A field experiment was conducted, during 2020 and 2021 growing seasons, on pepper plants (Capsicum annuum L.), under net covered greenhouse conditions. Two factors were studied, (a) organic fertilizers and (b) irrigation levels. The fertilization treatments were: the application of a half dose of mineral fertilizers combined with different types of organic fertilizer i.e., compost, vermicompost and organic manure in rice straw; compared with soil. The irrigation treatments were: three irrigation levels i.e., 70, 85 and 100 % based on reference evapotranspiration (ETo). Both (a and b) factors were distributed in a complete randomized block design with three replicates. Results indicated that both soil temperature and moisture were more suitable for plant growth in rice straw after adding compost under 85% irrigation. Growth parameters (plant length, number of leaves, leaf area, number of branches, stem diameters and fresh and dry weight of plants) were enhanced by using compost under 85% irrigation level. The same trend was obtained in chemical composition of pepper plants i.e., chlorophyll, N, P, K and vitamin C in fruits. The yield of fruits, in rice straw treatment with 85% irrigation level, combined with compost, slightly increased compared with clay soil (control). Water productivity is considered water use efficiency (WUE), was increased in irrigated rice straw, with compost as fertilizer, with 85% of ETo. The study stated that, using affordable agriculture crop residues, as cultivation medium, plus organic fertilizers, instead of mineral fertilizers, it achieved higher sustainable production of green pepper.
