Phytohormones influenced plant growth. While a lot of studies have been done on the
nutrients supplied into the fertigation system, there are lack of studies on the
effectiveness of plant hormone application along with the common nutrients supplied
for the development of plants. Therefore, the aim of this study is to identify the
presence of auxin hormone in seaweed and to compare the effectiveness of seaweed
and other type of fertilizers on the development of melon plant. Seaweed sample was
taken from Sabah and was dried. The seaweed extract solution was prepared and
then centrifuged. The Indole-3-acetic acid (IAA) in the sample was estimated by colour
test using Salkowski reagent. The highest development of melon in shoot elongation,
internote distance and the number of female flowers was achieved in the treatment
of seaweed extract containing IAA. Thus, it was proven that seaweed contains plant
hormones (IAA) that can improved the development of melon plant.
