6.1 INTRODUCTION
The rice (
Oryza sativa
)-wheat (
Triticum aestivum
) cropping system
(RWCS) occupies about 28.8 million hectares (m ha) in five Asian coun-
tries, namely, India, Pakistan, Nepal, Bangladesh, and China (Prasad
2005). These five countries represent 43% of the world population on 20%
of the world's arable land (Singh and Paroda 1994). In India, RWCS oc-
cupy 12 m ha and contributes about 31% of the total food grain produc-
tion (Kumar and Yadav 2006). Similarly in China, RWCS occupies about
13 m ha (Jasdan and Hutchaon 1996) and contributes about 25% of the
total cereal production in the country (Lianzheng and Yixian 1994). Thus,
