| Abstract: | Near Infrared Spectroscopy (NIS) of HN1100 system was used to determinate crude protein in maize. The result showed that there was remarkable positive correlation between the prediction values and the chemical values. The correlation coefficients to chemical values in calibration set and validation set were 0.982 and 0.937, respectively. The standard error of calibration (SEC) was 0.124, and the error of validation (SEP) was 0.499. NIS can be used to determine crude protein in maize. |
