Aim: The experiments were conducted to determine effects of time of introducing sesame into maize or vice versa on the performances of the intercrops. Study Design: Randomized complete block design replicated four times. Place and Duration of Study: Teaching and Research Farm, Ladoke Akintola University of Technology, Ogbomoso, Oyo State, Nigeria in 2008 and 2009 cropping seasons. Methodology: The treatments were (i) Sole Sesame (0 week) (ii) Sole maize (0 week) (iii) Sole Sesame ‐ established 2 weeks later (iv) sole Maize ‐ established 2 weeks later (v) Maize/Sesame (0 week) (vi) Maize/Sesame (sesame introduced into maize after 2 weeks) and (vii) Sesame/Maize (maize introduced into sesame after 2 weeks). The test crops were sesame (Sesamum indicum) variety E8 and Maize (Zea mays) variety ACR-9931-DMR-SR-Y. Five sesame plants were randomly selected per plot and tagged for collection of data on plant height and podding nodes. At maturity,
