Abstract: This report summarizes the results of a single experiment in determining the phosphorus requirement for Chinese taro. Based upon the predicted results, 3,571 lbs treble superphosphate gave the highest no.1 and marketable corm yields. The maximum predicted net revenue of marketable corms,
$13,608, was attained at 3,061 lbs of treble superphosphate per acre. This was a 20 percent increase in net revenue as compared to applying no treble superphosphate. For Hilo soils with approximately 46 ppm available phosphorus, the preliminary recommendation for treble superphosphate is 3,061 lbs per 14,520 plants per acre as a pre-plant application.
