Effect of the competition of Johnson grass on maize in the early growth stages


, : Effect of the competition of Johnson grass on maize in the early growth stages. Revista de la Facultad de Agronomia, Universidad Nacional de La Plata 55(1/2): 85-94

In pot trials, maize Record 120 was grown alone or in competition with Sorghum halepense at densities equivalent to 600 000, 1 200 000 and 1 700 000 plants/ha. Conditions were arranged so that competition was for light, nutrients or light + nutrients for up to 35 days.
