Functional Traits
Effect of water (W), nitrogen (N) and culture (C) individually and their interactions (W × N × C) had affected the functional traits (P<0.01, Table 2). CHI, and SLA were non-significantly affected by the interaction of W × N and W × C. Plant height and leaf nitrogen was not effective by C. The remaining other functional traits were affected significantly by each of the individual factors and their interaction (P<0.01, 0.05; Table 2). Plant height of WT and WC under flooding (F), nitrogen (N) and double additional nitrogen (2N) was non-significant under monoculture but significant under mixed culture. Flooding along with additional and double additional nitrogen (F.N, F.2N) promoted the plant height of WT compared with the WC both in monoculture and mixed cultures (Fig. 2a).
