Abstract The objectives of the present study were to maximize the rice crop as follows : 1-Studying the effect of land levelling with different planting methods on growth, yield and yield components of rice, in addition to their effects on some physical properties. 2-Estimating water requirements and consumptive use of rice crop as well as use efficiencies and the effect of irrigation head on rice yield. 3-Assessment the effect of some non-traditional N fertilizers comparing with N-mineral fertilizer for creating new safe and healthy fertilizers to prevent more pollution assurance as well as saving a large amounts of mineral nitrogen fertilizers (optimizing fertilizer use), which could be realized using blue green algae mixed a moderate amount of mineral nitrogen fertilizer as a non traditional fertilizers for rice crop. |
