Nitrogen (N) is the most important nutrient in terms of quantity required to achieve high rice grain yields in southern NSW. The correct rate, timing and placement of N fertiliser enable efficient fertiliser use, high grain yield, water productivity and profitability.
Determining the amount of N to apply to a field is a complex decision with many interacting factors and few definitive answers. There is a balance between applying sufficient N to maximise yield potential and applying excess, which can increase the risk of lodging or reduce yield due to cold temperature sterility.
