Influence of Diurnal Irradiance Variation on Chlorophyll Values in Wheat: A Comparative Study Using Different Chlorophyll Meters

The canopy greenness, a visible indicator of crop nitrogen content, photosynthetic efficiency and overall crop health status is directly influenced by chlorophyll content. A lot of ambiguity exists over use of available chlorophyll meters and proper time of measurement during the day. In order to find differences between chlorophyll meters and the effect of diurnal variation of irradiance on chlorophyll measurements, three different chlorophyll...
