Other claims from this paper (9)
- Intervention effect Conventional tillage gave a 31% soybean yield advantage over no-till.
- Intervention effect June planting gave a 43% soybean yield advantage over May planting.
- Intervention effect Preemergence plus postemergence weed control gave a 51% soybean yield advantage over their counterparts.
- Intervention effect Conventional tillage improved weed control by 18% over its counterpart.
- Intervention effect June planting improved weed control by 12% over its counterpart.
- Intervention effect Herbicides applied preemergence and postemergence improved weed control by 31% over their counterparts.
- Intervention effect Postemergence bentazon gave no difference in soybean yield from two timely cultivations.
- Recommendation Planting soybeans about 1 June may achieve better yields than 1 May planting when mid-season rainfall is deficient.
- Association Lack of yield response of Williams soybeans to narrow-row spacing and early planting was attributed to limited rainfall and incomplete weed control.
