Other claims from this paper (9)
- Intervention effect Adding extra N to no-tillage corn increased yields of both corn and bahiagrass.
- Intervention effect No-tillage corn in rye treated with paraquat plus residual herbicides generally yielded about the same as conventionally planted corn.
- Observation Pensacola bahiagrass recovered quickly after paraquat plus residual herbicide and competed with corn for water and nutrients.
- Intervention effect Pensacola bahiagrass treated with glyphosate in combination with other herbicide was almost all killed and offered little competition to corn.
- Observation Fall forage yield of Pensacola bahiagrass was only 37% of its yield after paraquat-residual herbicide application.
- Observation The effectiveness of atrazine, cyanazine, alachor, linuron and their combinations in controlling broadleaf weeds varied seasonally.
- Intervention effect Atrazine, cyanazine, alachor, linuron and their combinations had no significant effect on corn yields.
- Intervention effect Weed growth at corn harvest was considerably less on no-tillage plots.
- Intervention effect Perennial weeds began to appear after three years of continuous no-tillage corn, while few were observed in conventionally planted corn.
