Abstract
Cotton yield is a function of growth rates, flower production rates and flower and boll retention during the fruiting period. This study, predicting effects of climatic factors during different convenient intervals (in days) on cotton flower and boll production compared with daily observations and collect information about the nature of the relationship between various climatic factors and cotton boll development and the 15-day period both prior to and after initiation of individual bolls. Evaporation, sunshine duration, relative humidity, surface soil temperature at 1800 h and maximum air temperature, are the important climatic factors that significantly affect flower and boll production. Evaporation; minimum humidity and sunshine duration were the most effective climatic factors during preceding and succeeding periods on boll production and retention. There was a negative correlation between f lower and boll production and either evaporation or sunshine duration, while that correlation with minimum relative humidity was positive.
