Plant architecture and N fertilizer may limit the performance of intercropped maize (Zea mays L.) and cowpea [Vigna unguiculata (L.) Walpers] cultivars. This paper describes an experiment in which cultivars of maize and cowpea were intercropped and fertilized with varying rates of N. The cowpea c...

Twelve samples of Striga hermonthica seed were collected from four host crops [millet (4), sorghum (4), a sorghum/millet intercrop (3) and maize (1)] from all the main areas of S. hermonthica infestation in Nigeria and were tested on eight genotypes of three test crops [maize (4), sorghum (2) and...

Farmer-managed trials in developing countries often show great variability in yield and treatment effects. The use of statistical techniques is demonstrated to explain this variability in a maize + cassava intercropping trial in southwestern Nigeria. Concomitant variables, measured in the trial f...
