Summary of yield resilience of tomato (a) and maize (b) in the conventional maize-tomato system (CONV), maize-tomato system with winter cover crops system (CONV + WCC), and organic maize-tomato system (ORG). Solid lines = CONV; dotted lines = CONV + WCC; and long-dashed lines = ORG. Values represent the ratio of the performance of target system relative to the maximum across three systems. Yield stability is the average ratio of four stability metrics (see Table 1). Yield resistance is the ratio of minimum yield potential (see Table 2).
