2011, 1(4): 106-108.

Abstract(604) [PDF 1773KB](4)

Abstract:
Residue management is an important for maintaining appropriate soil texture and structure while aiming for higher crop yields.Excess tillage generally results into soil erosion，compaction and deterioration of soil structure，which consequently reduces its productivity.Hence current tillage trend is shifting from intensive to the reduced or conservation tillage practices.On the other hand，farmers in agricultural economy based developing countries have been following the open field burning practice for managing crop residues.These crop residues however could be potentially utilized for increasing soil fertility.In the context of present shifting trend from conventional to conservation tillage，farmers are looking for options of appropriate machinery to handle and manage heavy crop residues left after harvesting of crops like paddy and sugarcane.As residue management is a time consuming and laborious job，introduction of appropriate machinery may accelerate the adoption of conservation tillage.Disc implements，being the most versatile implements，can be used over the wide range of soil and various operating conditions.Moreover，driving tillage disc may play an important role in adopting and promoting conservation tillage practices. This paper reviews various tillage equipment used for residue management，their advantages，work quality and related issues，and confirms how powered discs are effective in residue management.
