Fig. 2: Quadratic relationships between drought severity and detrended cotton yield during the growing seasons for the 32 management systems.

From: Conservation agriculture increases the soil resilience and cotton yield stability in climate extremes of the southeast US

Fig. 2

The drought severity is represented by a standardized precipitation index (SPI) and b standardized precipitation evapotranspiration index (SPEI). The arched dashed line represents the relationship between mean cotton yield and drought severity. The shaded band around curves represent the 95% confidence limits.
