Abstract:
This study was carried out in the General Commission for Scientific Agricultural Research (GCSAR) at Homs Agricultural Research Center, during 2020/2021season, in order to evaluate the effects of vermi tea foliar application on some local Chenopodiaceae vegetables (beetroot, spinach, and chard) compared with NPK fertilization and control. Vermi compost tea 1:10 w/v was sprayed two times, the first at 4 true leaves stage and the second after 15 days. The experiment was carried out in randomized complete block design with three replicates. Results showed that there were no significant differences between tea spraying and NPK treatment in beetroot studied traits (plant height, leaf number, leaves wet and dry weight, roots wet and dry weight, and total sugars in leaves), and for spinach (plant height, leaf number, leaves wet and dry weight, leaf area, and total sugars in leaves), while NPK treatment surpassed significantly on tea spraying in chard in all studied traits. In three plants the spraying of vermi tea surpassed significantly on control without fertilization. This study concluded that vermi compost foliar application 1:10 (w/v) can be used in beetroot and spinach fertilization without any chemicals. But in chard this study would be continue in higher concentrations to replace chemical fertilization partially.
Key words: Vermi compost, Growth, yield, Beetroot, Spinach, chard, Chenopodiaceae.
