%X During the past three decades, the rice-wheat cropping systems (RWCS)
in India significantly contributed to enhancing food grain production and
achieving food self-sufficiency and food security. The production system
now is under threat due to stagnating or declining total factor
productivity. Legumes can play a significant role in enhancing the factor
productivity of this most important and productive production system in
the country. Ironically, rice and wheat have replaced the principal
legumes over a period of time. With the availability of high-yielding and
short-duration varieties of important legumes, there is a need to
incorporate them in RWCS to improve the sustainability of the system so
as to meet future food grain demands without degradation of the natural
resource base.
