ABSTRACT Cotton ( Gossypium hirsutum L.) yield Y ) generally depends on the plant height H ), leaf area index (LAI), dry matter accumulation D and water consumption W of entire growing period. Growing degree days (GDD) is an important meteorological factor affecting these growth indicators. This paper establishes a relative logistic model , LAI based R GDD analyses spatial variability characteristics parameters. The influence parameters harvest (HI) are determined using grey relational analysis. A series cotton mathematical models then proposed maximum (LAI max . results reveal that rates were maximised when 0.43, 0.56 0.67, respectively. coefficient variation parameter ranges from 0.1 to 1.0, indicating medium variability. HI reach values 0.343 7236.464 kg/ha for 5.046 5.949 cm 2 /cm corresponding required as 489.606 mm 497.978 mm, while use efficiency (WUE) 14.686 kg/(ha·mm) 14.532 kg/(ha·mm), Furthermore, range 2.719 7.225 455.957 642.688 study provides scientific foundation enhancing WUE in agricultural regions Xinjiang. methods enable prediction with improved accuracy.
