Growth of irrigated plants has continued to be impressive at Aylesbury farm with some now over 1.5 m tall. Karetu farm received its first significant rainfall since February 6 on March 19 with 26 – 30 mm of rain over two days. This resulted in what were apparently dead MxG plants sprouting new shoots, indicating the robustness of this plant. Recent rainfall in early April brought about further new vigorous growth as illustrated by fig.3. In comparison the Poplar trees next to the MxG plantings, Fig.2, shed their leaves long ago and may not have survived.
The past month has been characterised mainly by the severity of the drought that has affected most parts of the North Island and some of the South Island. We have Miscanthus growing in enough different places to begin to get a good picture of how well it handles drought. I find the results somewhat surprising
The plants in the adjacent corner which receive a regular water supply from the centre pivot, as shown in fig. 2, are thriving and many of these are now a metre tall. It will be interesting to see how all MxG plants in this paddock develop and whether the drought-affected plants ever achieve a worthwhile dry matter yield over the next two seasons.
This is the inaugural issue of what will be a monthly update of activity in the world of Miscanthus New Zealand Limited. Our first two and a half years have been very busy as we move from having 34 plants that we imported in tissue culture, to supplying several hundred thousand plants to landowners who
This month has seen a continuation of last month’s dry and hot weather causing very dry conditions. This is being reflected in the occurrence of two severe bush fires near two of the farms where Miscanthus giganteus (MxG) has been planted. Fortunately at Aylesbury farm where all MxG plantings are irrigated this hot weather has produced ideal growing conditions.
There are now three dairy farms planted with Miscanthus giganteus (MxG) with a total of 10 paddocks being used to firstly investigate the growth potential of the plant itself and also to monitor its effectiveness in providing ecosystem services to dairy farms. There may also be potential to plant further paddocks next season.
Planting of Miscanthus giganteus (MxG) in the first four paddocks took place on the 13th and 14th of November at Aylesbury Road farm. The existing grass was first sprayed with Roundup and then left for two weeks before being cultivated the day before planting.Thank you Mark for organising this and to those who carried out the work. Also thanks to all my farms for giving me the chance to test the potential of what hopefully will prove to be a very interesting plant.
My research proposal has been approved subject to two adjustments. One of these was to narrow the scope of the research, as it was felt that too broad an area was being considered and the other was that I needed more paddocks planted with Miscanthus to provide a robust trial that would give statistically valid data. To address the points raised we have decided initially to concentrate on the eco-system service benefits generated from creating Miscanthus shelterbelts. I am in discussion with Pete Morrison and David Irvine about planting Miscanthus on their farms and I should hopefully have ten paddocks from which I can collect data.
