Abstract
Field trials were conducted in the wet seasons of 2014 and 2015 to evaluate the effect of Pre- and
Post-Emergence herbicides for weed control and performance of groundnut to address the
problem of low yield due to weed interference in the crop. Among the ten weed control
treatments evaluated in a Randomized Complete Block Design (RCBD) replicated three times,
the mixtures of metolachlor + prometryn at 2.5 + 1.5 kg a.i/ha, metolachlor + terbutryn at 3.34 +
1.68 kg a.i/ha and ametryn + terbutryn at 3.2 + 2.0 kg a.i/ha gave better growth and pod yield of
the crop. However, application of metolachlor + metobrumuron at 1.5 + 1.0 kg a.i/ha and
ametryn + terbutryn at 2.4 + 1.5 kg a.i/ha gave lower crop vigour, higher crop injury score, high
weed infestation and lower pod yield. It can be concluded that the first three promising herbicide
mixtures above (metolachlor + prometryn at 2.5 +1.5 Kg a.i./ha, metolachlor +terbutryn at 3.34
+1.68Kg a.i./ha and ametryn +terbutryn at 3.2 + 2.0 Kg a.i./ha), can be adopted by farmers
instead of hoe-weeding for weed control in groundnut in Northern Guinea savanna of Nigeria
