Abstract: A field experiment was carried out during two consecutive rabi seasons of 2009-10 and 2010-11 at the Agronomy farm, College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Bikaner to find out the effect of phosphorus, zinc and iron on growth attributes and yield attributes of wheat (Triticum aestivum L.) in Loamy sand soils of Western Rajasthan with ten treatments comprising 4 levels of phosphorus (0, 20, 40 and 60 kg ha-1) and zinc (0, 3 and 6 kg ha-1) in main plots and 3 levels of iron (0, 3 and 6 kg ha-1) in split-plot design with three replications. Application of phosphorus up to 40 kg P2O5 ha-1 significantly increased the dry matter production, CGR and RGR of wheat over control at 30, 60, 90 DAS and at harvest in pooled analysis. Yield attributes viz. effective tillers plant-1 and number of grains ear-1 were also significantly enhanced with the increasing level of phosphorus up to 40 kg P205 ha-1 in pooled analysis. Application of phosphorus up to 40 kg P2O5 ha-1 significant]y increased the grain, straw and biological yields beyond which it increased non-significantly and registered a mean increase of 26.2, 30.6 and 28.8 per cent, respectively over control.
