Abstract:
The objective of this study was to know the effect of biofertilizer and humic acid on NPK
content and yield of riceIR-64 cultivar in Indramayu. Biofertilizer containing nitrogen fixing
microbes (Azotobacter and Azospirillum) and phosphate solubilizing microbes (Pseudomonas
mallei, Pseudomonas cepaceae, Penicillium sp. And Aspergillusniger) was used in this
experiment. This research was conducted from April to July 2017 in paddy fields located at
Gantar District, Indramayu. A Randomized Block Design (RBD) was used in this experiment
with seven treatments and repeated four times. The treatments were biofertilizer(50 kg ha-1) and
humic acid (20 L ha-1) with different recommendation doses of NPK fertilizer (0%, 25%, 50%,
75% and 100%). The result showed that biofertilizer and humic acid with different
recommendation doses of NPK fertilizer significantly increase P content (0,73%) and yield of
rice (8,93 t ha 1). |
