Abstract

Red acid soils in humid tropic generally have high rainfall in this area. Including acid soils in Indonesia, the average annual rainfall more than 2000 mm which occurred in the rainy season for six months. Mismanagement of excess water will adversely affect the growth of plant. Waterlogging occurs when the amount of rainfall exceeded the infiltration of water in the soil. This is the main problem especially for pineapple plant because this plant cannot survive long in conditions of waterlogging for a long period. This research want to know the effect of waterlogging on soil chemical properties and the second, to know the pineapple resistance to waterlogging, and its effect on the growth of pineapple root. This experiment was conducted at the location of Research and Development (R&D) PT Great Giant Pineapple (PT GGP), Lampung, Indonesia along 2 months, from August to October 2016. The experiment design was arranged in completely randomized design with three replication. Waterlogging treatment is treatment by adding water into the polybag until saturated and let the water flooded up to 2 cms from soil surface. There are 6 treatments: W0: no waterlogging (maintain soil humidity in field capacity) (control), W24: waterlogging 1x24 hours, W48: waterlogging 2x24 hours, W72: waterlogging 3x24 hours, W96: waterlogging 4x24 hours, W120: waterlogging 5x24 hours. The research showed that waterlogging 1x24 hours can increased soil pH and decreased exchangable aluminium in the soil significantly different, the second, waterlogging can increased iron in the soil and significantly different on 5x24 hours and the third, waterlogging star 2x24 hours can inhibit root growth of pineapple
