| dc.description.abstract | JUNI ARTINA ALBERTA: The study on water distribution in Inceptisol soil planted
with Soybean at different amount of given water, supervised by SUMONO and ADIAN
RINDANG.
Knowing water distribution in soil is important as one of the reason for
irrigation. This research was purposed to study water distribution in Inceptisol soil
planted with soybean at 100%, 80%, 60% field capacity and its effect on soybean
plant’s production. The parameters observed were the characteristic of the soil
physics, field capacity, evapotranspiration, water distribution, dry weight of soybean
plant and pods weight.
The results showed that Inceptisol soil had sandy clay loam texture. The
highest porosity was found at 6-10 cm depth i.e. 63,06%. The lowest porosity was
found at 0-5cm depth i.e. 54,23%. Water field capacity was 47,7% (dry basis).
Soybean plant evapotranspiration at middle growth phase was 1,97 mm/day and the
last growth phase was 1,58 mm/day. The highest water level was found at 6-10 cm
depth i.e. 20,58-32,49% (dry basis). The lowest water level was found 0-5 cm depth
i.e. 20,34-26,63% (dry basis). The dry weight of soybean plant at the middle growth
phase at 100% field capacity was 16,51 g, at the last growth phase was 14,89 g and
pods weight was 13,20 g. The dry weight of soybean plant at the middle growth phase
at 80% field capacity was 14,23 g, at the last growth phase was 11,77g and pods
weight was 10,78 g. The dry weight of soybean plant at the middle growth phase at
60% field capacity was 13,12 g, at the last growth phase was 10,97 g and pods weight
was 8,76g | en_US |
