Other claims from this paper (10)
- Association Cowpea variable cultivation cost was substantially influenced by weed control cost.
- Intervention effect One hand-weeding input cost more than one PRE-herbicide input.
- Association More frequent weed control did not guarantee greater economic benefits.
- Intervention effect Three hand weedings increased variable weed-control cost.
- Intervention effect PRE-herbicide combined with hand weeding gave the highest cowpea yield.
- Intervention effect PRE-herbicide combined with hand weeding gave the highest gross profit.
- Intervention effect PRE-herbicide alone gave the highest benefit-cost ratio.
- Association Cowpea row spacing mostly did not affect economic differences among weed-management methods.
- Association Economic benefits generally declined as cowpea row spacing increased.
- Recommendation The authors recommend minimizing hand weeding with PRE-herbicide, especially at narrow cowpea row spacing, to optimize yield and profit.
