Other claims from this paper (6)
- Association Bulk density was negatively correlated with dry matter of crop roots and grain yield.
- Intervention effect Tillage to 28 cm significantly reduced weed population and dry matter compared with tillage at 7 and 14 cm.
- Association There were significant relations between weed dry matter and grain yield.
- Intervention effect Crop roots under tractor tillage were significantly greater than with 7 cm tillage.
- Intervention effect Grain yield was maximum under 28 cm tillage, followed by 21, 14 and 7 cm tillage in that order.
- Association Higher grain yields were associated with more fertile tillers per metre of row and higher yields per tiller.
