Abstract: The efficient nutrient management is crucial to achieve crop yield sustainability. Organic manures can play in important role in achieving sustainability. But these manures are bulky in nature and low in nutrient content, hence the replacement is highly required. Green manure, another possible option of providing nutrients to crops from organic sources, but it has got many limitations as it requires crop cycle of about 45-60 days from sowing to breakdown with suitable temperature and optimal moistness after incorporation. The only option available is brown manuring which can of supply almost all nutrients to the crops which are considered advantageous for weed management as well as improving soil properties which ultimately leads to increase crop yield by influencing over all Agroecosystem. Brown manuring combining with pre-emergence herbicide(s) significantly improves the soil physico-chemical properties, growth and ultimate yield of crops, weed control efficiency, nutrient use efficiency and the net return with B:C ratio. Impact of Brown manuring on Agroecosystem is reviewed in the present study.
