Scope and strategies of intercropping green manures crops in rice – A review

Green manuring has been practiced by farmers and accepted as a potential source of organic manure especially in farms where there are not enough animal manures available. However, growing a crop of green manure exclusively for the purpose of green manuring, warrants farmers to set apart land, labour, time and inputs which is considered as a major constraint amongst them. Hence the practice of raising green manure crops as intercrops in rice would be appreciated as a viable alternative to overcome the difficulty. Past research available on the aspects of intercropping green manure crops with rice, the potential green manure crops for intercropping and their effect on rice growth and yield are reviewed here under.
