A pot experiment was carried out in the glasshouse of National Research Centre, Giza Dokki, Egypt during two successive seasons 2020 and 2022 to examine the influence of KCl spraying treatments and duration of irrigation on Chlorophytum growth parameters and chemical contents, in three sprays at concentrations (0, 150, 200 and 250 ppm) and water regime (4, 7 and 10 days) with the control. However, the highest value of these characters (Plant height, plant volume, cluster number, K %, and carotenoids content) obtained at 4 days intervals while root length, fresh and dry weights of shoots, protein, and N % were showed the highest increments by 7 days irrigation period, as well as carbohydrate % and photosynthetic pigments contents by 10 days with insignificant difference in flowering, and chemical characters. In addition, the KCl treatments showed insignificant effect. It caused an increase in previous vegetative measurements and chemical constituents such as total chlorophyll and mineral elements (Na, N, P and K) analysis at 200 and 250 ppm compared with control. The purpose of study is to know more about the effects of KCl and water periods on plant development and chemical components.
