Abstract
Climatological factors and the boll load from the first fruiting cycle were evaluated as primary causes for low boll retention by cotton (Gossypium hirsutum L.) during midseason. Boll retention was permitted from incipient flowering, or after June 26, July 15, July 30, or August 14, by the daily removal of flowers. Boll retention was greater than 75% initially, but decreased to less than 50% after bolls equivalent to 500 to 1,200 kg lint/ha (1 to 2 bales/acre) were retained and less than 20% after bolls equivalent to 700 to 1,300 kg lint/ha (1.25 to 2.25 bales/ acre) were retained. The fruit load was the primary cause for low boll retention and cessation of flowering during midseason. No direct relationship between low boll retention and high maximum or minimum temperatures or high relative humidity was observed.
