Ring
Figure 4-3. Ring number by dung application frequency interaction (P < 0.027) on herbage DM
harvested during 2006. Ring number effects were quadratic for three (P = 0.025)
applications, linear (P < 0.001) and quadratic (P = 0.008) for two applications, and
not significant for one (P > 0.370) or for zero applications (P > 0.100). Standard error
of a treatment mean was 106 kg ha-1. Ring Numbers 1 through 3 refer to sampling
areas 0 to 15, 15 to 30, and 30 to 45 cm from the center of the dung application,
respectively.
