Note: SPF = spikelet fertility, SW = seed weight, YLD = grain yield, 1RSD = rice straw dryness biomass at panicle initiation stage
and 2RSD rice straw dryness biomass at maturity and Plong = panicle lengt
Rice plants grown with line-sown
stylosanthes
was
shorter and it was less rice straw dryness biomass than
rice plants in the other treatments in an average from
two locations (Table 3) and there was more rice straw
dryness biomass at NAFReC, if compare to farmer’s
field (Table 2).

Grain yield component were very important for increase
of rice productivity as this result was shown it was high
yield when intercropping between rice and
stylosanthes
was line sown and also significant difference between
line and broadcast sowing as; more
stylosanthes
dryness
biomass in line sown plot (Figure 1), but it was non
significant between location and treatment interaction
(Table 2) and only 4 percent of spikelet fertility in the
plot of
stylosanthes
was line sown was provide higher
grain yield of rice or yield advantage about 1074 kg/ha, it
also highly significant difference by analysis of variance
and standard error at 98.5% (Figure 2).
