Abstract

Statistical information suggests a substantial increase in area under irrigation, under rice and wheat, and in use of chemical fertilizers in Asia. However, a slowing down in growth of productivity of rice and wheat has been reported in recent times. In the past, legumes occupied a significant area in the Indo-Gangetic Plain (IGP) but the area has declined due to the more remunerative and relatively more stable cereals. However, legumes still have a potential role in sustaining productivity of rice- and wheat-based systems. Atmospheric nitrogen (N) fixed by legumes in symbiosis with root nodule bacteria potentially meets much of the N demand of the legume and can contribute to the N requirements of subsequent crops...
