Effect of cassava-legume intercropping systems on productivity and cassava insect pests population dynamics across three major agro-climatic zones of Sierra Leone

Field trials were conducted in 2015/2016 and 2016/2017 cropping seasons three agro-climatic zones of the country to evaluate productivity insect pests population dynamics cassava as a response spatial arrangement, plant architecture systems. The treatments consisted seven associations, two architectures arrangements. study reveals that yield parameters higher cassava-soybean system at all locations. number marketable roots forage on average when erect variety was intercropped with legumes using 1 m x 1m arrangement. On other hand, root canopy width 2 0.5 arrangement branched used respectively. In general, Segbwema expect for Makeni. With respect pests, percentage incidences severity scores recorded sole cassava. addition, only observed 6 MAP 9MAP compared Thus, order improve low pest infestation, should be soybean m.
