More frequent applications of lesser amounts of fertilizer are suggested for rockdale soils. In general, fields that have not produced a crop of tannia or taro in the last 2 to 3 years are preferred. Avoid fields that have very high nematode populations. Bedding Plants are established in rows on flat land. During the cultivation process, ridges are formed down the rows of plants.
Ridges provide a place for storage organ formation, improve drainage and facilitate harvesting.
Cover Crops Cover crops are beneficial in crop rotation programs, but are not recommended immediately after tannia and taro production. Cultivation is needed after harvest to prevent feral plant establishment. Weed Management Tannia and taro are long-season crops. Control of weeds during roduction can be difficult. Early season competition of weeds is extremely critical and a major emphasis on control should be made during this period.
