    The Maize Harvest

The highlight of every season: The harvest

For every farmer, harvesting is labour-intensive but also satisfying. After a long period of growth and development, we finally reap what was sown. There also there are different procedures and aspects to consider for each type of crop.

Maize can be harvested as grain maize and silage maize for animal feeding or as a substrate for biogas plants. Whereas silage maize for animal feeding and biogas maize are harvested in the same way, grain maize harvesting differs fundamentally from them.

KWS has summarised the most important differences concisely for you.

Various uses - different harvesting methods

Stubble processing after the maize harvest

Intensive working of the stubble and soil after the maize harvest is a very good measure for maize borer control and for combating fusariosis in the subsequent crop. Various experiments have shown that the use of mulchers after harvesting maize can substantially reduce both the number of maize borer larvae and the incidence of fusariosis in the subsequent crop. The reduced incidence of fusariosis also significantly minimises the risk of excessive DON contents, for example in a subsequent crop of winter wheat.

For this reason, intensive comminution of the maize stubble is especially important. The graph below illustrates the comminution quality of various mulchers.

As you can see in the graph, there are definite differences in the comminution quality of maize stubble with various mulchers. In this experiment, the flail mulcher with large hammer flails gave the best results.
