KAJIAN PENYEBARAN AIR DI DAERAH PERAKARAN PADA BEBERAPA JENIS TANAH DAN TANAMAN DALAM SKALA LABORATORIUM
ABSTRACT: Knowing about water
distribution in root area is important as one of our reason to give irrigation.
This research was purposed to study water distribution in root area for several
types of soil and plant at laboratory scale. The important parameters observed
were soil physical property, evapotranspiration, water application and storage
efficiency, and water distribution. The result of this research showed that
Inceptisol soil had clay texture, Latosol soil had clay texture, and Andepts
soil had sand clay loam texture. Evapotranspiration for mustard green plant in
middle phase was 1,92 mm/day and for last phase was 0,96 mm/day.
Evapotranspiration for soya bean plant in middle phase was 1,84 mm/day and for last
phase was 1,12 mm/day. Water application efficiency for the three varieties of
soil was between 35,89% and 100% and water storage efficiency was between 9,16%
and 100%. Water distribution for mustard green plant in the three varieties of
soil was between 29,20% and 37,91% and soya bean plant was between 25,95% and
37,05%.
