3.1 Comparison of relative humidity between crop types
For every 20% increase in RH above papaya, taro and sweet potato increased by 19.85% and 19.84%, respectively, throughout the three-week period in 2014 (p < 0.001, see Figure 1); however, while the differences in RH are statistically significant, their magnitudes potentially fall within the measurement uncertainty of the sensor. We chose papaya as the control plant because it has the highest average canopy height. We observed many time points at which taro and sweet potato were 100% humid while the air was not fully saturated in the papaya field: 11% and 15% of the time, respectively.
