Abstract
The ecological study of a typical taro farm at Sabana, Rota, Commonwealth of the Northern Mariana Islands (CNMI) was conducted from October, 1990 to June, 1991 to compare the pests associated with taro under low-input, high-input, and farmer's practice of weeding taro. This experiment was superimposed with a yield/profitability study of taro under weeding at 60 and 120 days after planting (OAP) (low input); 30, 60, 90, and 120 OAP (high input); and rototilling at 60 and 120 OAP (farmer's practice). Under the three weed management schemes, common diseases associated with taro were not observed during the experimental period. Only planthopper (Tarophagus proserpina) was consistently observed for eight months. Low-input plots had more counts of nymphs and adult planthoppers than other treated plots. Weed counting done at 60, 120, and 180 days showed 15 weed species as commonly growing with taro. However, Eleusine indica L., Ageratum conyzoides L., and Bidens pilosa L. were predominant and aggressively competing with taro for space, light, water, and nutrients.
