Optimal nitrogen (N) management is essential for profitable vegetable crop production and
to minimize N losses to the environment that are a consequence of an excessive N supply …

Food crisis is a matter of prime importance because it becomes more severe as the global
population grows. Among the solutions to this crisis, breeding is deemed one of the most …

Spectral reflectance data originating from Unmanned Aerial Vehicle (UAV) imagery is a
valuable tool to monitor plant nutrition, reduce nitrogen (N) application to real needs, thus …

Crop nitrogen status is a major issue for crop yield and quality. It is usually assessed by
destructive leaf or petiole tissue analysis. A quantitative nondestructive optical estimation of …

Efficient and accurate in-season diagnosis of crop nitrogen (N) status is crucially important
for precision N management. The main objective of this study was to develop a strategy for …

Measuring chlorophyll fluorescence is a direct and non-destructive way to monitor
vegetation. In this paper, the fluorescence retrieval methods from multiple scales, ranging …

Sustainable N management of intensive vegetable crops requires accurate and timely on-
farm assessment of crop N status. Proximal fluorescence-based sensors are promising tools …

A multiparametric optical sensor was used to nondestructively estimate phytochemical
compounds in white cabbage leaves directly in the field. An experimental site of 1980 white …

Precision nitrogen (N) management requires an accurate and timely in-season assessment
of crop N status. The proximal fluorescence sensor Multiplex® 3 is a promising tool for …

Monitoring plant nitrogen (N) in a timely way and accurately is critical for precision
fertilization. The imaging technology based on visible light is relatively inexpensive and …
