Possibilities of cereal canopy assessment by using the NDVI.
Original language description
The evaluation of canopy structure development of winter wheat (Triticum aestivum L.) and spring barley (Hordeum vulgare L.), and its spectral characteristics by means of the Normalised Difference Vegetation Index (NDVI) was performed in small plot fieldexperiments carried out at two locations within three years (2005 to 2007). Statistically significant effects of year, location, experimental treatment (i.e. a combination of seeding rate and nitrogen dose), and growth stage on values of NDVI were confirmed. Correlation analysis demonstrated that increased NDVI values indicated: a greater amount of biomass and its dry matter, above all in the period of stem elongation; a higher weight of plants, number of tillers per plant, and a number of plants per stand unit area in the period of tillering; a higher average weight of tillers and number of tillers per stand unit area at the beginning of stem elongation; a more intensive green colour of the stand, indicating higher supply of nitrogen.
