Effect of phosphorus, manganese and iron on yield and nutrients uptake by wheat (Triticum avestivum L.) in inceptisols

摘要

To evaluate the effect of P, Mn and Fe on uptake of macronutrients at different growth stages; of wheat Afield experiment was conducted to find out the effect of phosphorus, manganese and iron on growth parameters, yield attributes and yield of wheat{Tritlcum aestivum L.) in inceptisols during the rabi season of 20-1-02 and 2002-03. Treatments comprised combinations of two levels of phosphorus (0 & 20 kg P ha1) were taken in a clay loam soil with pH 7.7, organic carbon (0.53%), electric conductivity(0.91 dSnrr1), medium in available nitrogen (263.71 kg ha~(-1)), medium available phosphorus (16.12 kg ha~(-1)) and high in available potassium (661.75 kg ha~(-1)). Results revealed that significant increased yield and nutrients uptake at 30,60 DAS andgrain and straw by wheat with the increasing levels of phosphorus, manganese and iron.
