Improving Nitrogen Use Efficiency in Cereal Grain Production with Optical Sensing and Variable Rate Application

TL;DR: In this article, the validity of using in-season estimates of grain yield (INSEY) and a response index (RI) to modulate N at 1-m 2 spatial resolution was evaluated.
Journal ArticleDOI

In-Season Prediction of Potential Grain Yield in Winter Wheat Using Canopy Reflectance

TL;DR: In this paper, the potential grain yield of winter wheat (Triticum aestivum L) was predicted using in-season spectral measurements collected between January and March, where the normalized difference vegetation index (NDVI) was determined from reflectance measurements under daytime lighting in the red and near-infrared (NIR) regions of the spectra.
Journal ArticleDOI

Use of Spectral Radiance for Correcting In-season Fertilizer Nitrogen Deficiencies in Winter Wheat

TL;DR: In this paper, spectral radiance readings for red and near-infrared (NIR) wavelengths were obtained in wheat between Feekes physiological stages 4 and 6 using photodiode-based sensors fitted with interference filters.
Journal ArticleDOI

Optical Sensor‐Based Algorithm for Crop Nitrogen Fertilization

TL;DR: The WheatN.1.0 algorithm as discussed by the authors combines some of the current concepts for N management in cereal production into an applied algorithm. But it does not follow any kind of generalized methodology that guarantees maximum nitrogen use efficiency (NUE).
Journal ArticleDOI

Nitrogen fertilization optimization algorithm based on in-season estimates of yield and plant nitrogen uptake

TL;DR: In this article, an alternative method of determining fertilizer N rates using estimates of early-season plant N uptake and potential yield determined from in-season spectral measurements collected between January and April.
