Summary in the original language of the document

Practical recommendations: The plant physiology gives a good indication on the variety’s ability to compete with weeds. The handbook for Cereal Variety Testing for Organic and Low Input Agriculture recommends using a combination of different components: Crop ground cover (%): measured at early tillering, Growth habit (e.g., inclination of leaf): measured at the start of tillering, Tillering capacity (number of shoots/m2) should be combined with other measurements, Rapid early growth to stem extension (days or 1-9 scale), Plant height (cm): should be combined with other measurements.

Teaser:	Assess weed competitiveness!
What problem does the tool address?:	In many EU countries, weed competitiveness is not part of official variety testing protocols. Organic farmers that forego herbicides and conventional farmers that wish to reduce spraying, face the problem of identifying wheat cultivars that are suitable for their management conditions.
What solution does the tool offer?:	Farmers can set up on-farm trials to test different wheat cultivars. The farmer can use the cultivar which he usually cultivates as a reference variety. Next to the field, 2 to 3 cultivars are sown in strips and compared to the reference. The same management practices are performed uniformly to the trial fields. Visual assessment of a combination of different plant physiological properties can be used for evaluating the cultivar’s weed competitiveness. Ideally, the trial is repeated over several seasons. Networking and discussion groups among farmers to share experiences can help to give a good overview over a broad range of potential cultivars.
