Abstract

Bernas et al. 2012. Bamboo Floated-cultivation Model for Upland Kangkung (Ipomoea reptans Poir.)  in Tidal Lowland Area. JLSO 1(2):177-185. South Sumatra Province has a high potential of swampland for expansion of floating agriculture system. Swampland in Palembang, for instance, can be adapted for floating vegetable cultivation.  The experiments on floating agricultural system have been done by using wasted plastic glass, bamboo for rice and glutinous rice with the application of Hycinth and water Fern compost.  The purpose of this research was to build bamboo rafts which were suitable for growing kangkong (Ipomoea reptans).  Previous rafts which contained water saturated soil for rice growing needed to be adjusted for kankong cultivation which prefer unsaturated soil.  Two bamboo rafts were built using four plastic containers in bottom corners.The first raft was filled with soil plus compost (ratio 1:1) and the other was filled only with swamp soil.  Kankong seeds were planted with the distance of 25 cm by 25 cm.  Data were collected weekly and analysed statistically using t-test.  Results showed that when the rafts were supported by two bamboos, plants were died due to excessive water.  Plants grew well after the rafts were supported by plastic containers.   Composting significantly increased plant height, number of leaves, plants fresh and dried weight.  Plant height treated with compost was 38 cm compared to that without compost treatment which was 28 cm. Fresh plant weight was 149 g/bunch with compost treatment and 25 g/bunch without.  Thus, low fertility of swamp soil only required compost to increase nutrients content for plant growth.This research concluded that plant can be cultivated cheaply and environmentally safe in swampland.  Further experiments such as replacing plastic container in raft construction and growing other vegetables on the raft were proposed.

Abstract

Relationship between the Organic Matter Content with Post Harvest Period of Forest Industrial Plant Acacia mangium Willd (Sabaruddin, S.N.A. Fitri, and L. Lestari): Timber harvesting may have significant effects on soil organic matter content through mechanical disturbance, inputs of logging slash, alterations in litter production, and leaching of dissolved organic matter, as well as the alteration of temperature and moisture regimes.  To investigate the effect of post-harvest period of tree harvesting on the dynamics of soil organic matter content, surface soils (0 to 10 cm and 10 to 20 cm) were collected from intact Acacia mangium Willd. plantation (control) and from A. mangium Willd. harvested in 2001, 2002, 2004, and 2006 in four replicates.  Each replicate consisted of composited 4 sub-samples.  Timber harvesting reduced litter accumulation on soil surface.  However, the amount of litter accumulated on soil surface increased as post-harvest period increased.  Timber harvesting significantly (p<0.001) affected soil organic matter content both in 0 to 10 cm and 10 to 20 cm.  The increases in soil organic matter content were significantly correlated (r=0.85; p<0.001 in 0 to10 cm and r=0.62; p<0.01 in 10 to 20 cm) with post harvest period.
