Investigations on the effect of ploughing on cassava yield on a sendentary granite-derived soil in the forest area showed significant yield increases when the soil was ploughed compared with the traditional hoe and cutlass cultivation. Deep ploughing beyond 30 em had no advantage over the medium ploughing of 23 em. Nitrogen application significantly increased tuber yield but potassium effect was not significant. At the level of application in this experiment, phosphorus reduced both tuber number and tuber yield.
