Abstract

Kudzu, a kind  of  legume   cover  crops  (LCC),   plays  important   roles  in  soil and  water conservation. It is effective  for  inhibiting  erotion,  compaction  and leaching  of nutrients,  as well as to suppress weeds.  Plants growing with legume  ground covers usually show  better nutrition,   growth and yield. Recently,  this cover crops have been widely  used to prevent  the negative effects  and to improve  soil physical  and nutritional  characteristics. As a legume,  bacterial  inoculation   is to enhance  the infection and nodulation activity. A research  to observe  the role of indigenous  Rhizobium   on infection and nodulation  activity of kudzu was carried  out in September  till December 2004.  The research  was done in Regosol  volcanic  soil in Tlatar  Village  of Sawangan in Magelang district of Central  Java. A pot experiment   was arranged in 4x2 factorial    completely   randomized   design  which  was repeated   three times.   The  seedling   innoculation   with  root  nodules  endophytic   bacteria   was  to increase  nodulation  and to enhance  Kudzu  plant growth.   The seedlings  were inoculated  with  1, 2 and 3 ml/pot of grinded  root nodules  of wild plants  containing  endophytic  Rhizobium  sp.  The wild kudzu  plants were taken  from  coastal  sandy  land  of southern   Yogyakarta.   All treated seedlings were planted  in a sterilized  medium  to be compared  to the unsterilized  one in order to examine  the role of indigenous  bacterias. Observation  on bacterial infection activity, nodulation,  and plant growth were taken  at week  4, 6, 8, and  10. All the  datas  were  variance   analyzed   and the  treatments average  were  tested  with 5% level  of Duncan's multiple range test. The  results  showed  that  application   of 2 ml/pot  of innoculum significantly   increased  the infection  activity, nodulation  and plant growth. Sterilized  soil decreased  the infection  activity.   Since the innoculation  of endophytic Rhizobium  sp.  in unsterilized  soil significantly   increased the infection actifity,  nodulation  and plant growth,  so the indigenous  Rhizobium sp. in rhizhosfer  was needed to sinergisticaly  worked  well with inoculum  to increase  infection  activities   and root nodulation.

Abstract

The research to observe the effect of the kinds and thickness of organic mulch toward the population of weeds and melon yield was conducted in Wringin, Purwobinangun, Pakem, Sleman District of Yogyakarta, at February up to May 2004. The research site has the 500 m above sea level altitude and the Regosol soil type. The field experiment was arranged in a single factor Randomized Completely Block Design with three blocks as replications. The treatments of mulch kinds consisted of 8 levels which are: no mulch application, plastic mulch, straw mulch with 4 cm, 8 cm, and 12 cm thickness, bamboo leaves mulch with 4 cm, 8 cm, and 12 cm thickness. The effect of treatments on weeds population suppression, melon growth and yield were observed during the growth period. The result showed that the bamboo leaves mulch with 8 cm thickness and plastic mulch significantly suppressed weeds population until 67 days after planting in compared with the other treatments. Straw mulch and bamboo leaves mulch significantly increased the component of melon yield, but the kind and thickness of organic mulch was not significantly affected the growth and yield of melon.

Abstract

A research to observe  the influence of Rhizobium and Vesicular Arbuscular Mycorrhyzae inoculation  on growth  and yield of Edamame and Wilis varieties of soybeans in Entisol  soil. The research  was conducted  in the green house  of Agriculture  Faculty,  Muhammadiyah   University  of Yogyakarta,  from June to September  2003. The field experiment  was arranged  in 4x2 factorial  Completely  Randomized  Design  (CRD) with three  replications.   The  first  factor  was  inoculation treatment which contains four  levels consisted  of:   (1) without  inoculation;   (2) Rhizobium inoculation;   (3) VAM inoculation   and  (4) Rhizobium-VAM inoculation. The second  factor  was the kind of varieties  namely  Edamame  and Wilis. There were 24 research  units  which  contain  12 polybags  of each unit. The result of  this  research   showed   that  there  was  no  interaction   between inoculation treatments and kinds of  varieties   to all  of  parameters, except the  percentage of mycorrhizae infection.  Inoculation  of Rhizobium  and VAM significantly  increased  the growth and yield of Wilis variety.  The  100 grains  weight  of Edamame   variety  was  23.21  g and  Wilis  variety  was 7.49  g. Inoculation  of Rhizobium  on Wilis variety was more compatible than Edamame.  Endogenus  VAM application on Edamame  variety was more compatible than VAM isolates inoculation.
