Weed supression by smother crops and selective herbicides

HIGHLIGHTS

• who: Roberta Accurso from the on hairy beggarticksWhen the smother crop shoot biomass was left on the soil surface, there was no difference in the effect among the legumes. Figure, a shows the average value for the weed biomass yield as a function of the average of the three legume species. Different effects were observed when smother crops were incorporated into the soil. Results are shown by species in Figures, b to, d. Guineagrass was highly suppressed by the three green manure crops. However, the greatest effect was caused by pigeon pea, especially with the higher quantities . . .
