Optimise chlorophyll production to boost cereal returns



Written by Charlotte Cunningham

A crop enhancer that improves chlorophyll production and maximises green leaf area is producing some impressive yield increases in cereal crops, according to Agrovista. Charlotte Cunningham reports. Klorofill is a liquid formulation of pentanoate, an organic compound that contains a keto acid, a vital precursor in chlorophyll manufacture within plants. “Chlorophyll is essential for photosynthesis, so maintaining efficient production is key for healthy yields and profits,” says Agrovista technical manager John Murrie. All crops stand to benefit, he adds. “Klorofill can help high potential crops live up to their promise by optimising yield, quality and return on investment, especially during rapid spring growth, when chlorophyll production can lag demand. “Plants can also be subject to stress during these times, which causes them to reduce chlorophyll production, compounding the problem. “Pentanoate can reverse the suppression of the chlorophyll pathway, significantly increasing the net photosynthetic rate and gas exchange capacity in stress conditions. “Klorofill seems to build a bigger flag leaf and convert this into yield in many cases. We’ve seen 0.4-0.5t/ha increases in wheat and barley crops on farm.” Derived from plant material, Klorofill is supplied in a fully soluble and tank-mixable liquid formulation applied at 1 litre/ha. It can be…

Maintaining grass quality during mid-season grazing is important. Farmers can maintain quality by entering ideal grazing covers of 1,300 – 1,500kg DM/ha, and grazing down to a residual of 4cm every rotation.

If you are now in a situation where cows are not cleaning out paddocks as well as they should be, leading to the development of steamy grass within the sward, here are some options.

Common options for rejuvenating swards include:

  1. Take a silage cut, probably into bales, remove the material and start again with the aftermath...
