Abstract
The effect of tillage on the dynamics of buried weed-seed population was studied during 1989-90 in the crop fields at Barapani. The conventional tillage increased the total buried weed-seed population by 3-4 limes compared with no-tillage, but reduced the proportion of viable-dormant seeds significantly (P < 0.01) in the former. The weed seeds were concentrated more in the surface layer of the soil than in the deeper layers in no-tillage, but reverse was the position in the conventional tillage. The proportion of viable dormant seeds was significantly (P < 0.0 I") higher in the deeper soil layers than in the surface layer.
