The idea of combining a deeper seedbed restructuring pass with precision seeding of oilseeds is being tested in a series of trials that Great Plains is completing with leading industry partners.
These are the latest trials that the company has been involved with over the past 25 years which aim to provide farmers with reliable information on which to base their machinery and cultivation decisions.
As part of this year’s programme, three sites have been established – two with Agrovista and one with Agrii – where crops have been established using a Great Plains Yield-Pro planter working directly behind a Simba ST Bar fitted with LD legs:
“The ST Bar worked to depths between six and eight inches (150mm – 200mm) according to the conditions on each site, which ensures the seed was planted into soil below which the root zone had been effectively restructured, which we believe is the best way to enable the plant to establish a healthy root system”, says David Holmes, UK Sales Director.
The Yield-Pro planter achieves accurate seed singulation, whether working as a conventional planter sowing a single row of seed, or using Great Plains’ patented Twin-Row concept, which sows two parallel rows of seed 15cms apart either side of a centre line and ensures each seed has a dedicated rooting zone and eliminates inter-plant competition and enables it to achieve its full growth potential
A range of different seed rates are being trialled, says Agrovista’s Niall Atkinson:
“We have tried three different seed rates using the planter in Twin-Row mode, the planting 7.5 seeds/metre; 11seeds/m and 15 seeds/m either side of the centre to test which setting achieves the best yield.
“On some of the plots we have also applied seedbed fertiliser by mounting an applicator on the ST bar and placing the fertiliser directly behind the LD legs to see what added benefits that might achieve”.
Farmers will be able to assess the performance of the crops over the year as we are planning to hold a series of open days at the sites. Watch this website for more information.
