Wheat Analysis

Using a field spectroradiometer for wheat crop analysis

NIR spectroscopy can be used to provide critical information on wheat crop health and growth in the field. Measurements taken of a wheat canopy during different growth stages can reveal data on protein, lignin, cellulose, water, sugar, starch, chlorophyll content and more.

Using a PSR-1100f in the field, a researcher can gain information for wheat trait selection, estimation of crop yield, crop stress, and identification and control of crop pests.

An NIR agricultural spectroradiometer provides fast, easy-to-use and non-destructive methods for characterizing wheat samples. A researcher can analyze the spectra data collected to:

  • Determine the photosynthetic activity of a crop canopy
  • Measure crop health and growth at various stages
  • Estimate potential grain yield
  • Monitor plant stress through chlorophyll content measurement
  • Check for nutrient deficiencies or over fertilization
  • Check moisture content and fine-tune irrigation practices

The PSR-1100f is a handheld spectroradiometer with the following features:

  • 320-1100nm spectral range
  • Rugged anodized aluminum construction for field reliability
  • High resolution and high sensitivity
  • Keypad, LCD display, and on-board storage for 2500 scans
  • One-touch operation with auto-exposure, auto-dark current, and auto-shutter
  • Compact and lightweight unit
  • Snap-in rechargeable battery
  • Easy to use DARWin SP Data Acquisition software that saves scans as ASCII files for further analysis with other software packages
  • Access within DARWin SP to 19 vegetation indices
