Abstract


Palm oil is one of the major and prime agricultural commodities in Indonesia. Better palm oil
seedling growth depend on nutrient and organic matter availability that can be fullfilled by using
palm oil mill effluent (POME) and NPKMg (15:15:6:4) fertilizer. The objectives of the research
were to study growth response of palm oil pre nursery seedling to aplication of POME and NPKMg
(15:15:6:4) fertilizer.  The research was held at  screen house of Agricultural Faculty USU            (±
25 m asl) in April to July 2014 using a factorial randomized block design with two factors and three
replications. The first factor were POME (0; 1.5; 3.0; 4.5 l/seedling) and the second factor were
NPKMg (15: 15: 6: 4) fertilizer (0; 2.5; 5.0; 7.5 g/seedling). Data were analyzed with ANOVA and
continued with Duncan multiple range test. The Parameters observed were plant height,      stem
diameter, leaves number, total leaf area, leaves greenness, fresh and dry root and upper part weight.
The results obtain were the effect of POME until dose L
(3.0 l/seedling) were increase for all
parameters except leaves greenness, fresh and dry root. The effect of  NPKMg (15:15:6:4)  fertilizer
until dose P
2
2
(5.0 g/seedling) increase for all parameters except stem diameter. The interaction of
these two factors until L
3
P
were increase leaves number, leaves greenness, fresh root weight, fresh
and dry upper part weight.

Keywords:  palm oil mill effluent, NPKMg (15:15:6:4) fertilizer, palm oil seedling
