Description A field experiment conducted in an Alfisol at ICRISAT
consisted of three land configurations namely ridges, broad bedfurrow
(BBF) and flat. Two varieties of groundnut namely,
ICG(FDRS)10 and ICGS 11 were tested. The results indicated that
lowest bulk densities of 1.41, 1.44, 1.46 and 1.48 g cm.' were
observed in BBF at 30, 60, 90 and 145 DAS respectively as compared
to the flat. Highest soil moisture contents of 0.766, 0.683, 0.660
and 0.543 g/g were observed in BBF at 30, 60, 90 and 145 DAS
respectively as compared to the flat. The penetration resistance
was found to be lower in BBF by 9.3 and 15.5 kg cm.2 than that in
ridges and flat respectively. The total porosity of the soil in
BBF was found to be higher by 4.0 and 8.3 per cent than in ridges
and flat respectively. Maximum oxygen content of 21.84 per cent
was observed in BBF as compared to other land configurations.
Maximum pod yields of 4,219 and 3,388 kg ha.' were recorded in BBF
with ICG(FDRS)lO and ICGS 11 varieties respectively. The mean
increases in pod yields observed in BBF were 11.9 and 20.5 per cent
when compared to ridges and flat respectively. The increased pod
yields observed in BBF might be due to increase in soil moisture
retention, decreases in bulk density and penetration resistance.
