Effectiveness of two prevalent forms of nitrogen -ammonium and nitrate was examined in wheat (Triticum aestivum cv. Sonalika) grown in solution culture. Nitrate fed plants had greater plant height, more leaf number, greater leaf area, higher dry matter production, greater root length and higher moisture per cent in stem and leaf. On the other hand ammonium fed plants were greener due to higher chlorophyll concentration in leaves. Nitrate fed plants had higher content of all essential elements viz. N, P, K, Ca, Mg, Fe and Mn. Ammonium fed plants had higher Mg, Fe and p concentration in leaf which may be correlated with higher chlorophyll concentration. There was a tendency of retention of Fe, Mn and p in roots of nitrate plants. Final harvest data indicated better yield under nitrate form of nitrogen due to larger size of panicle, higher spikelet number, grain number and grain weight.
