Oilseed rape Bio-stimulant range boosts rape establishment
rials suggest oilseed rape crops benefi t from improved root growth and greening follow- ing applications of natural amino-ac- id complex bio-stimulants.
T Independent agronomist Helen
Baxter – who has used the bio-stimu- lant AminoA Flo on conventional oil- seed rape – says it improved root de- velopment, stem thickness and rapid early green leaf growth during estab- lishment. Ms Baxter says she applied AminoA Flo as part of her early spring manage- ment programme after a severe late winter frost damaged rape crops. “We have seen very fast recovery and excel- lent spring growth,” she said. Independent trials data supports the benefi ts of using bio-stimulants, says UK manufacturer AminoA. Rep- licated and on-going trials of the Class A fertiliser have returned further pos- itive results, it adds.
Andy Cheetham of Ceres Agri Ser- vices has several clients growing or- ganic oilseed rape this season. He plans to make amino acids a major part of in-
puts for the organic crops, and is using OF&G approved AminoA Gro. Mr Cheetham made two split appli-
cations of AminoA Gro totalling 2.5l/ha to a fi eld which was hammered with pigeons, stripping the leaves.”The crop recovered within a couple of weeks, with lots of new root growth,” he says. AminoA managing director Rich- ard Phillips says it is important to ap- ply AminoA Flo with a fungicide mix,
Trial sites included the oilseed rape plots at Cereals
particularly at petal fall. “We recommend keeping levels of Flo up to 2l/ha to extend the green leaf area for as long as possible – and get a good pod fi ll.” Yield improvements have been re-
corded in replicated trials. Eurofi ns tri- al results from 2019 saw winter rape treated at the three-leaf stage return a yield increase of 0.38t/ha from a sin- gle autumn treatment.
In these trying times, sometimes it better to look in the shed and see what we can improve, rather than looking at buying new machinery for single uses.
Take Sumo’s Single Disc Openers (SDO) for example: it’s a bolt-on seed coulter unit which, when coupled with a seed distribution unit, such as a Stocks Seeder, enables a regular cultivator to become a true one-pass crop establishment tool.
This set up will till and prepare the soil for seeding, place the seed and firm the seed in place ensuring good soil to seed contact – all in one pass. The unit suits those users who are seeking a more precise
and consistent seed placement than that achieved by simply broadcasting the seed ahead or indeed behind the packer roller.
The SDO is an ideal tool for planting oilseed rape behind a cultivator containing Subsoiler legs. It is a robust design with simple adjustments for seed depth and firming pressure and has been the tool the choice for many OSR growers, one of who has achieved a 15.2/ha yield in East Yorkshire.
Sumo’s SDOs can be fitted to any cultivator but are designed specifically to go behind Sumo’s deep and shallow cultivation ranges.
