Abstract: The effect of spray with blue green algae extract on the yield of some curly parsley varieties was investigated. The experiment was carried out during the 2016/2017 and 2017/2018 seasons at North Sinai Governorate, Egypt. Treatments were arranged in a split-plot design with three replicates. Foliar spray with three aqueous dilutions of Spirulina platensis extract (0, 5, and 10 ml/liter water) was assigned in the main plots whereas, sub-plots were devoted to the cultivation of three curly parsley varieties (Bravour, Xenon, and Moskrul 2-Petra). Results showed that foliar spray of algae extracts significantly improved herb fresh and dry weights per feddan, chlorophyll content, volatile oil percent, oil yield, and the concentration of 10 ml/liter gave maximum values in this concern. Bravour and Xenon varieties yielded the heaviest herb fresh and dry weights per feddan with non-significant differences in between, while Petra was the lowest. Xenon variety had the significantly maximum oil percent and oil yield. Data of chlorophyll contents within varieties were non-significant. Cultivation of Xenon variety combined with a spray of algae extract at 10 ml/liter was promising for cutting the highest foliage yield with intense flavor and color.
