An experiment conducted at Amawakhas Nyaypanchayat, Kushinagar district of U.P. Under
National Innovation in Climate Resilient Agriculture (NICRA) project for the scrutiny of the
impact of zero tillage over conventional tillage during the year 2012 to 2016. Zero tillage
reduces cost of tillage and irrigation, which results in increase of yield through possible
improvement in sowing time and enhanced water use efficiencies. The experiment results
revealed that performance of zero tillage was found superior over conventional tillage in
context of yield attributes viz. spike length, no. of spike m -2 , no. of grain spike -1 except test
weight. Therefore, the mean yield was estimated higher in zero tillage i,e 40.55 qha -1 which
was 8.22 % higher than conventional tillage i.e 3722 kg ha -1 . On average zero tillage saved
