Other claims from this paper (7)
- Intervention effect Lettuce yield, growth parameters, and nitrogen content differed by fertilizer amount.
- Method / resource The NDVI yield regression had R2 of 0.87.
- Method / resource The NDVI total nitrogen regression had R2 of 0.77.
- Intervention effect Flooded lettuce had lower yield than non-flooded lettuce under standard fertilization.
- Intervention effect Flooded lettuce had lower growth parameters than non-flooded lettuce under standard fertilization.
- Intervention effect Waterlogged treatments had values comparable to non-flooded treatments without fertilizer.
- Method / resource The authors conclude early heading drone NDVI can diagnose growth and estimate lettuce yield with nitrogen status.
