(a) A handful of the water fern Azolla pinnata and mass propagation for aqueous Azolla extract preparation, (b) sweet corn plants on 9-week after planting showing the tassel of male inflorescence (top part) and ear of female inflorescence (middle part), (c) representative mature ear harvested on 10-week after planting from each respective treatment plant and (d) three randomly selected kernels from each treatment plant.
Mean value of growth parameters between treatments on sweet corn (a) Plant height, (b) stem diameter, (c) leaf area, and (d) chlorophyll content. The mean value with the same letter indicates no significant difference at p < 0.05.
The mean value of yield parameters between treatments on sweet corn (a) cob length, (b) total grains, (c) fresh weight of cob, and (d) weight of 100 grains. The mean value with the same letter indicates no significant difference at p < 0.05.
