Abstract

The study was conducted to determine the effects of dosage and frequency of applying single fertilizers (N,P, K) and compound NPK fertilizers on total nitrogen (N-total) using lowland rice (Oryza sativa L.) grownin Inceptisols. The research was carried out in rice fields located in Ciparay, Jelekong Subdistrict, BaleendahDistrict, Bandung Regency. A Randomized Complete Block Design (RCBD) was employed, consisting of seventreatments with three replications: (1) Control, (2) Single NPK fertilizer (grade 123,75-36-50), Frequency3, (3) Compound NPK Pelangi fertilizer (grade 80-40-40), Frequency 3, (4) Single NPK fertilizer (grade 8040-40),Frequency 3, (5) Single NPK fertilizer (grade 123,75-36-50), Frequency 2, (6) Compound NPKPelangi fertilizer (grade 80-40-40), Frequency 2, and (7) Single NPK fertilizer (grade 80-40-40), Frequency2. The results indicated that, in general, fertilization applied twice yielded the highest N-total values.Meanwhile, fertilization applied three times resulted in higher available phosphorus (P-available) levels.However, differences in fertilization treatments did not significantly affect exchangeable potassium (K) inInceptisols.
