چکیده

The effects of low-irrigation and fertilization systems on some chemical properties of plant and soil under the cultivation of barley were investigated by a split-plot experiment conducted on the basis of a Randomized Complete Block Design in 2007-2008. The main plots were composed of three irrigation levels: no-stress, moderate stress and severe stress. The subplots were composed of six fertilization regimes including no-fertilization, the application of Barvar-2 + nitroxin, the application of vermicompost, 50% chemical fertilizer + 50% vermicompost, 50% chemical fertilizer + 50% (Barvar-2 ferti[1]lizer + nitroxin), and the application of chemical fertilizer. It was found that the mixture of chemical and organic fertilizer increased soil P content more than other fertilizer combinations. Furthermore, the mixture of fertilizers increased plant N concentration more than other fertilizer treatments. The treatments containing vermicompost increased soil organic C, N and P under all stress levels more than other treatments. Also, this treatment gave rise to higher N concentration in plant under drought stress. Under normal irrigation conditions, biofertilizers increased soil and plant P content more than other fertilization regimes.
