Prediction of Canola Residue Characteristics Using Near-Infrared Spectroscopy

Table 5

Pearson correlation coefficients for residue traits of canola plant components measured using laboratory reference methods and compared to NIRS predicted values across all years, locations, and canola types. For each pair, the level of significance was <0.0001 at .
