Figure 1

Impact of crop management practices on CA performance, shown in 1-dimension partial dependence plot of the probability of yield gain as a function of precipitation balance (mm). The tick marks on the x-axis show the distributions of observations of precipitation balance in the dataset. ± SC indicates NT with/without soil cover. ± R indicates NT with/without rotation. ± F indicates NT or CA and CT with/without fertilization. ± WD indicates NT or CA and CT with/without weed and pest control. Plot a compares the productive performance of CA, NT+SC, and NT-SC. Plot b compares the productive performance of CA, NT+R, and NT-R. Plot c compares the productive performance of CA+F, CA-F, NT+F, and NT-F. Plot d compares the productive performance of CA+WD, CA-WD, NT+WD, and NT-WD. Plot e compares CA+Irrigation, CA-Irrigation, NT+irrigation, and NT-Irrigation. Plot f compares the productive performance of CA and NT in maize and winter maize systems.
