3 1. Introduction This report contains the results of four variety testing trials in Poa pratensis, Festuca rubra, Dactylis glomerata and Lolium perenne. The location of the trials was near Ringsted, Denmark. Trial number by Species Agronova Poa pratensis (Engrapgræs) Festuca rubra (Rødsvingel) Lolium perenne (Rajgræs) Dactylis glomerata (Hundegræs) The trials have been carried out by the GEP-unit, Agronova in 2006 for Barenbrug, Holland. 22 November 2006 Morten Lind Agronova LC Field Trials AGRONOVA LC Field Trials 3

5 2.4 Results Two weeks before estimated harvest it was decided that lodging in all plots was too small why swarfing was needed and preformed 10 st of July. The trial was harvested at 17 th of July under fine conditions. In the following table results from harvest and seed analysis is given.

16 6. Trial comments Weather conditions for production of grass for seed in Denmark, Generally autumn was warm and sunny with less than normal precipitation and grasses continued growing longer than normal. Compared to normal, winter was rather cold with average temperatures around 0 ºC. Spring was generally cold and growth started late. April and start of May was dry but the rain came at the right moment. June and July gave fine conditions for flowering and harvest. All together, conditions were favourable for grass for seed production. Poa pratensis (Engrapgræs) Differences between varieties in yield were from (average) kg/ha, with Bariris as lowest yielding and Baron as highest yielding. Baron and Barimpala yielded statistical significant more compared to Bariris. Festuca rubra (Rødsvingel) Differences between varieties in yield were from (average) kg/ha, with Barthema as lowest yielding and Barustic as highest yielding. Differences in yield were statistical significant between all 3 varieties tested. Lolium perenne (Rajgræs) Differences between varieties in yield were from (average) kg/ha, with Bareuro as lowest yielding and as highest yielding. Variety yielded significantly more and Bareuro significantly less than all other varieties. Bartwingo yielded significantly more than Bardoria. Between Bardorado, Bardoria and Bartwingo there was no statistical significant difference in yield. Dactylis glomerata (Hundegræs) Differences between varieties in yield were from (average) kg/ha, with Baridana as lowest yielding and Baraula as highest yielding. Between varieties Baraula yielded significantly more than the two other varieties tested. There were no significant differences between Intensive and Baridana in yield. AGRONOVA LC Field Trials 16
