PERTUMBUHAN BAYAM KUNING (AMARANTHUS BLITUM) DENGAN PEMBERIAN PUPUK ORGANIK CAIR TUMBUHAN PAKU ACROSTICHUM AUREUM, NEPHROLEPIS BISERRATA, DAN STENOCHLAENA PALUSTRIS
ABSTRACT: The amaranth
(Amaranthus blitum) is a type of commonly cultivated spinach. The use of
inorganic fertilizer for growing spinach needs to be reduced by using
organicfertilizer for sustainable culture. The plant species which are abundant
and potential to be used as the material for organic fertilizer are the fern
weeds. The purpose of this research to determine the content of nutrient of the
Organic Liquid Fertilizer (LOF) from ferns Acrosticum aureum, Nephrolepis
biserrata, and Stenochaena palustris, as well as its effects on the growth of
the amaranth. This research used a Completely Randomized Design (CRD) with 6
degrees of treatment. The analysis showed the value of As <0.010, Hg
<0.004, Pb <0.040, Cd <0.020, Sn 0.010, C-Org 0.29 %, N 0.04 %, P
0.008 %, K 0.1%, Fe 18.09 ppm, Mn 6.98 ppm, Cu 0.53 ppm, Ca 49.34 ppm, Mg 169
ppm, S 28.03 ppm, and Zn 1.24 ppm. The ANOVA results showed that the LOF from
ferns had significant effect on the plant height (F5.24 = 2.934, p = 0.033),
number of leaves (F5.24 = 4.797, p = 0.04), number of lateral buds (F5.24 =
10.585, p = 0.0001), leaf breadth (F5.24 = 3.695, p = 0.013), and weight of wet
root (F5.24 = 4.109, p = 0.008). The concentration of 75 ml/L had the highest
effect on the parameters of the plant height and number of leaves. The
concentration of 60 ml/L had the highest effect on the parameters of lateral
buds and weight of wet roots. The concentration of 15 ml/L had the highest
effect on the parameter of leaf breadth.
