Abstract
Georgia is ranked highly nationwide for vegetable production and it is a significant contributor to the state’s economy, generating $1.3 billion in 2023. Sweet corn and short-day onion account for over one-quarter of the value brought by vegetables. While their value has kept pace with national prices, vegetable acreage has decreased in Georgia since 2019. To align with national values, there is a need to increase production efficiency on less acreage. Narrow row planting arrangements are commonly used in agronomic crops to improve production and enhance disease management. We investigated the effects of narrow row planting arrangements with variable in-row space on sweet corn and onion production. We found that narrow skip rows increased marketable yield in sweet corn without compromising ear quality, and that a narrow twin row, high density planting arrangement produced a favorable bulb size distribution with a higher percentage of high-value bulbs in short-day onions.
