Abstract

[THE USE OF OIL PALM EMPTY-FRUIT-BUNCHES COMPOST AS THE SUBTITUTE FOR NPK FERTILIZER IN THE OIL PALM PRE-NURSERY]. Compost of oil palm empty fruit bunches (OPEFB) is rich in nutriets needed to support the plant growth and offers as the substitute for chemical fertilizers. The purpose of this study was to determine the rates OPEFB compost and NPK fertilizer applications on the best suited for the growth of oil palm seedlings during pre-nursery. The OPEFB compost at 50, 100, and 150 g/pot was applied in factorial combination with with NPK at 0.0, 2.5, and 5.0 g/pot. Data were collected for seedling height, stem diameter, leaf number and leaves greenness. Higher leaf number was observed when OPEFB compost applied at 100 or 150 g/plot with or without additional NPK. Seedling height, stem diameter, and leaves greenness were increased with the application of OPEFB compost at 50 g/pot but no further increase with the additional rates. Additional application of NPK only increased the leaf greenness.
使用空棕榈油堆肥代替油棕初苗圃的NPK肥料
[在油棕苗圃中使用空果串堆肥代替氮磷钾肥料]。油棕空果串(OPEFB)的堆肥富含支持植物生长所需的营养物质,可以替代化学肥料。本研究的目的是确定育苗期最适合油棕幼苗生长的OPEFB堆肥和NPK肥料的施用量。50、100和150 g/盆的OPEFB堆肥与0.0、2.5和5.0 g/盆的NPK作因子组合施用。收集了幼苗高、茎粗、叶数和叶片绿度的数据。施用100或150 g/块的OPEFB堆肥,在添加或不添加氮磷钾的情况下,叶片数较高。施用50 g/盆的OPEFB堆肥可增加幼苗高度、茎粗和叶片绿度,但不随添加量的增加而增加。氮磷钾的额外施用只增加了叶片的绿度。
