Effect of phosphorus, sulphur and zinc on growth, yield and nutrient uptake of wheat (Triticum aestivum)

A field experiment was conducted during the winter (rabi) season of 1999-2000 and 2000-2001 at Jobner, to study the effect of phosphorus, sulphur and zinc on wheat (Triticum aestivum L. emend. Fiori & Paol.). Pooled analysis revealed that the growth parameters, yield attributes, yield, net return and benefit : cost ratio increased significantly with application of 40 kg P2O5, 40 kg S and 5 kg Zn/ha. In general, nutrient uptake increased up to highest level of P, S and Zn, except that P uptake was reduced at highest level of zinc and Zn uptake was reduced at highest level of phosphorus.
