Growth control improves the yield of grass seed crop – fresh harvest

The use of growth regulators in the cultivation of perennial ryegrass and fescue fescue is the insurance premium for higher seed yields. The condition is that the treatment is carried out on a well-grown crop.

This is the result of a study conducted by the Grass Seed and Ground Working Group from 2018 to 2020 on the plots adjacent to the Rustov Experimental Farm in the College Plot in Zealand. The purpose of the research on the three types of perennial ryegrass and reed fescue is to determine what the crop role is, crop composition and growth control for the final yield.

For example, in contrast to New Zealand and Denmark, grass seed growers in the Netherlands often fear that treatment with a growth regulator will result in leaf burning and yield loss. However, in countries with growth regulation standards, farmers use that approach for higher yields.

The alloy is delayed

In a three-year study of perennial ryegrass, untreated material yielded the lowest yields. Growth regulation yields a lighter crop, but it is not at the expense of seed yield. The composition of the crop also decreases after one treatment.

Researchers conclude that growth control is the insurance premium for higher grass seed yields and thus higher yields in cultivation. The condition is that the application is carried out on a growing crop. During the three dry years of the study, the negative effect of growth regulation on the established yield was not a pattern.

The best crop position for applying growth regulation is between first and second node construction. Grass seed manufacturers have resources like Trimax and Modus available for use.

Correlation for nitrogen addition

In cane fescue, nitrogen content related to growth regulation is also explored. This shows that shared high nitrogen management yields higher yields. Using the modus once or twice will increase the chances of feeling more productive.

The Grass Seed and Grass Cote Working Group operates under the auspices of Plantum and PO Ackerbo and aims to support the cultivation of grass seeds in the Netherlands. For this the grass seed farmers pay a contribution of one hectare.
