Things were very hectic through January and into February. I do not think I really realised at the time we purchased the Taharoa C Block Incorporation Miscanthus assets, just how much work this would involve. Whereas we had previously been focusing on the production of plantlets with the aim of getting into rhizomes eventually, plus
Well with all the rush of activity immediately prior to Christmas, the monthly chat was noticeable by its absence. This was accentuated by my wanting to delay posting another message until some interesting developments had come to fruition one way or the other. The other significant player in the Miscanthus business in New Zealand –
As anticipated in Newsletter 10, damage to the Centre Pivot at Aylesbury Farm caused problems with some early-season Miscanthus (Mxg) growth but fortunately severe damage has occurred only with the shelterbelt in paddock 22. Pivot repair was finally completed on December 8 but due to part of the pivot falling onto the Mxg shelter in paddock 22 many of the plants were driven over during repair.
The growing season for Miscanthus is well underway and even in areas that have not been harvested, the Miscanthus is shooting up extremely quickly. Three weeks ago at a site in the South Waikato area, the Miscanthus was already knee height and the change from one week to the next has been quite exciting to
The first signs of re-growth started to appear at the beginning of September. Stems that senesced over the winter remained soft and did not stiffen to produce harder stems, as had been expected. This may be a feature of first season’s growth or may have been a consequence of the relatively mild winter resulting in a slower rate of nutrient transfer. M. x gianteus (Mxg) is not harvested in its first season but when considering future harvest date research (Lewandowski and Heinz 2003) shows energy yield is reduced the later the harvest date, due to nutrient content decreasing as nutrients are translocated to the rhizome.
An American colleague of mine who is involved in Miscanthus research and teaching said to me some time back that development of a Miscanthus industry is a business that takes quite some time to get going. For somebody as impatient as I am, it was frustrating to hear that, but she is quite right. So
You would really think that because it is the time of year when things are not growing, this would be the quiet time of year in the Miscanthus business. But it is in fact the time of year when we are trying to get people to firm up on their decisions about how many plants
June is the month that I always associate with cold damp weather which is characteristic of the National Fieldays. This year, my annual pilgrimage to the Fieldays found that although it was quite cold it was not damp and in terms of weather was quite a pleasant day. It was also different in that I
Miscanthus plants are now starting to senesce and pass nutrients to their rhizome (Fig. 1). First year-yields are not worth harvesting and so the remaining woody stems will stay in place until new growth commences next spring. Miscanthus planted in the irrigated paddocks of Aylesbury Farm achieved a maximum height of 1.5 m which is impressive considering the late planting and initial lack of irrigation. This growth was achieved from initially water-stressed plants in just four months. Expected height from growth over seven months was 1 m.
Interest in Miscanthus is growing rapidly and Miscanthus New Zealand (MNZ) has had a number of enquiries from people wanting to order small quantities to establish tiny trial areas of Miscanthus on their properties. These will all be interesting but MNZ is conscious of the fact that they give little information on the possibilities for
