|Organic Okra Variety Trial
Sixteen organic varieties of okra were
included in this years study. Plots
were sown on May 24 with a Hege 1000 Series Drill/Planter on 30 inch row
widths. Soil temperature was 78.6 F. Seed was planted at 3/4 of
an inch on a fine, firm seed bed. Each plot consisted of four ten foot rows.
Only the middle two rows were evaluated. Varieties included:
Clemson Spineless 80, Burgundy, White Velvet, Perkins Long Pod, Silver
Queen, Cajun Jewel, Jade, Clemson Spineless (1939), Cow Horn, Burmese,
Star of David, Red Burgundy, Louisiana Green Velvet, Ever Tender, Emerald
Green, and Dwarf Green Long Pod.
Unfortunately, rye grass was used as
cover crop prior to the Okra planting, making weed control extremely
difficult. Due to the late planting because of rain, several of the
replicated plots were lost. Only seven of the varieties survived the
growing season to full maturity.
Pods were harvested by hand on November 6 well after a killing frost.
The pods were allowed to dry naturally and then were threshed with a single
plant cylinder thresher. Seed yields were assessed and evaluated for
each variety. Yields ranged from 200lbs./acre to 1,000 lbs./acre.
The 2004 variety trails will be replicated in 2005.
Varieties were evaluated for germination rate, seed retention, lodging,
branching, plant height, pod length, general disease tolerance, insect
tolerance, and seed yield. All data will be
published in the Midwest Vegetable Variety Trial Report for 2005.
