Timothy GRINDSTAD

An early, high yielding timothy with good regrowth capacities

• Early variety with very good regrowth capability
• High total yields of green mass
• High yields in second and third cut
• Good winterhardiness
• Excellent persistence
• Well adapted to mixtures with grasses and clovers

• A Norwegian breed, originating from the indigenous race of southern Norway
• Slightly earlier than Tammisto II timothy, heading time is earlier
• Days to heading (from May 1) – 44.4 (in Norway)
• Early, excellent germination
• High yields of green mass
• Great yields also in the II, III years of cultivation
• Good winter hardiness
• Persistent
• Annual average dry matter yield in official trials in Norway (average 9.53 t/ha):
  • in the first year – 11.71 t/ha
  • in the second year – 8.6 t/ha
  • in the third year – 7.27 t/ha
  • Annual average yield of dry matter in various climate zones – 6.74-9.24 t/ha
  • Seed yield potential (in Norway) – 710 (even up to 980) kg/ha
  • Average seed yield (in Sweden) – 405 kg/ha
  • High yields of I cut, but lower than that of the late variety Tammisto II
  • Feed value (D-index) of both cuts, I and II, is lower than that of Tammisto II
  • High yield of II cut and fast regrowth indicate that this is a more southern type variety
  • Injuries in winter – 5.5 %
  • DM yield of first cut – 5.258 t/ha
  • Dry mass in the 1st cut – 23.1 %
  • Dry matter yield in aftermath – 5,866 t/ha
  • Aftermath share from total DM harvest – 53 %
  • Total DM yield – 11,124 t/ha
  • D-value of I cut – 67.7 %
  • Protein content in I cut – 112 g/kg
  • D-value of II cut – 66.6 %
  • Protein content in II cut – 91 g/kg
  • Digestible yield (calculated from total yield and D-value) – very high (higher than that of Tammisto II) – 1st harvest – 3.510 t/ha, 2nd harvest – 3.845 t/ha, total harvest – 7.626 t/ha
  • Perfect for mixtures with grasses and clover

• Dry mass yield in the second year of growth – 10.39-10.62 t/ha
• Dry mass yield in the third year of growth – 7.29-12.41 t/ha
• Green mass yield in the II year of growth – 35.88-46.98 t/ha
• Green mass yield in the third year of growth – 38.61-40.44 t/ha
• Days to the first harvest – 46-77
• Resistance to lodging – 9 points (out of 9)
• Winterhardiness – 9 points (out of 9)
• Growth intensity – 7-9 points (out of 9)
• Number of cuts – 3
• Protein content in dry matter – up to 15.1 %

*Official variety tests in Latvia in 2003-2004

• Total annual yield – 11.605 t/ha

• Violations in winter – 3.6 %
• Yield of the 1st year – 12.688 t/ha
• Yield of the 2nd year – 11.152 t/ha
• Yield of the 3rd year – 10.519 t/ha
• Digestibility of the 1st year yield (D value, digestible proteins) – 667 g/kg
• Digestibility of the 2nd year yield (D value, digestible proteins) – 645 g/kg
• Digestibility of the 3rd year yield (D value, digestible proteins) – 709 g/kg
