CHEMBRED F2 from hybrid cottonseed has excellent seedling vigor and is of superior quality. It is the combination of seedling vigor and seed quality that leads to final stands with high plant populations when planting CHEMBRED cottonseed with conventional planting rates. In 1994, we conducted a field study in 4 locations across the Cotton Belt to evaluate the effects of plant spacing on boll distribution and yields. The locations were Maricopa, AZ; Tifton, GA; Rayville, LA; and Priceton, NC. A split-plot design with 4 reps was utilized. The main-plots were varieties CB 232, CB 333, CB 1135 and CB 1233. The sub-plots were plant spacing of 1 plant/ft, 3 plants/ft, 5 plants/ft, and 7 plants/ft. Harvest data revealed that the 1 plant/ft and 7 plant/ft of the full season varieties, CB 1135 and CB 1233 had the lowest yield when averaged across all locations. This, however, did not hold true for the early season varieties CB 232 and CB 333. The early varieties had higher average yields for the 7 plants/ft, although there were no significant differences between any of the planting rates. Within the dense populations of all varieties, plants were taller, bolls were set higher on the plant, and as a result, maturity was delayed. The analysis of seed cost associated with plant spacing assuming a 80 percent final stand, showed that the 7 plants/ft population would double your seed cost and most likely lower your yield. After reviewing yield data, seed cost, and other factors like maturity, it is the recommendation of CHEMBRED to plant for a final stand of 3 to 4 plants/ft using CHEMBRED cottonseed.
