The efficient nutrient management is essential to achieve crop yield sustainability. Integration of all
possible sources of nutrients can only fulfill the requirement of crops and wherein yield sustainability
can be ascertained. Organic manures can play in important role in this direction. But these manures are
bulky in nature and low in nutrient content, hence the substitution is highly

another possible option of providing nutrients to crops from organic sources, but it has got some
limitations as it is practiced in mainly rice crop that requires a period of about 45-60 days from seeding
to decomposition with proper temperature and optimum moisture conditions after incorporation. The
viable option left behind that is brown manuring as a tool for integrated nutrient management. Brown
manuring is capable of supplying all nutrients to the crops which is also considered beneficial for weed
management as well as improving soil properties.
