Experiments on Groundnut/Sorghum Intercropping Systems
Since RMP 15 performed better than others it was intercropped with sorghum in various
sowing patterns (Table 2).

Intercropping groundnuts with sorghum had a negative effect on production. However,
groundnut grown in juxtaposition to sorghum performed better than when it was superposed
on sorghum.
In another trial, groundnut varieties, 2 IE (90 days) and RMP 15 (120 days), were grown in
juxtaposition to sorghum (Table 3).

Groundnut yields remained low, irrespective of the variety. The early-maturing variety had
a slight advantage over the late variety. This result is contrary to that found in Table 1.
