Other claims from this paper (10)
- Intervention effect Early or mid-October sowing dates did not affect total, jumbo or medium onion yields.
- Intervention effect Late October sowing (29 Oct. 2001) did not produce sufficient onion stand or yield to warrant harvesting.
- Intervention effect Variety had no effect on yield of direct-seeded onions.
- Intervention effect Seedstems were significantly greater with the early October sowing date than with mid- or late-October sowing dates across all varieties.
- Intervention effect Variety did not significantly affect plant stand or plant spacing of direct-seeded onions.
- Intervention effect Fertilization treatments of 150 or 195 lb/acre nitrogen did not affect total or medium onion yields.
- Intervention effect Calcium nitrate as the primary N source at 195 lb/acre total N gave the highest jumbo onion yield in only one year, not differing from some treatments at 150 lb/acre N.
- Intervention effect Fertilization treatments did not affect seedstems, plant stand or plant spacing of direct-seeded onions.
- Recommendation Growers should direct seed onions in southeastern Georgia in mid-October, plus or minus 1 week depending on field accessibility.
- Recommendation Current fertilizer recommendations for transplanted dry bulb onions, including 150 lb/acre N, should be followed for direct-seeded onions.
