摘要: The strength of the associations cotton (Gossypium hirsutum L.) yield and N nutrition with integrated Normalized Difference Vegetation Index (NDVI) plant height measurements has been scarcely documented. objective this investigation was to compare in terms determination coefficient (R2) among leaf concentration respective NDVI taken at key growth stages. A field experiment carried out on no-till Jackson Milan Tennessee during 2008–2010. Six treatments 0, 45, 90, 135, 179, 224 kg N ha−1 were implemented a randomized complete block design four replicates for all site years. Regressions lint NDVI × plant NDVI + plant sometimes stronger than those alone. Associations similar or variably generally Utilization predict and/or assess variable advantages over use Both are more appropriate be used nutrition.
