Effect of chemical and hand weeding on groundnut productivity

Background: Weed infestation significantly threatens groundnut productivity, particularly during the later stages of growth. productivity. Objectives: To address this, a field experiment was conducted at two distinct locations under rainfed conditions in Nigeria’s Southern Guinea Savanna to evaluate the effects of pre-emergence and post-emergence herbicides, combined with hand-weeding, on weed suppression, yield, and seed quality in two groundnut varieties. Methods: A split-plot field trial tested two groundnut varieties (SAMNUT 23, 26; main-plot) and eight weed-control regimes (sub-plot). Results: Tridax [...]
