Significant differences between specified treatments at , 0.05, 0.01, or 0.001, respectively. NS: no significant difference at for the specified contrast. aMM: mill mud; CP: yard waste compost. Treatments 2 and 3 were broadcast prior to planting and treatments 4–9 were applied in the furrow prior to planting. bOther contrasts tested in analysis of variance were treatments 1 versus 4, 5, and 6; 4 versus 5; 5 versus 6; and 7 versus 8. Only contrasts with significant differences were listed in the table. |
