Influence of Nitrogenous Fertilizers, Gypsum and Seed Priming on Wheat Yield under Salt Affected Soil Conditions

Abstract: Field experiment, to evaluate the effect of nitrogenous fertilizers i.e. urea, ammonium nitrate and ammonium sulfate with and without gypsum and seed priming on productivity of wheat, was performed.The field was surveyed by EM-38 at 2x2m grid to identify areas of uniform salinity. The experimental design was factorial randomized, having ECe values of 3.5 to 5.5, 4.0 to 6.9, 5.0 to 9.1 and 6.1 to 10.1 dSm-1 in R1, R2, R3 and R4 respectively. There was no significant effect of fertilizer type, gypsum and seed priming on any yield parameters. However, ammonium nitrate was better over the other two fertilizers in terms of yield. Similar to yield, soil and plant K+, Na+ concentrations and K/Na ratio were not affected significantly with various treatments. Leaf K+ and K/Na ratio was positively correlated with grain yield and Na+ concentration was negatively correlated.
