Mixed Ammonium and Nitrate Nutrition of Wheat Under Different Soil Salinity Regimes
M. Arshad, M. Sharif Zia and Tahira Ahmad

Abstract: Effect of varying NH4+ -N: NO3-N ratios on wheat yield and N utilization on artificially salinized soil with salinity regimes of 0, 6 and 12 dS m–1 under pot culture conditions revealed that productive tillers, grain, straw and total biomass were the highest with NH4+ -N: NO3-N ratio of 50:50. These growth parameters were the lowest where either NH4+ -N or NO3-N was used alone. Similarly N uptake and N recovery in wheat was significantly higher at optimum NH4+ -N: NO3-N ratio of 50:50 than where NH4+ -N or NO3-N alone was used. Increasing salinity levels significantly reduced the wheat yield and N utilization. However, balanced N nutrition was helpful to ameliorate the harmful affect of salinity to some extent.
