Abstract
Nutrient sources and availability from fertilizer is one of the important factors which affect fodder plant growth and production. This
experiment was investigated the effect of enriched phospho-compost application on the growth and phosphorous content of Setaria splendida
Stapf. This experiment was arranged in Completely Randomized Design CRD with 4 treatments and 5 replicates. The treatments were R0 = Rock
Phosphate, R1 = PHOKOS rock phosphate + rice straw + poultry manure, R2 = TRIPHOS rock phosphate + rice straw + poultry manure +
Trichoderma harzianum
, R3 = ASPHOS rock phosphate + rice straw + poultry manure + Aspergillus niger with dosage of 7.5 tha. The result
showed that application of compost enriched with rock phosphate and microorganisms R1, R2 and R3 were significantly increase the growth of
Setaria splendida
Stapf in terms of plant height, shoot and root dry weight compared to R0, but it was not significantly affect phosphorous content in
shoot, root and soils. Composite analyses for phosphate solubilizing fungi PSF in soils showed that there was PSF in R0, R1 and R2 but not in R3.
It could be concluded that application of compost enriched only with rock phosphate and microorganisms resulted a better growth and P content of
Setaria splendida
Stapf rather than rock phosphate.

1. Introduction
Setaria splendida Stapf is one of potential fodder plants which had well
adaptation, productivity and quality. This fodder plant could stand in unfertile soils, but very responsive with fertilization especially with
nitrogen and phosphorous and sometime with potassium [1]. Cultivating this fodder plant in poor soils such as ultisol podzolic can be manipulated
with fertilization. Nutrient sources and availability from fertilizer is one of the important factors which affect fodder plant growth and production.
