After the 2nd week of the experiment, perennial rye-grass had the highest height of its above-ground part compared to plants of other species.
Analysis of the weekly plant increment shows that the biggest increment of the above-ground part of plants was recorded on the 3rd week of growth, when perennial rye-grass increased by 1.9 cm in the substrate contaminated with 5 g/kg of NaCl, and 4.1 cm in the substrate containing the mixture of NaCl and Safecote.
Italian rye-grass hay, similar to the feeding material, was used in the test forage sample.

The growing period for the rye-grass was 6 months and for the Melaleuca armillaris 32 months.
At the end of the growing period (32 months for Melaleuca armillaris and 6 months for rye-grass), the nutrient solution in the tubs containing rye-grass and Melaleuca armillaris were emptied and the assemblies dissected in a vertical plane using a bandsaw for PVC pipes and a diamond saw for FRC pipes.

New rye-grass research by scientist Rocio Alarcon-Reverte - co-funded by HGCA and Syngenta and supervised by Rothamsted Research and the University of Reading - has found a basic misunderstanding of its germination process.
According to Dr Stephen Moss of Rothamsted Research, many farmers delay spraying rye-grass in winter cereals because of a belief that it mainly germinates in spring.
Other species struggled with the husks of barley and rye-grass, which are difficult to strip from the kernel.
FARMERS are being advised to take advantage of the arrival of warmer conditions to tackle growing rye-grass populations in cereals.
