View larger version (15K): [in this window] [in a new window]   Fig. 1. Row spacing and flowering period effects on boll set rate. Data combined over 2000 and 2002. Each flowering period was 5 d in length, with the first period beginning on the earliest date of bloom for any harvested boll in any plot. Averaged over 2000 and 2002, flowering periods 1, 2, 3, 4, and 5 represent 50 to 54, 55 to 59, 60 to 64, 65 to 69 and 70 to 74 days after planting (DAP), respectively. Within flowering periods, significant differences among row spacings were found only within flowering period 2, during which the number of bolls set m–2 was significantly greater in the 19-cm than in the 76-cm row spacing. Data from the Texas Agricultural Experiment Station Farm, Burleson County, Texas.

Each flowering period was 5 d in length, with the first period beginning on the earliest date of bloom for any harvested boll. Averaged over 2000 and 2002, the time span covered by the flowering periods was 50 to 74 days after planting (DAP). Data from the Texas Agricultural Experiment Station Farm, Burleson County, Texas.
