Effect of Intercropping on the Development of Cassava Bacterial Blight

Abstract

The effect of intercropping cassava with maize or cowpea in two arrangements i.e. both crops in the same row or in alternate rows, on cassava bacterial blight has been compared to cassava monoculture in the forest-savannah transition zone of Nigeria using a randomized complete block design. Result of study revealed that in cassava monoculture, more severe disease symptoms developed than in intercropping patterns. Further, following order of disease severity: cassava monoculture > cassavacowpea in alternate rows > cassava-cowpea in the same row > cassava
