Abstract:

The field experiment was conducted at College of Agriculture, Shivamogga during kharif 2015-2016. The total quantity of P and plant-available P often differ greatly fraction in acidic soils. Assessing available P is fundamental aspect to managing P in many of these soils. The objectives of this study were to effect of phosphorus levels through integrated nutrient management (INM) packages on status of phosphorus in soil under groundnut crop. The results revealed that significantly higher availability of phosphorus was recorded in treatment (T9) whereas, lower phosphorus availability was found in treatment (T1) at different stages of the crop growth stages. Significantly higher amount of all inorganic and organic forms of P in soil were recorded in application of higher dose of P i.e.50 kg ha-1 (T6). The percent contribution of different phosphorus fractions viz., Saloid-P Al-P, Fe-P, Reductant Soluble-P, Occluded-P, Ca-P, Organic-P to Total-P, the lowest contribution to total-P from Occl-P (3.20 %), Ca-P (3.46 %), followed by Saloid-P (6.16 %), Red-P (9.83 %). The contribution from org-P (51.96 %) to total-P found to be highest, but Al-P (13.73 %) and Fe-P (13.16 %) was observed to be similar per cent contribution to total-P.
