A field experiment was conducted in 2014 rainy season at the Teaching and Research Farm of Adamawa State University, Mubi located in Northern Guinea Savanna of Nigeria. Two varieties of Bambara groundnut (Vigna subterranean (L) Verdcout) (barnbos and idon bazaura) were evaluated using six levels of pendimethalin (0.5, 1.0, 1.5, 2.0, 2.5, 3.0 kg a. i./ha) along with hoe —weeded and unweed as checks. These were laid out in a split-plot design with varieties in the main plots, pendimethalin in the sub -plots and replicated three times. The objective was to ascertain the optimum rates of pendimethalin for weed control in bambara groundnut. Genotype had no significant effect on crop performance except 100-grains weight, whereby bambos produced heavier grains than idon bazaura. Application of pendimethalin at 2.00 kg a. i. /ha and higher rates reduced crop vigour and canopy height at 3 weeks after sowing, All rates of pendimethelin produced comparable grain yield with the hoe weeded treatment. The study revealed that pendimenthalin at the rate of 0.5-1.5 kg a. i./ha could possibly be used as alternative to hoe-weeding for weed control in bambara groundnut.
