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)
