The objective of this study was to compare the performance of two different remotely sensed
techniques in detecting the effects of terminal heat stress and N fertilization on final maize …

Maize crop production is constrained worldwide by nitrogen (N) availability and particularly
in poor tropical and subtropical soils. The development of affordable high-throughput crop …

Assessment of crop N requirements is necessary to develop production systems with optimal
N input. A field experiment with six maize (Zea mays L.) hybrids grown at three N fertilizer …

The growing use of commercial unmanned aerial vehicles (UAV) and the need to adjust N
fertilization rates in maize (Zea mays L.) currently constitute a key research issue. In this …

This paper presents a method for mapping the nitrogen (N) status in a maize field using
hyperspectral remote sensing imagery. An airborne survey was conducted with an AISA …

Accurately and timely diagnosis of plant nitrogen (N) status is imperative for N fertilization
management and yield prediction of summer maize. This study was aimed to identify the …

Remote sensing is an efficient tool to detect vegetation heterogeneity and dynamics of crop
development in real-time. In this study, the performance of three maize hybrids (Fornad FAO …

Maize yield has to be increased in the next decades in order to satisfy world demand. This
increase has to be achieved in a scenario of climate change particularly characterised by …

Vegetation indices (VIs) derived from active or passive sensors have been used for maize
growth monitoring and real-time nitrogen (N) management at field scale. In the present …

Rapid and non-destructive diagnostic tools to accurately assess crop nitrogen nutrition index
(NNI) are imperative for improving crop nitrogen (N) diagnosis and sustaining crop …
