ABSTRACT

Field experiments were carried out during late rabi/early summer seasons of 1996-97 and
1997-98 with four tillage practices as main plots and three IW/CPE ratios as sub plots in strip
plot design with four replications. The seed yield and yield attributes recorded by ploughing
twice with country plough followed by working twice with power tiller rotovator; and tractor
tilling with cultivator twice followed by rotovating twice with power tiller was comparable and
significantly superior to that recorded with tractor tilling with cultivator twice followed by harrowing
twice with tractor drawn offset disc harrow; and ploughing twice with country plough alone.
Among the IW/CPE ratios, irrigations scheduled at 0.4 IW/CPE resulted in significantly higher
seed yield than that of 0.6 IW/CPE ratio and yield in the latter treatment was significantly
higher over that of 0.2 IW/CPE ratio.
