PRODUTIVIDADE ECONÔMICAE COMPONENTES DA PRODUÇÃO DE ESPIGAS VERDES DE MILHO EM FUNÇÃO DAADUBAÇÃO NITROGENADA
The effect of nitrogen (N) doses on yield of the green maize ears and its production components was evaluated during two years. Five N doses (0, 60, 120, 180 and 240 kg ha-1) applied in topdressing were tested in a randomized block design with four replications. The efficiency of treatments was eval...

| description | The effect of nitrogen (N) doses on yield of the green maize ears and its production components was evaluated during two years. Five N doses (0, 60, 120, 180 and 240 kg ha-1) applied in topdressing were tested in a randomized block design with four replications. The efficiency of treatments was evaluated by the production and the number of commercial green ears per hectare, weight of husked and unhusked ears, length and diameter of unhusked ears and husked ear/husk ratio. Increases in husked commercial ear yield by N application were found, with maximum production of 13.52 t ha-1 estimated by 157 kg ha-1 N application (first year) and of 14,86 t ha-1 with 177 kg ha-1 N dose (second year). The increases in the production of green ears were not due to increases in the number of ears per area and by length of these. Differently of husked ear/husk ratio, the average weights of the husked and unhusked ears and diameter of unhusked ears were affected by N application. It was proposed a table of recommended N doses based on pre-establishedprices of N and commercial ears. |
