  "abstract": "The experiment was conducted at the Experimental Farm of Faculty of Technology and Development (Ghazala Region), Zagazig University, Sharkia Governorate, Egypt during the winter seasons of 2022-2023 and 2023-2024 , to study the effect of phosphorus as soil application at (50kg/fed. and 100kg/fed.) and foliar spray with phosphorein at (2 mll-1 and 4mll-1) and seaweed extract at (2mll-1 and 4mll-1) on growth and head yield of red cabbage cv Primero. The experiments were set out in a randomized complete block design with three replications. The experiment included 11 treatments as follows: Control (sprayed with tap water), phosphorus at 50kg/fed phosphorus at 100kg/fed, phosphorus at 50kg/fed+ phosphorein e 2mll-1, phosphorus at 50kg/fed+ phosphorein e 4mll-1, phosphorus at 100kg/fed+ phosphorein e 2mll-1, phosphorus at 100kg/fed+ phosphorein e 4mll-1, phosphorus at 50kg/fed+ Seaweed extract 2 mll-1, phosphorus at 50kg/fed+ Seaweed extract 4 mll-1, phosphorus at 100kg/fed+ Seaweed extract 2 mll-1 and phosphorus at 100kg/fed+ Seaweed extract 4 mll-1.The obtained results reveal that, phosphorus 100 kg/fed and seaweed extract at 4 mll-1, increased the number of leaves per plant, plant length (cm), fresh weight of plant and head diameter , as well as total yield.Conclusion: Phosphorus at 100 kg/fed and spraying with phosphorein at 4ml/l ,as well as phosphorus at the same rate with 4mll-1 seaweed extract , increased plant growth characters and total yield and its components of red cabbage",
