KAJIAN PENGARUH LAMA PENGGENANGAN TERHADAP KUALITAS AIR DAN SIFAT FISIK TANAH ANDOSOL SERTA PERTUMBUHAN TANAMAN TOMAT (Lycopersicum esculentum Mill.)

Edit
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.
Key word: overflowing, tomato plants, water quality, soil physical properties
