Intercropping Cedrela odorata with Shrubby Crop Species to Reduce Infestation with Hypsipyla grandella and Improve the Quality of Timber

Table 2

Height, root collar diameter, survival per plot, and rate of forked or multiple stem trees per plot (bad quality) of C. odorata, 24 months after planting in pure forest plantations (FP) or combined with intercrops (for abbreviations see Table 1). Standard deviations are given in brackets. Different letters within columns denote significant differences between treatments (P < 0.05 based on LSD test for height and diameter and Wald confidence intervals for survival and bad quality rate, respectively).
