摘要: Nitrogen (N) is the primary limiting factor to increase wheat ( Triticum aestivum L.) yield in Brazil and use of N fixing agents might be an alternative production. A field experiment was conducted 2006 Sao Paulo state, Brazil, with three rates (0, 60 120 kg ha -1 ) endophytic bacteria (IAC-HT-11; IAC-HT-8; IAC- AT-8) (1) evaluate their combined impact on biophysical (LAI grain yield) spectral parameters (NDVI, absorption band parameters) (2) determine that best correlated LAI yield. canopy reflectance measurements were made at jointing, heading ripening growth stages for this purpose. The statistical relationships between evaluated within among treatments. Statistical results showed significantly affected both as expected. Bacteria inoculation presented a significant effect only consistent reported literature. NDVI followed by PB AB 1205 nm provided estimates during stage indicating it may remote sensing based mapping.
