Field experiments were conducted in 2010 and 2011 rainy seasons to assess the benefits of intercropping selected grain legumes with Pennisetum glaucum L. at the Teaching and Research Farm of the Department of Crop Production, University of Maiduguri, Maiduguri, Nigeria. The treatments consisted of four pearl millet varieties namely SOSAT-C-88, ZATIP, LACRI-9702-IC and EX-BORNO and four legume types namely groundnut (Samnut–14), soybean (TGX–1830-2E), cowpea (IT89KD-288) and bambaranut (Damboa white). Additive sowing row of the trials were laid out in a Split-Split Plot Design with legumes assigned to the main plots and the pearl millet varieties assigned to the sub-plots in 1:1 alternative row arrangement; with three replicates. The results obtained indicates that the number of pods/plant correlated positively with the length of branches at harvest, and the number of branches at harvest. While legume plant height was positively associated with 100 seed weight as well as with the number of branches at harvest. In addition, weight of pods yield/hectare was positively correlated with length of branches at harvest, number of branches at harvest and number of pods/plant. Linear relationship among agronomic parameters revealed that, grain yield/hectare increased with increase in length of branches, number of branches/plant and number of pods/plant. Higher grain yield and monetary advantages were realized for cowpea + millet and groundnut + millet intercrop than the other associations. The legumes were more competitive when grown in association with millet varieties LACRI-9702-IC and SOSAT-C-88, which produced shorter plants. The SOSAT-C-88 realized greater yield advantage, while ZATIP realized greater monetary advantage among the pearl millet varieties. There was mutual cooperation between cowpea + SOSAT-C-88 intercrop as indicated by the greater yield and monetary advantages. Both Grain yields and cash returns were best realized by pearl millet variety SOSAT-C-88 in association with cowpea and groundnut in the Sudan savannah.
