This study was conducted during 2006-2009 at Shaheed Gundadhoor College of Agriculture and
Research Station, Kumhrawand, Jagdalpur district Bastar (Chhattisgarh) under different rainfed
farming situations. In upland farming situation, broadcasting (dry aerobic) + biasi + recommended
fertilizer (80-50-30 kg ha-1 of NPK) + In-situ green manuring with sunhemp was found efficient
with respect to significantly higher mean grain yield (1.83 t ha-1), highest benefit cost (B:C) ratio
(1.52 Rs. per Re.) and maximum rain water use efficiency (RWUE) of 1.59 kg/ha-mm. Under medium
land situation, line seeding (dry aerobic) + recommended fertilizer (80-50-30 kg ha-1 of NPK) + in
situ green manure incorporation by paddy weeder and weed control was found effective with
significantly higher mean grain yield (3.08 t ha-1), highest B:C ratio (2.28) and maximum RWUE
(2.51 kg/ha-mm). However, under lowland situation broadcasting + biasi (dry aerobic) + RDF
80:50:30 kg ha-1 of NPK + in-situ green manuring with sunhemp was recorded efficient with a mean
maximum grain yield of 5.76 t ha-1, followed by line seeding (dry aerobic) + RDF 80:50:30 kg ha-1 of
NPK + Post E weedicide with mean grain yield of 5.74 q ha-1 and line seedling (Dry aerobic)+ RDF
80:50:30 kg ha-1 of NPK + in-situ GM incorporation by paddy weeder & weed control with a
marginally lower yield of 5.69 t ha-1. The highest B:C ratio was found in Line seedling (Dry aerobic)+
RDF 80:50:30 kg ha-1 of NPK + In-situ GM incorporation by paddy weeder & weed control. The rice
crop establishment methods did not gave any effect on relay crops because the sowing of relay
crops is done as soon as the free water disappears. This time is almost same for all the treatments.
However, field pea and lathyrus was recorded comparatively higher yields indicating their
effectiveness in soil moisture utilization. Field pea was superior with a yield of 1.47 t ha-1 and B: C
ratio of 6.16.
