KAJIAN PENGARUH LAMA PENGGENANGAN TERHADAP KUALITAS AIR DAN SIFAT FISIK TANAH ANDOSOL SERTA PERTUMBUHAN TANAMAN TOMAT (Lycopersicum esculentum Mill.)
ABSTRACT: Flooding and
overflowing on horticultural
plant especially for
tomato plants cause
failure of vegetative and
generative growth.The extent to
which tomato plants tolerance if
grown in andosol soil
to overflowing and
flooding need to be studied. This
research was aimed to
examine the Effect of
Overflowing length on the water
quality and soil physical properties of andosol together with
tomatoe plant growth. The result of the research showed that evapotranspiration
atn beginning of growth of 15 days since plant (dsp) was 1,79 mm/day, on active
growth (16-45 dsp) was 3,45 mm/day, on maximum growth (46-75 dsp) was 3,45
mm/day and the end of growth (>75 dsp) was 2,41 mm/day. Water quality that unfavorable
effect towards the growth of tomato plants for 2 days in overflowed conditions
and overflowed until the plants death was dissolved oxygen. Dissolved oxygen
for 2 days in overflowed conditions was
1,98 ppm and for overflowed conditions
until the plants death was 1,68 ppm.Soil Physical properties that unfavorable
effect towards the growth of tomato plants for all conditions was soil
temprature. Soil temprature for 2 days in overflowed conditions was 27,83oC,
for overflowed conditions until the plants death was 28,25oC and for spacey
capacity conditions was 27,85oC. For 2 days in overflowed conditions the soil
salinity was over the restriction limit which was 5,8 mS/cm. Blossom production
of tomato plant on spacey capacity conditions was 27 blossom/plant, for 2 days
in overflowed conditions was 17 blossom/plant and for overflowed conditions
until the plants death has not blossom.
