Abstract: A system and method for in-field near infrared spectroscopy (NIRS) analysis of rubber and resin concentrations a guayule plant is provided. The system includes a wagon or other vehicle with the NIRS device mounted on the wagon. A computer or processor electrically coupled to the NIRS device is also housed within an area or extension of the wagon. During measurement of a guayule plant in the field, a guayule plant covering is placed over the guayule plant and a light shield coupled to the NIRS device is inserted into an opening on the guayule plant covering. The NIRS device is configured to perform a reading of the guayule plant within the plant covering and communicate results of the reading to the computer. A calibration equation is then preferably applied to the guayule plant readings to produce the rubber and resin concentrations of the guayule plant.
