Effect of saline irrigation water on soil salinity, yield and nitrogen fixation by leguminous plants using 15N-tracer technique
2002
Ismail, H.
This study is aimed at analyzing the effects of water and soil salinity on growth, yield and nitrogen fixation by three leguminous plants (chickpea, faba bean and lentil) selected and supplied by ARC, Cairo, Egypt. The experiment was carried out under the greenhouse conditions of MAI, Bari - ItaIy. Crops were cultivated in PVC lysimeters and were irrigated with four water salinity levels. The work was divided into two parts. The first is on germination.The second part evaluates the contribution of N² -fixation. The results obtained prove that the application of the suitable Rhizobium bacteria strains could be beneficial for both plant growth and soil fertility via N² -fixation under salinity condition. Faba bean has the ability to accumulate and utilize more N than chickpea and lentil plants.
