Optimum Application Rate of Nitrogen, Phosphorus, and Potassium Fertilizers for Kenaf (Hibiscus cannabinus L.) Yield and Soil Chemical Properties in a Reclaimed Paddy Soil: A Pot Experiment

Kenaf (Hibiscus cannabinus L.) has been considered one of the alternative crops for bioenergy production, potentially replacing fossil fuel. However, there are few studies available on systematically investigating kenaf growth characteristics and its fertilization conditions so far. Our study investigated biomass productivity soil properties at different regimes including three major treatments (N, P2O5, K2O) with four application levels [0%-50%-100% (as recommended), 200%] in a reclaimed paddy during pot experiment under upland condition 2021. The results showed maximum was observed when 158 kg ha-1 N, 156 P2O5 102 K2O were applied, showing 62.6 g d.w pot-1, 64.1 64.9 respectively. revealed that mainly positive correlations electrical conductivity (EC) total N contents soils, suggesting these could be limiting factors production. provides better understanding producing biomass, filling gap promising nutrient management strategy optimum production southern soils.The effect inorganic experiment.
