Niger, with a diversified agricultural production system, is dominated by the cultivation of millet for cereals, and cowpea for legumes where they are most often grown in combination. Among the cereal/legume combinations observed, the millet/cowpea combination is by far the most used by producers. This study aimed to evaluate the field experiment in 2021 rainy conditions, the growth, and the yield and yield components of millet/cowpea intercropping. A split-plot design was employed in this experiment, with treatments in main plots, and the varieties in small plots. Treatments included millet sole crop, cowpea sole crop, and intercropping millet/cowpea. Three genotypes of cowpea and a variety of millet, Heini Kirey Précoce (HKP) were used in this study. Growth and yield variables such as leaf area index (LAI), specific leaf area (SLA) and crop growth rate (CGR), biomass and seeds yield, millet 1000 seeds weight, harvest index, and LER were determined. Four cuts were made to determine the growth variables, at the tillering stage, elongation stage, 50% flowering of millet, and dough stage of millet grains. The results showed that total dry matter achieved by intercrop was significantly higher than those achieved by either millet or cowpea sole crop. Grain yield and thousand grain weights of millet were not affected by intercropping while cowpea did not produce any grain. The LAI was higher in intercropping than in sole crops, with higher values at the dough stage of the grains. The growth was maximal for both crops between the second and third cut with optimal growth rates. The LAI was higher in association than in pure culture and with higher values at the dough stage of the grains. Growth was maximum between the bolting and 50% flowering stages with optimal LAI and growth rate values.
