This study was conducted at the Agricultural Experimental Research Station located at Hada Al-Sham, King Abdulaziz University during two successive seasons (2015-2016 and 2016-2017) to study the effects of different organic fertilizers (cow manure, sheep manure, cow manure + barley straw and sheep manure + barley straw) and NPK (20:20:20), under two irrigation methods (surface and subsurface drip irrigation), and three water supply rates (100%, 80% and 60%), on growth components of Cabbage (Brassica oleraecea L) and soil content of the macro-elements N, P, K in split- split plot design in 4 replicates .The subsurface drip irrigation (SDI) system dominated the surface drip irrigation (DI) system, and the 100% irrigation water rate was better than 80% and then 60%, and the NPK dominated organic fertilizers , seconded by sheep manure, then cow manure , then sheep manure + barley straw, then cow manure + barley straw, as regards mean values of all cabbage growth components of, head ,stem, leaves , root, and total plant fresh and dry weight and the highest soil content of NPK .
