Green Gold Program (Optimum Alfalfa Harvest Date)

The Green Gold Program helps producers maximize their hay quality by harvesting their alfalfa stand at the optimum time!

Receive tested results!

E-mail John McGregor, Green Gold Program Coordinator, to receive tested results twice weekly from numerous regions across the province and know the best window to cut your hay.


For over 20 years, the Green Gold Program has been used to help predict the date when pure alfalfa stands are at optimum quality (150 RFV). Due to unusual environmental conditions (cool weather and extreme warming conditions), we have seen alfalfa reach optimum quality well before the traditional early bloom (10% flower) stage.  In most cases, had producers waited for the crop to show these signs, harvest would have been delayed by up to 2 weeks and RFV would have been in the 110 range.


  • Samples are taken at 8:00 a.m., twice a week (Mondays & Thursdays) and delivered to the lab before 11:00 a.m.
  • Regional results are emailed to subscribers twice each week through Coordinator John McGregor, posted here and communicated via the Manitoba Co-operator, Radio Southern Manitoba, and the Carillon News.
  • Approximately 500 producers and industry people receive this information, including alfalfa producers, dairy, beef and sheep producers.

Assessing Frost in Alfalfa - Alfalfa growers are assessing their crop for frost damage after temperatures dipped below zero in southern Manitoba in the mornings of June 2nd and 3rd. A light frost of -1 to -2 C will not cause major damage to the crop, explains the Manitoba Forage & Grassland Association’s John McGregor. Read the full article posted in Pembina Valley Online here.

Assess frostbitten alfalfa, prepare to mow - Alfalfa growers whose stands are hit by frost — as growers saw in southeastern Manitoba this past Sunday and Monday mornings — will need to assess and get ready to mow if need be. Read the full article posted in Grain News Online here.
