dc.description.abstract | In the piedmont of the Eastern Plains of Colombia, was established the association of corn with the grasses B. decumbens, Mulato and Toledo, to renovate degraded pasture. The effect of the N was evaluated with 100 and 200 kg ha-1 applied to the corn to the 15 and 35 days after the sowing (das). The available N in the soil in nitrate form remained N in 42 and 43 kg ha-1 to the 15 and 35 das respectively, coinciding with the fertilization of N applied to the corn, but to the 60 days it reducing to 11.9 kg N ha-1. The available N in ammonium form was of 82, 84 and 72 kg ha-1 to the 15, 35 and 60 das, respectively. To the beginning of the flowering, the N leaf in the corn associated with B. decumbens and with the grass, Toledo was respectively of 2.9 and 2.83%, while in the association with grass Mulato was of 2.66%. The N leaf in the grasses Mulato and Toledo was respectively of 3.31 and 3.20%. In the phase of filled grain of corn, the N leaf in the corn didn’t present significant differences when being associated with the three grasses, being obtained an average of 2.59%. The treatments with 100 and 200 kg N ha-1 applied to the corn didn’t affect the content of N in the leaves of corn and grass, so much in the moment of the flowering like in the one filled of the grain. |
