Figure 1: NASA/POWER estimates vs observed values. (A) Relationship between NASA/POWER estimates and observed values (observed in Shenzhou) for daylight hours (n), rainfall precipitation (prec), relative humidity (rh), maximum air temperature (tmax), average air temperature (tmed), and minimum air temperature (tmin); (B) NASA/POWER vs observed values for accumulated rainfall in three different locations.

Figure 17: Ranks of 26 maize hybrids considering different weights for stability computed as the Wricke’s Ecovalence (Wi) and grain yielding (GY). The most-left ranks were obtained considering the stability only. The most right-ranks were obtained considering the grain yield only. Between the extremes, the ranks were obtained different weights for stability and yielding.
