Fig. 1. Effects on yield per plant, effective yield per plant, number of tubers per plant and infection rate of tuber in irrigation and drought rotation
A: effects of yield level per plant from irrigation and drought rotation; B: effects of effective yield level per plant from irrigation and drought rotation; C: effects of number of tubers per plant from irrigation and drought rotation; D: effects of infection rate of tuber from irrigation and drought rotation. Q9: Qingshu 9; H88: Cooperation 88; L6: Lishu 6. Different lowercase letters indicate significantly different among treatments at P < 0.05. The results are the averages of the second and fourth crops.
