Effect of consumption of herbicide, fungicide and nitrogen Fertilizer on contamination of soil, Water on rice, Shiroudcultivar

ABSTRACT: Efficient use and management of nitrogen and Chemical pesticides are important aspects of sustainable agricultural. Organic matter is relatively low in majority of soils in Iran, and continuous use of N fertilizer would create environmental hazards. The purpose of this study was investigating of chemical herbicides, fungicides, and nitrogen fertilizers on soil pollution and water on rice (Shiroudi cultivar). Treatments included two N level (0-250kg/ha), two herbiside level of Butachlor (0 - 3 lit/ha) and two fungicide level of tilt (0 - 1 lit/ha). The experiment was carried out in factorial manner in a completely randomized design with three replications. Treatments applied in rice and the residual effects were studied on seed yield and seed protein of rice and soil and water chemical characteristics after rice harvest. In general, field observations showed increasing rates of fertilizer increased grain yield and protein and the impact application of these rates of nitrogen fertilizers on water pollution and soil fields with such properties are dirt.
