Abstract
Taller plants of sorghum and maize in Kenya produced greater yields of grain at harvest than shorter ones, but under intercropping conditions maize always out-yielded sorghum when planted at the same time, whether the sorghum was planted in the same hill as maize, in alternate hills or in alternate rows. There were generally more stem-borers in sorghum than in maize, with Chilo partellus (Swinh.) predominating and Eldana saccharina Wlk., Busseola fusca (Fuller) and Sesamia calamistis Hmps. also present. Intercropping increased the level of stem-borers in maize, while infestation was low in pure stands of maize; borer infestation remained about the same in sorghum. Borers had a considerable effect on the yield of maize at Mbita Point on the shores of Lake Victoria; losses were significant when 38-52% of internodes were bored
