Notes from the Additive Method | Notes from the Substitutive Method |
Beggartick reduces dry mass accumulation in soybean, even at low densities | Beggartick reduces slightly soybean dry mass, in any proportion, when plant density in the system is near the maximum |
More than 20 beggartick plants∙m−2 are highly impacting on soybean grain yields | Even in minority, beggartick is highly capable of reducing crop yields |
Beggartick reduces linearly dry mass accumulation in corn as infestation increases | Corn is affected by beggartick in constant ways, independently of density of the weed |
Sourgrass is not capable of impact soybean significantly, when under equivalent densities and under concomitant emergence (plants originated from seeds) | Soybean is highly capable of competing against sourgrass, even when the weed is superior in density; there are, however, losses in dry mass accumulation by the crop |
The reduction in dry mass accumulation of corn was linear to the increase in sourgrass density | Corn potential to compete against sourgrass is constant, with minor losses by competition |
| For all situations, there is mutual prejudice in growth for all species under competition, at different levels (PRT < 100) |
