Abstract

Two field experiments were carried out during summer seasons of 2017 and 2018 at the Experimental Farm, Faculty of Environmental Agricultural Sciences, Arish University, Egypt to study the effect of three levels of irrigation (100, 80 and 60% of irrigation water requirement) and three types of soil amendments (without, gypsum and pressed olive cake) and their combinations on growth and yield of sweet pepper (Capsicum annuum L. cv. “Top Star”) crop under El-Arish region conditions. Plants were irrigated using drip irrigation system. The highest values of all studied traits; viz., vegetative growth, plant fresh and dry weights, yield of grad A and B and total yield  were recorded with using 100 %  followed by 80% irrigation level both + pressed olive cake that followed by applying 80% irrigation level + gypsum as soil amendment, respectively in both growing seasons. While the lowest values were obtained by application 60% of water requirements with or without using soil amendments.
