effect of corm size and plant population density on corm yield of taro (colocasia esculenta l.)

objective: taro (colocasia esculenta l. schott) is a perennial root crop that belongs to araceace family.  it is widely cultivated as a staple food in africa, asia and pacific islands. despite its importance, there is limited information on many aspects of the crop. in order to obtain data that can support improved and sustainable taro production, a field trial was conducted to study the effects of corm size and plant population density on the growth and corm yield of taro (variety boloso-1) was investigated during 2007 cropping season. methods: the experiment consisted of five-corm size (50, 51-100, 101-150, 151-200 and 201-250 g) and five levels of planting densities (15037, 29629, 45454, 60606 and 74074 plants/ha) arranged in a factorial randomized complete block design with three replications. results: the results indicated that corm size had a highly significant (p
