FERTILIZATION STRATEGY TO INCREASE RICE GROWTH AND PRODUCTION UNDER TWO FLOODING CONDITION ON TWO LOWLAND SWAMP TYPES
Abstract: Flood is general
phenomenon found in most areas of Indonesia. This can obstruct rice crop
cultivation on lowland swamp areas. Fertilization strategy is one of the
efforts to increase rice crop growth and production on flooded condition. The
objective of this research was to determine the best fertilization strategy on
vegetative stage related to rice crop growth and production under flooded
condition at two types of lowland swamp. The experimental design used in this
research was split-plot design with three replications. The main plot was
fertilization treatment consisting of P1 = base fertilization, P2 =
fertilization before flooded, P3 = fertilization after flooded and P4 =
fertilization before and after flooded. The subplot was rice variety which
consisted of V1 = Inpara 3, V2 = Inpara 5, V3 = IR 64 and V4 = Ciherang. The results showed that fertilization
strategy was capable of increasing rice crop growth and production under
flooded condition at two types of lowland swamp. Rice variety Inpara 5 added with fertilizer
before flooded on shallow-backswamp and fertilizer addition before and after
flooded on middle-backswamp was the best treatment that had produced rice yield
with magnitude of 4.48 and 3.43 ton per hectare, respectively.
