Abstract

A split-split-plots experiment in a randomized complete block design with three replications was setup
to determine the impact of nitrogen fertilization on the physiological aspects (height, leaf area index (LAI),
number of leaves and number of suckers) of two improved taro cultivars (Samoa 1 and Samoa 2). Each replicate
contain two main plots (cultivars) which were split to accommodate three nitrogen rates (0, 100, 200 kg ha ). 1
These were further split to have five sampling dates (35, 70, 105, 140, 175 days after planting (DAP)). The data
collected from the experiment were analysed using the GenStat statistical software. The LAI, plant height,
number of leaves and suckers of Samoa 1 and Samoa 2 were increased during the early growth stages until 105
and 140 DAP before declining at 175 DAP. The difference in plant height, LAI, number of leaves and suckers
were highly significant (P<0.001) between the two cultivars during the five harvest dates (DAP). The difference
in plant height between the two cultivars was also significant (P = 0.04) as result of nitrogen fertilization.
Moreover, the difference in LAI between the two cultivars was significant (P = 0.003) as well. The results had
shown that there were significant differences between the two cultivars with regards to their physiological
aspects.
