“…Based on the categorization of the diversity index, it is known that the weed biodiversity at the observation site belongs to the low class (H' < 1.00) and medium class (H' > 3.00). The chemical properties of the soil analyzed in this study included soil reactions (pH), organic-C, total-N, available-P, total-P, total-K, exchangeable bases (Ca, Mg, Na, and K), base saturation, and cation exchange capacity (CEC) [12,13] soil reaction (soil acidity) shows the soil's reaction and affects the soil's ability to provide nutrients for cultivated plants. Most of the soil reactions in the study area are moderately acidic, followed by neutral and acid.…”

The study’s first phase results identified 17 species of weeds with 11 species of low index class and six species of medium index class. Based on nutrient content, there were four locations with low fertility status, SPL1, SPL5, SPL6 and SPL7. In addition, there were three locations, SPL2, SPL3, and SPL4, with moderate fertility levels. In the study’s second phase, the highest pH H2O (6.38) was obtained at a dose of 25 tons per ha of Bokashi weed and 225 kg per ha of SP-36. This treatment was significantly different from other treatments. The highest available phosphorus was detected at a dose of 25 tons per ha of Bokashi weed 225 kg per ha of SP-36, namely 28.87 ppm, which was significantly different from other treatments. Moreover, there was an increase phosphorus uptake in plant due to the application of Bokashi fertilizer and SP-36 fertilizer. P uptake increased at a dose of 25 tones of Bokashi fertilizer per ha (P3) and SP-36 fertilizer dose of 225 kg per ha (S3) with an average of 0.68 g per plant.
