FIORENTIN, Ciro Franco; LEMOS, Leandro Borges; FORNASIERI FILHO, Domingos y JARDIM, Celso Antonio. Intercropping with Brachiaria ruziziensis influence and residual nitrogen in corn crop. Rev. de Ciências Agrárias [online]. 2012, vol.35, n.1, pp.184-192. ISSN 0871-018X.
The no tillage feasibility and implementation in the Brasilian Cerrado region has been limited by the difficulty of obtaining and maintaining adequate mulching on the soil. In this context, the objective was to evaluate the influence of residual nitrogen, applied to common beans, in the leaves number active photosynthetically, the agronomic characteristics and crude protein in corn grains, intercropped or not. We can be concluded there was no residual effect of nitrogen rates application, applied previously in common bean, on the vegetative and reproductive development in corn and corn intercropped with Brachiaria ruziziensis, there was increase in the leaf senescence and reduced crude protein in grains, final population density, spikes number per area, total leaf nitrogen, rachis diameter, kernels number per row and 100 grains weight, without to affect yield.
