Effects of grass and dadap mulches on some soil (an Inceptisol) properties and yield of taro (Colocasia esculenta) in Western Samoa
and
A latin square experiment with five treatments was carried out in Western Samoa to examine the effects of grass (Panicum maximum L.) and dadap (Erythrina spp.) mulches at 30 and 60 t ha-1 on some properties of a Humitropept soil and yield of taro (Colocasia esculenta). Results indicate that grass and dadap mulches, the former more effectively, reduced soil temperature and weed growth over eight weeks. Soil organic matter and CEC were improved by both mulches. Available N and K levels of the soil and the vegetative growth and yield of taro were increased by mulching but dadap was more effective than grass.
