Abstract
Publisher Summary This chapter reviews some new research in green manuring of wetland rice. It discusses the agronomic advantages of applying green manures to wetland rice as a source of both nitrogen and organic matter. Changed physical, chemical, and biological behavior of soils because of organic matter addition through green manuring, and consequential influence on the availability of several plant nutrients are also reviewed in the chapter. Green manure crops can be leguminous as well as nonleguminous and can be grown in situ or brought from outside as cuttings of trees and shrubs. The latter practice is called “green leaf manuring” (GLM). Fast-growing leguminous green manure crops have a tremendous potential in harnessing the atmospheric N 2 , and act as substitute for fertilizer N in wetland rice. There is a large range of drought- and waterlogged-tolerant green manure species. The most studied benefit of leguminous green manure is its contribution to N nutrition of the rice crop. Considerable evidence has accumulated that the use of leguminous green manure can significantly raise rice yields.
