Northeast Texas Cotton Row Spacing By Plant Population Evaluation - 2019

Rising costs have forced cotton producers to look for ways to maintain yields while reducing input costs. Producers have considered different varieties, seeding rates and row spacing. However, poor stands resulting in lower than intended plant populations and could reduce producers’ profitability. Study was conducted at the CCRI Farm in Fairlie, Texas. 4 replications of 2 row by 30 ft plots of DeltaPine 1646 B2XF were planted at 60,000 plants per acre on June 7, 2019. High soil moisture levels negatively impacted stand emergence. After emergence, plots were thinned to the desired planting rate and row spacing with plots thinned to final stand by June 19, 2019. Seeding rates of 35,000 plants per acre and 50,000 plants per acre were assessed by 30” skip row, 30” row, 40” row and 60” row spacing. Plots were side-dressed on row with 10 gallons of 10-34-0 per acre. Plots were side-dressed on row with 100 units N as ammonium nitrate on July 17, 2019. Rows were harvested beginning in October. Yield data to follow.
