On-farm trials in India investigated the role of nutrient imbalance on yellow
leaf disease (YLD) in arecanut on a laterite soil using compositional nutrient
diagnosis (CND) approach. Soil fertility status was imbalanced with high
organic carbon status and low phosphorus (P) and potassium (K). The CND
norms indicated that the order of nutrient demand was changed with
nutrient application. Interventions increased yield by 50% during 2007–
2010. The correlations indicated positive effect of nitrogen (N) and K and
negative effect of manganese (Mn) on yield. The CND indices for NPK were
important discriminators between yellowed and apparently healthy populations
both in 2007 and 2010. Linear regressions between leaf nutrient
concentrations and CND indices were significant for P, K, iron (Fe), Mn, and
copper (Cu) (R2 = 0.44–0.53). Results suggest that the predisposing factor
for YLD might be nutrient imbalance in the soil leading to deficit of major
nutrients in plant.
