The tables below are preliminary yield data from three out of four cotton OVT locations and four out of five on-farm locations in Virginia for the 2020 growing season. As many are aware, 2020 was marked with a delayed planting window for cotton with most cotton planted in the state from May 15 – May 25, 2020. July saw below average rainfall for most of the Virginia cotton acreage which delayed development and reduced yields. Following July, rainfall for August – November was above average which resulted in excess growth in late August and September and delayed defoliation and harvest. If you have any questions please contact Dr. Hunter Frame, Field Crops Agronomist at whframe@vt.edu.
