parameters when the concentration increased to 60%.
