Abstract:

The maximisation of plant nitrogen-use-efficiency (NUE) has direct impact on increasing crop production, due to the increase of agronomic value of the fertiliser. Moreover, optimising the use of nitrogen will reduce the adverse effect on the environment that can be caused by nitrate leaching and nitrous oxide production. Accordingly, nitrogen (N) management in agriculture has been the focus of many researchers. Improvement of NUE can be achieved through measurement of the foliar N content of crops during growth. There are two classes of methods to diagnose foliar N status: destructive and non-destructive. Destructive methods are expensive and time-consuming as they require tissue sample collection and laboratory analysis. Non-destructive methods are rapid and less expensive, but usually less accurate. Improved accuracy is the goal of many researchers and various methods have been proposed that vary in complexity and optimality. This paper highlights non-destructive handheld methods to estimate foliar N status of plants.
