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 …

Maize is the most cultivated cereal in Africa in terms of land area and production, but low soil
nitrogen availability often constrains yields. Developing new maize varieties with high and …

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 …

Under ideal conditions of nitrogen (N), maize (Zea mays L.) can grow to its full potential,
reaching maximum plant height (PH). As a rapid and nondestructive approach, the analysis …

Determining a precise nitrogen fertilizer requirement for maize in a particular field and year
has proven to be a challenge due to the complexity of the nitrogen inputs, transformations …

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 …

In recent decades, many spectral indices have been proposed to estimate crop nitrogen (N)
status parameters. However, most of the indices based on red radiation lose their sensitivity …

Low soil fertility is one of the factors most limiting agricultural production, with phosphorus
deficiency being among the main factors, particularly in developing countries. To deal with …

Satellite remote sensing has not been practical for agronomic research conducted using
small plots due to spatial resolution issues. The objectives were to determine,(1) the …

Remote‐sensing data acquired by satellite have a wide scope for agricultural applications
owing to their synoptic and repetitive coverage. On the one hand, spectral indices deduced …
