The study assessed the impact of continuous application of vermicompost
and chemical fertilizers nitrogen, phosphorus and potassium (NPK) on
arecanut in India. Key parameters examined were biomass production,
nutrient uptake, yield, soil fertility and net benefit. Pooled analysis of 8-year
data revealed that nutrient application registered significantly higher yield
(2585–3331 kg ha¡1) than no nutrition (1827 kg ha¡1). Yields in organic
nutrition were around 85% of the yields obtained in inorganic NPK. The
concentrations of leaf N and K were significantly higher with NPK than with
vermicompost. Vermicompost significantly increased soil organic carbon and
the availability of calcium (Ca), magnesium (Mg), manganese (Mn) and
copper (Cu), but reduced exchangeable K in soil. The total uptake of K and Ca
together contributed positively to 75% variability in total biomass
production. Nutrient removal of iron (Fe), P, K and Cu positively influenced
the yield with about 81% variability. Biomass partitioning and nutrient
uptake pattern are important for fertilization program of arecanut.
