A method for irrigating and fertilizing rice using a sprinkler irrigation system. The method includes the steps of providing a sprinkler irrigation system, determining an amount of water to be applied to the rice, determining an amount of fertilizer to be applied to the rice, and applying the water and fertilizer to the rice through the sprinkler irrigation system. Depending upon rainfall, the irrigation water may be applied to the rice an average of about one to two times per week between its planting and emergence, about two to three times per week between its emergence and its panicle initiation stage, about three to five times per week between its panicle initiation stage and its initial ripening stage, and about three to four times per week between the rice's initial ripening stage and its harvest.

1. A method for irrigating and fertilizing rice using a sprinkler irrigation system, said method comprising the steps of: providing a sprinkler irrigation system;determining an amount of water to be applied to the rice based on external factors;determining an amount of fertilizer to be applied to the rice based on external factors;applying water to the rice through said sprinkler irrigation system wherein, between a combination of irrigation water and rainwater, the rice receives an average of between about 6 and 25 mm of water per week between its planting and its emergence from the soil's surface, an average of between about 13 and 75 mm of water per week between said emergence and its panicle initiation stage, an average of between about 19 and 102 mm of water per week between said panicle initiation stage and its initial ripening stage; andapplying a fertilizer to the rice through said sprinkler irrigation system. 2. The method of claim 1 wherein said sprinkler irrigation system is selected from one of a center pivot unit and a linear move unit. 3. The method of claim 2 wherein said sprinkler irrigation system is configured to minimize the application of water directly to a wheel track area. 4. The method of claim 3 wherein said sprinkler irrigation system includes rotator sprinkler units and the sprinkler units positioned adjacent drive units of said sprinkler irrigation system have a half-circle pattern. 5. The method of claim 3 wherein said sprinkler irrigation system includes at least one of a rotator sprinkler unit and a directional spray nozzle and at least one of said rotator sprinkler unit and directional spray nozzle is mounted to a boom-back adjacent a drive unit of said sprinkler irrigation system. 6. The method of claim 1 wherein the amount of water applied to the rice is dependent upon climatic conditions, crop growth stage, soil moisture content and rainfall. 7. The method of claim 1 wherein between the combination of irrigation water and rainwater, the rice receives an average of between about 13 and 89 mm of water per week between said initial ripening stage and its harvest. 8. The method of claim 1 wherein the water is applied to the rice about one to two times per week between said planting and said emergence, about two to three times per week between said emergence and said panicle initiation stage, and about three to five times per week between said panicle initiation stage and said initial ripening stage. 9. The method of claim 1 wherein applications of between about 6 and 13 mm of water are applied to the rice one to two times per week between said planting and said emergence, applications of between about 6 and 19 mm are applied two to three times per week between said emergence and said panicle initiation stage, applications of between about 6 and 19 mm are applied three to five times per week between said panicle initiation stage and said initial ripening stage. 10. The method of claim 1 wherein a portion of said fertilizer is applied in a substantially dry form prior to emergence of the rice and a portion of said fertilizer is applied in a suspension form after emergence of the rice. 11. The method of claim 1 wherein a portion of said fertilizer is applied in a substantially dry form prior to emergence of the rice and a portion of said fertilizer is applied in a liquid form after emergence of the rice. 12. The method of claim 1 wherein said fertilizer contains nitrogen, major nutrients and micronutrients. 13. The method of claim 12 wherein between about 20-40% of the total amount nitrogen is applied at a time in close proximity with the planting of the rice and between about 60-80% of the total amount of nitrogen is applied after the planting of the rice in one of a liquid form and a suspension form through said sprinkler irrigation system. 14. The method of claim 1 further including the step of applying a pesticide. 15. The method of claim 14 wherein said pesticide is a herbicide. 16. The method of claim 15 wherein a portion of said herbicide is applied prior to emergence of the rice and a portion of said herbicide is applied after emergence of the rice. 17. The method of claim 14 wherein said pesticide is a fungicide and is applied as needed from an early boot stage through a 10% heading stage. 18. The method of claim 1 wherein said external factors include at least one of soil type, soil moisture conditions, soil fertility conditions, type of rice, and average rainfall during the rice's growing season. 19. The method of claim 1 further including the step of selecting a type of rice seed. 20. The method of claim 19 wherein said type of rice seed is selected from at least one of a hybrid and a variety. 21. The method of claim 20 wherein said hybrid and variety have blast resistant and aggressive rooting and tillering characteristics. 22. The method of claim 19 wherein the rice is seeded at a rate between approximately 28 and 180 kg/hectare, dependent upon whether rice is a hybrid or variety. 23. The method of claim 19 wherein said rice seed is drilled. 24. A method for irrigating and fertilizing rice using a sprinkler irrigation system, said method comprising the steps of: providing a sprinkler irrigation system;determining an amount of water to be applied to the rice based on external factors;determining an amount of fertilizer to be applied to the rice based on external factors;applying water to the rice through said sprinkler irrigation system wherein, between the combination of irrigation water and rainwater, the rice receives an average of between about 6 and 25 mm of water per week between its planting and its emergence from the soil's surface, an average of between about 13 and 75 mm of water per week between said emergence and its flag leaf stage, an average of between about 19 and 102 mm of water per week between said flag leaf stage and its panicle emergence stage, and an average of between about 13 and 89 mm of water per week between said panicle emergence stage and its maturity; andapplying a fertilizer to the rice through said sprinkler irrigation system. 25. A method for growing rice using a sprinkler irrigation system, said method comprising the steps of: providing a sprinkler irrigation system including rotating sprinkler units, wherein said sprinkler units positioned adjacent drive units of said sprinkler irrigation system have a half-circle pattern;determining an amount of water to be applied to the rice based on external factors;determining an amount of fertilizer to be applied to the rice based on external factors;applying water to the rice through said sprinkler irrigation system wherein, subject to rainfall, applications of between about 6 and 13 mm of water are applied to the rice one to two times per week between its planting and its emergence from the soil's surface, applications of between about 6 and 19 mm are applied two to three times per week between said emergence and a panicle initiation stage, and applications of between about 6 and 19 mm are applied three to five times per week between said panicle initiation stage and a initial ripening stage; andapplying a fertilizer to the rice through said sprinkler irrigation system. 26. The method of claim 25 wherein subject to rainfall, applications of between about 6 and 19 mm of water are applied two to four times per week between said initial ripening stage and the rice's harvest.
