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 […]

The use of diazotrophic bacteria can help to achieve higher yields and reduce negative environmental impacts caused by N fertilizers. The aim of this study was to evaluate the effects of seed treatment with Azospirillum bacteria and the application of different rates of mineral N on maize agronomic performance at two levels of yield management. A field experiment was set up in Lages, SC, Brazil, in the 2011/2012 and 2012/2013 growing seasons. A randomized block experimental design arranged in split-split […]

The use of stabilized N sources, with mechanisms for inhibition of urease enzyme and with ammonium nitrification inhibitors, may help to achieve higher grain yields, contributing to the sustainability of agricultural activity. The aim of this study was to evaluate the effect of different mineral N sources and application rates on maize grain yield and N use efficiency. A field experiment was carried out in Lages, SC, Brazil, in a randomized block design in split-plots. Nitrogen was side-dressed in the […]
