In Asia, rice (Oryza sativa L.) is established generally by seedling transplanting in puddled soil. Generally, lands are prepared by 3-4 ploughing and cross ploughing operations followed by levelling in standing water. This traditional method is costly in terms of labour, fuel, time and irrigation water, and is detrimental to soil health (Islam et al., 2014). Adoption of non-puddled transplanting may be a good alternative to soil puddling which has potential to achieve savings in labour, energy, water and time during rice establishment (Islam et al., 2012). Retaining previous crop residues maintains soil microbial activity which can also lead to weed suppression by the biological agents leading to increases in crop yield (Kennedy, 1999). Considerable research work has been done on puddled transplanting, but there is a limited information on the effect of crop residue retention level on the performance of non-puddled transplanting of rice.
