¹ Above-ground part

The data of mungbean in this table means the total N and C content of mungbean. The data of oat in this table means the N and C derived from mungbean. Mungbean were labelled five weeks after planting and harvested at the beginning of pod setting and at maturity. Mungbean were divided into grain, stem, leaves and root, while oats were divided into above-ground part and root, and rhizodeposition.

The abbreviation in the table represent different treatments. S_p: sole mungbean harvested at pod setting, S_m: sole mungbean harvested at maturity, I_p: intercropping system harvested at mungbean pod setting, and I_m: intercropping system harvested at mungbean maturity. Values are means±standard error (n = 4). Values with different letters within a line indicate significant differences between the treatment S_p, I_p, S_m and I_m (Tukey HSD, p<0.05).
