Influence of plant prunings on soil properties and yield of yam minisett

Abstract

The importance of the application of agroforestry prunings on improvement of the soil organic matter cannot be overemphasized. The study focused on the influence of plant prunings on soil properties and yield of yam minisett. There is no doubt that effective production of seed yam through minisett technique requires adequate plant nutrient to be available in the soil. The study revealed that application of agroforestry prunings improved soil exchangeable K. The study showed that the plant prunings of Gliricidia sepium seem to be the best of the prunings used in this study in terms of total yield (t/ha), nitrogen, phosphorous and potassium addition to the soil. The resulting effect of this is improvement in the yield of yam minisett.
