| Abstract: The objective of this work was to evaluate the effect of application of the growth regulator Trinexapac-ethyl on maize response to the increase in plant density at two sowing dates. A field experiment was carried out in the municipality of Lages, state of Santa Catarina, Brazil, during the 2014/2015 and 2015/2016 growing seasons. Two sowing dates (10/15 - preferential, and 12/5 - late), four plant densities (5, 7, 9, and 11 plants m-2), with and without Trinexapac-ethyl application, were tested. The growth regulator was sprayed at a rate of 150 g a.i. ha-1, when hybrid P30F53YH was at the V5 and V10 growth stages. The spraying of Trinexapac-ethyl decreased the stem length above the ear insertion node at both growing seasons. Grain yield ranged... |

| A utilização de bactérias diazotróficas pode auxiliar a alcançar maiores produtividades e reduzir os impactos ambientais decorrentes da utilização de fertilizantes nitrogenados. Este trabalho foi conduzido com o objetivo de avaliar o efeito do tratamento de sementes com bactérias do gêneroAzospirillum e da aplicação de doses de N mineral sobre o desempenho agronômico do milho em diferentes níveis de manejo. O experimento foi conduzido no campo, na cidade de Lages, SC, durante os anos agrícolas de 2011/2012 e 2012/2013. Utilizou-se o delineamento experimental de blocos ao acaso dispostos em parcelas subsubdivididas. Na parcela principal, foram testados dois níveis de manejo, o médio, expectativa de produtividade de 8.000 kg ha-1; e o alto, expectativa de... |

| ABSTRACT Currently, most nitrogen fertilizer is side-dressed when corn is in the four (V4) to eight (V8) expanded leaf stage. However, recent studies have shown that modern hybrids take up high amounts of nitrogen during grain filling. This indicates that a late nitrogen fertilization, at the time of crop flowering, may be important to optimize corn agronomic performance. This study aimed to evaluate the effect of the timing and splitting of nitrogen side-dress application on the agronomic performance of early corn hybrids in order to achieve high grain yield. The experiment was set in Lages, Santa Catarina, in the South of Brazil, during the 2014/2015 and 2015/2016 growing seasons. A randomized block design arranged in split plots was used. Two hybrids... |
