Note: This first harvest was conducted on March 2, 2009, 70 days after direct-seeding.Note: Yield assessment based on the average weight of 5 heads per plot. Plant spacing was 2 ft betweenplants within rows, and two rows per bed, spaced 1 feet between rows, and planted in a staggeredarrangement.Note: Per acre yields were calculated based on an estimated 10,850 plants per acre, based on double rowbeds, and 4 ft between beds.Note: “Acutal yields” take into consideration the percent plant stands. For instance if, based on headweight, and total potential no. of plants per acre, if the potential yield was 10,000 lbs, but only 70%plant stand, Actual Yields are listed as 7,000 lbs/Acre (showing that 30% of the plants failed toproduce).
