SUCKERS ACQUISITION AND PREPARATION
Local farmers supplied both Giant French and False Horn suckers which were detached from the mother plant when they have attained a height of about 20cm. The suckers were cleaned until the bottom (corm) was completely white to ensure that they were not contaminated by any insect or nematodes. Suckers cleaning were carried out in the field where the planting material was collected in order to avoid contamination of the new farm with nematodes or corms with stem borers. These treated suckers were classed and carefully arranged in the farm for about two days in a shaded place before they were planted in the farm.
