Abstract

The decline in lowland rice production can be caused by nitrogen nutrient loss through volatilization. The application of humic acid and Phonska 15-15-15 fertilizer can be a solution. This study aimed to determine the effect of humic acid and Phonska 15-15-15 fertilizer on nitrogen uptake by rice plant, rice plant growth, and nitrogen residues in paddy soils. The research used a randomized block design with 8 treatments and 3 replications. The treatments in this study included K (Control), A (Humic Acid 5 kg ha^-1), P (Phonska fertilizer 240 kg ha^-1), A1 (Humic Acid 1 kg ha^-1 + Phonska 240 kg ha^-1), A2 (Humic Acid 2 kg ha^-1 + Phonska 240 kg ha^-1), A3 (Humic Acid 3 kg ha^-1 + Phonska 240 kg ha^-1), A4 (Humic Acid 4 kg ha^-1 + Phonska 240 kg ha^-1), and A5 (Humic Acid 5 kg ha^-1 + Phonska 240 kg ha^-1). Â The parameters observed included nitrogen uptake in rice plants, rice plant growth, and nutrient residues in the soil. The results showed that humic acid and Phonska 15-15-15 fertilizer significantly affected N nutrient uptake, the highest effect was found in A3, which was 1.03 g plant^-1 in 4 MST and 1.77 g plant^-1in 6 MST. Humic acid and NPK Phonska 15-15-15 fertilizer yielded the highest plant height at 4 MST and 6 MST was A3 treatment. The number of tillers at the age of 4 MST treatments gave the highest results, namely in the treatment of A3 and A4 as many as 3.33 tillers. At the age of 6 MST the treatment that gave the highest results was A3 treatment with 8 puppies. The nitrogen residues in the soil showed a significant effect where the highest residual yield in the soil was obtained from the A3 treatment of 0.23% as well as pH and C-organic respectively 6.69 and 3.10%.
