	<span lang=\"EN-US\"><span style=\"font-family:Verdana;\">Mechanically
post-harvest puddled rice field has stubbles that often delay timely planting
of winter wheat crop. Zero tillage increased the net return by decreasing the
unwise tillage operations and labor charges. Keep in view, a randomized
complete block design experiment in a split plot arrangement was conducted with
four tillage system [conventional tillage, CT; deep tillage, DT; zero tillage
with zone disc tiller, ZDT; and happy seeder, HS] in main plots and five nitrogen
levels [0, 75, 100, 125, and 150 kg<span style=\"font-family:Verdana, Helvetica, Arial;white-space:normal;background-color:#FFFFFF;\">&amp;middot;</span>ha</span><sup><span style=\"font-family:Verdana;\">-1</span></sup><span style=\"font-family:Verdana;\">] in subplots during 2009 to
2010 and 2010 to 2011 cropping seasons. Results showed that in 2009-10 and
2010-11 grain yield (4.6 Mg<span style=\"font-family:Verdana, Helvetica, Arial;white-space:normal;background-color:#FFFFFF;\">&amp;middot;</span>ha</span><sup><span style=\"font-family:Verdana;\">-1 </span></sup><span style=\"font-family:Verdana;\">and 5.7 Mg<span style=\"font-family:Verdana, Helvetica, Arial;white-space:normal;background-color:#FFFFFF;\">&amp;middot;</span>ha</span><sup><span style=\"font-family:Verdana;\">-1</span></sup><span style=\"font-family:Verdana;\">) in DT
and (4.5 Mg<span style=\"font-family:Verdana, Helvetica, Arial;white-space:normal;background-color:#FFFFFF;\">&amp;middot;</span>ha</span><sup><span style=\"font-family:Verdana;\">-1</span></sup><span style=\"font-family:Verdana;\"> and 5.8 Mg<span style=\"font-family:Verdana, Helvetica, Arial;white-space:normal;background-color:#FFFFFF;\">&amp;middot;</span>ha</span><sup><span style=\"font-family:Verdana;\">-1</span></sup><span style=\"font-family:Verdana;\">) in HS were
significantly higher compared with CT and ZDT. Significantly, maximum leaf area index (5.18 and 5.24) and
crop growth rate (12.14 g<span style=\"font-family:Verdana, Helvetica, Arial;white-space:normal;background-color:#FFFFFF;\">&amp;middot;</span>m</span><sup><span style=\"font-family:Verdana;\">-2</span></sup><span style=\"font-family:Verdana;\"><span style=\"font-family:Verdana, Helvetica, Arial;white-space:normal;background-color:#FFFFFF;\">&amp;middot;</span>d</span><sup><span style=\"font-family:Verdana;\">-1</span></sup><span style=\"font-family:Verdana;\"> and 13.15 g<span style=\"font-family:Verdana, Helvetica,
