Figure 1

Responses of taro plants to NPK fertilizer application in morphologically altered plants (A and C) and with different planting materials (B and D). The standard errors are represented by the length of the error bars. MAM, morphological alteration involving excision of the mother plant; MAS, morphological alteration involving removal of all suckers; NMA, non-treated control; PMC, planting material cormel; PMS2, planting material suckers with two leaves; PMS4, planting material suckers with four leaves; SPAD, unit-less indicator for leaf chlorophyll content. Small letters a, b, and c on tops of the SPAD value bars were used to indicate differences amongst the morphological alteration treatments.

Dry weights of leaf blade, petiole and fibrous roots of the individual mother plant (A, C and E) and suckers (B, D and F) cultivated using cormel (PMC) or seedling with two (PMS2) or four (PMS4) leaves observed at 12 WAP, 20 WAP and 28 WAP in taro plants. The standard errors are represented by the length of the error bars. MP, mother plant; SK, sucker; WAP, weeks after planting.

Figure 5

Number of suckers and total number of leaves per plant were higher in plants grown using cormel as the planting material (A, C) and the number of suckers and leaves were not different between the mother plant excision treatment and the non-treated plant (B, D), when observed at 12 WAP, 20 WAP and 28 WAP in taro plants.
