CTMR and CTTR vs. CTNRsignificant · Five harvests, June 2014-2018 · Quirinópolis · Clayey soil. CTMR and CTTR variants separately versus same-tillage no-removal CTNR. Results p.7 explicitly identifies CTMR, CTTR and RTTR as lower than the other treatments; the six-treatment design identifies those others as CTNR, RTNR and RTMR. CTNR is the same-tillage reference chosen here. Figure 9 contains marginal averages only and supplies no combination-specific means or tests. Supplementary Table S1 is unavailable; significance rests solely on the explicit Results comparison, with no numerical observations.

RTTR vs. RTNRsignificant · Five harvests, June 2014-2018 · Quirinópolis · Clayey soil, RTTR versus same-tillage no-removal RTNR. Results p.7 explicitly identifies RTTR among the treatments yielding less than the remaining treatments, which the six-treatment design identifies as CTNR, RTNR and RTMR. RTNR is the same-tillage reference chosen here. This preserves the abstract's RTTR headline separately from CT removal because the paper reports different moderate-removal outcomes under CT and RT. Figure 9 shows marginal averages only; Supplementary Table S1 is unavailable. No combination means or inferred chart tests; significance rests on the explicit Results comparison.
