ABSTRACT
Sargassum sp. was mechanically processed and utilized as fertilizer for Zea mays with four different levels of treatments: control, 10 g, 20 g and 30 g. Growth activity was measured in terms of fresh- weight and plant height. There were three replicates for every treatment.
There was significant difference in the plant height readings for each week during the three weeks experimentation. However the control produced the highest yield, instead of the expected treatment 3. The only weight reading also expressed significant difference among the four treatments.
Based on the difference in plant height between the first and second week after planting, the control and treatment 1 are non-inhibitory; treatments 2 and 3 are inhibitory; between the second and third week; the control, treatments 1 and 2 are non-inhibitory while on the treatment 3 was inhibitory.
