Abstract:
Sensors have become essential in farming. They have been allowing not only plant but also soil and climatically monitoring to support decision making to greater yields, as well as allowing rational use of inputs. Based on sensors, it is possible to develop efficient tools for the dynamics evaluating of crops directly in situ, including real-time analyzes. In this study, based on the use of sensors for red and the near-infrared lights spectra, the stress of rainfed maize crop was evaluated as a function of both Nitrogen dose and water availability. In fact, for validation, a truly crop dynamics stress was evaluated using the normalized difference vegetation index weighting by the value of the near infrared reflectance for each specific region of the agricultural field. Results have shown its relation with both plant water and Nitrogen availability. Furthermore, positive correlation with the plant stress and the modified vegetation index has been found, i.e., leading to an adequate indicator for plant stress and yield evaluation.
