Implication

Field experiments reveal enhanced maize yields and improved soil quality through integrated amendments in acidic soils.

Key Points

  • This research aims to evaluate the effects of lime, vermicompost, and phosphorus fertilizer on maize productivity and soil quality in acidic soils.
  • Conducted field experiments in 2023/24 and 2024/25 cropping seasons
  • Employed a randomized complete block design
  • Applied factorial combinations of lime, coffee husk vermicompost, and phosphorus fertilizer rates
  • Collected soil samples before planting and after harvest to assess soil changes
  • Recorded agronomic data for maize yield and yield components.
  • Soil pH improved significantly, with Cambisols rising to 5.95 and Nitisols to 5.99
  • Exchangeable acidity decreased notably, improving soil chemical properties
  • Available phosphorus increased significantly in both soil types
  • Maize yield increased substantially, peaking at 9.15 t/ha in Cambisols and 7.03 t/ha in Nitisols
  • Economic analysis showed profitability of integrated amendment application.
