Abstract

Two field trials were conducted at the research farm of the National Root Crops Research Institute (NRCRI) Umudike, Igbariam sub-station (060151N, 060521E) in 2013/2014 and 2014/2015 cropping seasons to determine the growth and yield of  cassava as influenced by maize and cowpea population densities. Cassava at a density of 10,000 plants per hectare was  intercropped with maize at 13,333, 20,000 and 40,000 plants/ha, and cowpea at 16,666, 22,222, 33,333 plants/ha,   respectively. Cassava was planted in monoculture and intercropped with maize and cowpea. The experiment was arranged in a Randomized Complete Block Design (RCBD) with three replications. The results revealed that increasing maize population beyond 13,333 plants/ha significantly reduced growth and yield parameters of cassava. Also, growth and yield attributes of cassava significantly increased as cowpea density increased from 16,666 to 33,333 plants/ha. However for optimum growth and yield of cassava in cassava/maize and cassava/cowpea mixtures respectively, cassava at 10,000 plants/ha + maize at 13,333 plants/ha or cassava at 10,000 plants/ha + cowpea at 33,333 plants/ha are recommended in the study area.
