ABSTRACT
The aims of this study were to determine the dose of inorganic
fertilizer of NPK combined with organic fertilizer from CM (Cow Manure) to grow
paddy Inpara 8 variety planted in a tidal soil. This experiment was done in a green house and conducted from July to December
2020. This pot experiment used factorial completely randomized design with two
factors and three replications. The first factor was NPK which consisted of two
kinds of NPK fertilizers which were urea 200 kg/ha, SP-36 100 kg/ha, KCl 100
kg/ha from recommended fertilization and urea 37 kg/ha, SP-36 56 kg/ha, KCl 183
kg/ha from calculation of the specific location soil analysis (in situ data).
The second factor was dosage of CM at 5, 7.5 and 10 tons/ha respectively. The results showed that
NPK fertilization from specific location combined with CM at 10 tons/ha was the
best treatment for rice production in an infertile tidal swampland producing 2.20 tons/ha.
