What is Organic Fertilizers in Shallot Farming?

Organic fertilizers in shallot farming refers to the application of manure, compost, bokashi, vermicompost, and biofertilizers to enhance bulb yield, soil fertility, and microbial diversity in Allium ascalonicum cultivation.

Studies test bokashi composting with NPK on dry land (Sri Anjar Lasmini et al., 2018, 52 citations) and liquid eco-enzyme fertilizers for growth (Novianto, 2022, 13 citations). Biochar and compost improve nutrient uptake under saline conditions (Rahayu et al., 2019, 9 citations). Vermicompost combined with sheep urine boosts production (Mariana Putri et al., 2013, 8 citations). Over 20 papers span 2013-2022.

Key Challenges

Why It Matters

Organic fertilizers sustain shallot yields on degraded soils, as bokashi plus NPK increased production on dry land (Sri Anjar Lasmini et al., 2018). They reduce chemical dependency in regions like Banten, where combined organic-inorganic use raised bulb yields (Resmayeti Purba, 2016). Eco-enzymes from household waste support eco-friendly farming, enhancing productivity without synthetic inputs (Novianto, 2022). These practices improve soil health amid declining fertilizer efficacy in Indonesia's shallot belts.

Key Research Challenges

Optimal Dosage Rates

Determining precise application rates of organic fertilizers like bokashi or vermicompost remains inconsistent across soil types. Sri Anjar Lasmini et al. (2018) tested combinations with NPK but lacked universal ratios. Field trials show variability in bulb size and yield (Mariana Putri et al., 2013).

Integration with Chemicals

Balancing organic inputs like compost with NPK to avoid nutrient imbalances challenges farmers. Resmayeti Purba (2016) found combined use effective in Banten but noted timing issues. Rahayu et al. (2019) highlighted synergies under salinity yet suboptimal standalone performance.

Soil-Specific Efficacy

Organic fertilizers perform variably on dry land, sandy, or highland soils. Sri Anjar Lasmini et al. (2018) succeeded on dry land with bokashi, while highland trials needed adjustments (Atman et al., 2021). Microbial responses differ, complicating predictions (Novianto, 2022).
