Effects of patch position (NE-SW vs. NW-SE patches) on the growth of Bolboschoenus planiculmis under each of the five treatments.

F-values, degree of freedoms and P-values are based on linear contrasts between the NE-SW and NW-SE patches. C, HL, HH, PL and PH represent the homogeneous treatment with no competitors, homogeneous treatment with competitors of low density, homogeneous treatment with competitors of high density, patchy treatment with competitors of low density, and patchy treatment with competitors of high density, respectively.
