e0“No-tillage on the Anira peat rather than on the Onverwagt clay, with adequate weed control, is therefore preferred at the present time for cowpea production on the coast of Guyana”

Other claims from this paper (7)
- Observation Conventional tillage did not improve physical characteristics of Anira peat.
- Intervention effect Cowpea growth and yield on Anira peat were not significantly affected by tillage.
- Mechanism Poor weed control was proposed as the principal reason for lower average yields without tillage on Anira peat.
- Observation Tillage significantly improved physical properties of clay soil.
- Intervention effect Cowpea yield did not differ significantly between tilled and untilled clay plots.
- Mechanism Poorer soil physical conditions appeared to explain the lower mean yield on untilled clay plots.
- Recommendation Further management research was recommended for clay soils.
