Spinach Trial Yield Data - Variety Trial
The variety trial is located at four locations and will continue until the spinach starts to bolt, likely sometime in April. The following charts show the yields for each variety at each location through January. Although the data show some emerging trends, any conclusions will have to wait until statistical analysis of the data is completed at the end of the trial. Yields are shown on the basis of total pounds per 44' x 3' bed. The first chart below shows the harvest dates so far at each of the four locations. The yield trial plots are covered with frost blanket but receive no supplemental heat or light. As such, the spinach went dormant toward the end of December.
WARNING: The data shown in the charts below are preliminary. No conclusions should be drawn until the trial is over (sometime in April) and full statistical analysis has been completed.
The variety trial is evaluating the yield of six different varieties of spinach when direct seeded on September 15 (first chart below) and when transplanted on September 30 (second chart below).
Spinach Trial Yield Data - Heat and Light Trial
The heat and light trial is located at three locations and will continue until the spinach starts to bolt, likely sometime in April. Within each high tunnel we have three low tunnels each with a different heat treatment: no heat, maintain 32F minimum, maintain 45F minimum. Half of each high tunnel receives 12 hours of supplemental LED light. Within each heat/light combination there are 3 replications of planting date: direct seeded on Sept 15, plugs transplanted mid-October, direct seeded on Sept 30, and plugs transplanted late-October. Corvair is the spinach variety. The charts below show the yields through January. Note: although there are interesting trends emerging no conclusions will be reached until after the statistical analysis is completed at the end of the trial.
WARNING: The data shown in the charts below are preliminary. No conclusions should be drawn until the trial is over (sometime in April) and full statistical analysis has been completed.
