Kadar N Dan P Serta Pertumbuhan Vegetatif Padi Gogo (Oryza Sativa L.) Pada Tanah Ultisol Yang Diaplikasikan Pupuk Organik Cair Limbah Ikan Dan Rock Phosphate

ABSTRACT
Rice cultivated on ultisol have several problems such as nutrient content
(such as N, P, K, Ca, and Mg), pH, organic matter, alkaline saturation and cation
exchange capacity are low while exchangeable Al and Al saturation are high.
Efforts to overcome these problems can be carried out by the application of fish
waste liquid organic fertilizer (FWLOF) and rock phosphate (RP). This study
aims to determine the main effect of aplication FWLOF and RP and their
interaction on N and P uptake and upland rice growth on ultisol soil. The research
was conducted at the Green House of the Faculty of Agriculture, University of
Riau, Pekanbaru from January to March 2019. The research in form factorial
experiment 4×3 was arranged in a completely randomized design, 3 replications.
The first factor was fish waste liquid organic fertilizer consist of 4 levels (0,
30.000, 60.000, and 90.000 liter.ha-1). The second factor was rock phosphate
consist of 3 levels (0, 50, 100 kg P2O5 ha-1). The results showed that the
application of FWLOF dose of 60.000 liter.ha-1 increased uptake of N and P and
the growth of upland rice, namely plant height, number of tillers and dry weight
compared to other doses, while the application of RP dose 50 kg P2O5 ha-1
increased absorption efficiency of P, uptake of N and P and growth of upland rice,
namely the number of tillers and dry weight compared to other doses.Interaction
of aplication FWLOF dose 60.000 liter.ha-1 increased absorption efficiency of P,
uptake of N and P, number of tillers and dry weight.
Keywords: upland rice, ultisol, liquid organic fertilizer of fish waste, rock
phoshate
