maize in maize-common bean intercropping.

4.2.3. Effect on Yield and Yield Components of maize
Number of ears per plant
Number of ears per plant showed significant (P<0.05) difference due to cropping systems, and
cowpea density but non-significantly affected by cowpea variety and interaction (variety and
density) effect (Appendix Table 3). Significantly higher number of ears per plant (1.733) was
recorded from sole maize than the intercropped maize (1.474) (Table 9). The reduction in number
