Abstract:Cassava (Manihot esculenta Crantz) is an important crop for food, feed and income security. Cassava productivity is limited by poor weed management. Field trials were conducted in Zambia to determine the Critical Period for Weed Removal (CPWR) on 3 cassava varieties (Chila, Mweru and Nalumino), with contrasting canopy structure, using a split-plot design in randomized blocks. Nine weeding treatments, i.e., control, 21, 42, 63, 84, 105, 126, 147, 168 days after planting (DAP), were applied on two sets of weedin… Show more
