Abstract

The pot experiment which was carried out at the Farm House, School of Agriculture and Industrial Technology, Babcock University, Ilishan-Remo, Ogun State, Nigeria with the aim of evaluating the potentials of Siam and Mimosa weeds as bioherbicides along with a chemical herbicide Force-Uron and their combinations for weed control efficacy, growth and nodulation of Cowpea Vigna unguiculata Ife Brown variety. Six (6) treatments, namely: Control (no herbicides), chemical herbicide (Force-Uron) applied sole at 4liters/ha, Siam weed (bioherbicide) applied sole at 30kg/ha, Mimosa weed (bioherbicide) applied sole at 30kg/ha, 50:50 chemical herbicide/ bioherbicide (Siam weed), 50:50 chemical herbicide/ bioherbicide (Mimosa weed) were replicated four (4) times using a Randomized Complete Block Design (RCBD). Results showed that Siam bioherbicide was superior in terms of weed control, stimulation of higher nodule weight and higher cowpea shoot, tissue N concentration than the mimosa bioherbicide. The applications of the two 50:50 chemical herbicide/bioherbicide combinations showed higher efficacy in weed control in terms of low weed count and dry matter weight, nodulation especially nodule dry weight, than the application of the sole herbicide types- an expression of synergy in respect of combined use of chemical herbicide and bioherbicides; Siam and Mimosa weeds respectively.
