| dc.description.abstract | An experiment was conducted during 1999-2003 to study the impact of nutrient management through organic matter recycling on yield of component crops in arecanut based cropping system and the nutrient status at Central Plantation Crops Research Institute, Regional Station, Vittal, Karnataka. The experiment was laid out in RBD with four treatments (organic matter recycling (OMR), 1/3"1 of recommended NPK + OMR, 273rd of recommended NPK + OMR and recommended NPK + OMR). The recyclable biomass produced from the system varied between 8.72-10.351 ha1 year. Among the component crops, only the yield of banana was significantly influenced due to nutrient management. Arecanut equivalent yield from the ABCS increased significantly from 1777 kg ha1 in 1999 to 2769 kg ha1 in 2002 indicating improvement in overall productivity of the system per unit area. Significant variability in nutrient status of laterite soils was observed due to ABCS and nutrient management through organic matter recycling. Organic matter recycling maintained sufficient mineral N and available P levels in soil at par with integrated nutrient management treatments. The availability of K increased significantly with integrated use of inorganic fertilizer and OMR compared to only OMR at both soil depths. Significant depletion of available K. in all crop rhizospheres at both soil depths during experimental period revealed the necessity of including K in the fertilizer schedule of the system due to heavy K feeding nature of all the component crops and leaching losses. Comparatively similar yield levels and soil nutrient status noticed with OMR and integrated use of chemical fertilizers and OMR emphasizes the point that the system can be self-sustainable over a long term period. | en_US |
