Abstract
The goal of this paper was to investigate the strength of key spectral vegetation indices for the rice rotation effect related to the rice yield increment. Six widely used spectral indices were investigated in a study of the rice rotation effect in cotton-rice rotation and rice-rice monoculture in Xinghua, China. These six indices related closely with rice yield were investigated for cotton and rice during 2 years (2001 and 2002) on LANDSAT 7 ETM+images. Six rice vegetation indices of cotton-rice rotation were increased by an average of 6.28% (NDVI), 11.28% (GVI), 6.28% (SAVI), 1.25% (IPVI), 3.40% (RVI), and 7.66% (DVI) compared with that of rice-rice monoculture, respectively.
