Preface
The essential role of legumes in agriculture is well recognized. The capacity of legumes to fix atmospheric dinitrogen (N2) in partnership with rhizobia provides an input-saving and resource-conserving alternative, thereby reducing the need for chemical fertilizers while enhancing overall crop productivity. As leguminous crops are inextricably linked to the surrounding environment, their mere inclusion in various cropping systems does not always ensure the attainment of the estimated optimal levels of symbiotic N2 fixation in the field. Yield instability represents one important drawback in the development of grain legumes. Thus, special concerns have to be paid to the factors limiting legume growth in order to obtain a more stable level of legume production. Obviously, a major constraint to legume production is low phosphate (Pi) availability in
