Conclusion
The yield of each rabi crops significantly decreased when sown after Gitesh (long duration rice
variety) as compared to sowing of the same rabi crops after Kalanklata (medium duration
variety). The system yield of the cropping sequence reduces when sowing was delayed from
1 st of December to 15 th Dec with flood and sprinkler irrigation, respectively. The sowing date
had an impact in the yield and yield attributes of all the rabi crops irrespective of the irrigation
treatments and the sprinkler irrigation gives better yield than the flooded irrigation for all the
rabi crops. The system yield comes to be higher in case of all the rabi crops preceded by
medium duration kanaklata variety, which indicates that the sowing date had an impact in the
rabi crops irrespective of the irrigation types applied. The lowland areas can be used for
growing of the rabi crops with life-saving irrigation depending on the dry spells occurred after
