Abstract

Abd El-Aleem, W. H., Hamed, E. S. & Toaima, W. I. M. (2021). Effect of blue green algae extract on three different curly parsley varieties under Sinai conditions. Bulg. J. Agric. Sci., 27 (5), 887–895

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.
