The objective is to leave as many residues as possible in order to increase soil organic matter and to spread them as evenly as possible. Especially in environments where decomposition is fast and where the amount of residues is low it is not recommended to chop the residues. Rotavator is important machine which break the soil and crop residues and mix so that eventually. Conservation agriculture crop can be increased climatic resilence, food security, soil nutrion, energy reduction and income. Presently farmers are facing the problem of labour shortage and drudgery of farming these are all can be reduced by conservation tillage practice.
