Dry matter accumulation of two cotton varieties (XLZ42 and XLZ45) in various treatment groups: 1 and 10 days before the first irrigation (T1, T10, respectively) and 1 day before the second irrigation (E1) after seedling emergence, during 2015–2017. The control group (CK) had film mulching throughout the growth stages. Bars are means ± standard deviation (n = 3)
