Can growers reduce their input costs whilst maintaining yields?
Following four years of research, Diana Mathers of the Foundation for Arable Research (FAR) is confident they can. If
growers simply adopt a single pass planting system for maize they will reduce their input costs whilst also maintaining
yields she says.
"Over time it will also improve soil quality. Trials at the FAR Waikato Arable Research Site, and on farm trials across
a number of regions have shown that using a single pass planting system has not compromised yields, and although a slow
process, the soil attributes have also improved." So why are maize growers not adopting this technique? "Getting farmers
to give it a go is difficult - they are often concerned that it is too risky for their farm."
Funded by MAF SFF and co-funded by FAR, FAR will be delivering a number of discussion groups in Taranaki, Waikato and
Manawatu to discuss reduced tillage options for maize with farmers and contractors. A number of on-farm demonstrations
will occur which aim to compare the usual planting practice with a single pass planting system to encourage discussion
and learning.
"We've drawn together a group of experts and a list of the things that must be considered to get a good result to
support those that are giving it a go. These include; what needs to be done to the planter, what are the best soil
conditions and what should growers be looking out for when the crop is young."
The aim is to determine how reduced tillage practices for maize will work in these regions with the hope that more
farmers might give it a go. Based on the success at the demonstration sites FAR hopes the adoption rate will increase,
thus reducing establishment costs for those farmers in the long term.
