The NDVI was used to discriminate tobacco variety, assess fertilizer levels, and determine the impact of planting date on separating crops.
A split plot design with four planting dates, September, October, November, and December, as main plots, variety as subplot, and fertilizer treatments as sub-subplots was used.
Radiometric measurements were taken from 5 m × 5 m sampling plots, using a multispectral radiometer.
The September, October, and November crops had significant variety x fertilizer treatment differences (F<0.05) from the age of 10 weeks.
T 66 and KRK26 varieties had similar (F>0.05) NDVI values and these were greater (F<0.5) than those for K E1.
The 100% and the 150% fertilizer treatments were similar (F>0.05) and both were greater (F<0.05) than the 50% fertilizer treatments.
All of the fertilizer and variety treatments at the December planting dates had similar reflectance characteristics (P>0.05), which were lower (P<0.05) than the September and October planting dates.
The results showed that planting dates, varieties, and fertilizer levels could be distinguished using spectral data.
Weeks 10-11 and 15 after the start of the experiment were optimal for separating the planting date effect.
