This research aimed at determining the electromagnetic reflectance of winter crops throughout their growth and development under two soil management systems. The field experiment was carried at Embrapa Trigo, Passo Fundo, state of Rio Grande do Sul, by taking nine measurements with a spectral radiometer under two types of soil management (no-tillage and conventional soil tillage) on three winter species (wheat, white oat and common vetch) employed in crop rotation systems. Observed values on the six treatments on every measurement followed the typical standard and characteristics of the vegetation. The observed reflectance in the visible range was low, with a peak around 550 nm a steep increase around 730 nm and was maintained high in all the near infrared region. No-tillage presented a higher reflectance in the visible and infrared range. Oat presented higher reflectance in the infrared range than the other crops. Results indicated that the analysis of the reflectance of a canopy can be used as a good indicator of the changes that occur in the vegetation during their cycle and also can be used to differentiate between species aiming at monitoring crops. |
