Other claims from this paper (16)
- Intervention effect Rotary hoe cultivation reduced weed seedling density by 39 to 74% in two years.
- Intervention effect Tine weeding was more effective than rotary hoeing in 1992.
- Intervention effect Rotary hoeing reduced corn populations by an average of 6%.
- Intervention effect Tine weeding reduced corn populations by an average of 6%.
- Intervention effect Weed control varied little among inter-row cultivator types, apart from stated exceptions.
- Intervention effect An in-row cultivator controlled weeds better than a rolling cultivator in two years.
- Intervention effect An in-row cultivator controlled weeds better than a shovel cultivator in one year.
- Intervention effect Herbicides better controlled weeds arising from seeds in all three years.
- Intervention effect Cultivation controlled weeds arising from roots, rhizomes and tubers as well as or better than herbicides.
- Intervention effect Herbicides plus cultivation sometimes improved weed control over herbicides alone.
- Intervention effect Herbicides plus cultivation damaged corn in two of the three years.
- Intervention effect Mechanical treatments combining inter-row cultivation with rotary hoeing differed in cost from herbicides by less than 2%.
- Intervention effect Mechanical treatments combining inter-row cultivation with tine weeding differed in cost from herbicides by less than 2%.
- Intervention effect Best mechanical and herbicide treatments produced nearly equal corn yields in all years.
- Observation The best mechanical weed-management regime varied among years.
- Intervention effect Mean net return was moderately higher for herbicides.
