New Holland FR850 & FR9060 - Silage Harvester

A second crop of corn different from the usual: sown in a row and then with a sowing density greater than the usual sowing at 75 cm. In the last few years, there are several who have performed the tests and use it as an alternative to traditional precision sowing: it allows the approach of two rows, which are called bins, to 22 cm, within which the arrangement of the seeds is offset. The distance between each pair of files and then between the bins is 53 cm (there is also the matching 20-55). The numbers were not randomly selected: the result of 53 + 22 is in fact 75, well known to everyone. This involves the complete adaptability of the plant for processing and harvesting with conventional heads at a distance of 70/75 cm between the files (except for the weeding naturally). Of course, not all varieties of corn can be used for this plant with a density of 10 seeds / sqm, higher investment than the traditional 9 or 7.5 seeds / sqm; therefore, new generation hybrid varieties are needed that do not lose their productive potential with the high sowing density, thanks to a greater seal in agronomic and sanitary terms. According to tests carried out in recent years, in several Italian environments typical for maize cultivation, production increments of 8-13 q / ha of grain were found. As regards silkworms, speech is more complex: establishing accurate values ​​of actual growth is not easy and many more tests are under way, which must take into account the multitude of variables involved in the production of chopped corn. The height of the plant, crucial to a large production, is certainly lower than the traditional sowing investment.
