Abstract: The objective of this study was to intensify soybean and maize production in smallholder production systems, where land is a limiting resource. Performance during growth and final yield in intercrop was evaluated for cultivars with different growth habits. Field experiments were undertaken at two sites, in two seasons (2002/03 and 2003/04) to evaluate the response of two soybeans (Storm-a determinate and Solitaire-an indeterminate cultivar) to intercropping with three maize cultivars (a semi-erectophile SC513, a planophile PAN413 and AC31; a dwarf cultivar). Treatments were laid in a Randomised Complete Block Design (RCBD) with three replications. Intercropping significantly increased Leaf Area Index (LAI), resulted in greater yields and income per unit land area than sole crops. In 2002/03, maize and soya bean cultivars did not significantly affect Land Equivalent Ratio (LER). However, the maize cultivar by soya bean cultivar interaction significantly (p<0.01) affected LER. Maize cultivar SC513 resulted in the highest LER with Storm but the lowest with Solitaire. It was concluded that SC513, a semi-erectophile intercropped with a determinate soya bean Storm cultivar might optimise yields without significant maize yield reduction.
