Abstract

The yields of taro intercropped with Azolla and under slowly flowing water (F) and taro intercropped with Azolla after incorporation of Azolla into mud (B) were compared with N and P fertilization and a control in Mangaia, The Cook Islands. Significantly, higher yields were obtained for treatments F and B than for the chemical fertilization treatment, which had a minimal effect on yield. The control produced 53.4 and 64. 7% of yield of treatments F and B, respectively.
