Abstract

A field experiment was conducted in Karaj to study the effects of a few NITROGEN SOURCEs on WHEAT (Pishtaz var.) yield and quality. Treatments consisted of, T1= Blank (without N fertilizer); T2= Sulfur coated urea (SCU ;(T3=Ammonium nitrate and T4= Urea. The experimental design was a completely randomized block design with three replications. Nitrogen rate was 180 kg N ha-1. WHEAT grain yield increased with application of N fertilizers and the highest grain yield was obtained with T3 and it was significantly different with blank and SCU was significant. Difference between SCU and blank on grain yield was significant but it wasn't significant between Ammonium nitrate and urea. T3 had the highest grain N concentration and it was significantly different to other treatments. Ammonium nitrate had the highest N uptake efficiency (NUE). SCU produced 18.7 kg grain per kg N and in Ammonium Nitrate it was 29.8. Correlation between N uptake and grain yield was positive. Increasing the N uptake enhanced elements uptake. Results showed that in conditions similar to this experiment and with this materials, SCU cannot prepare N to winter WHEAT, in necessary amounts.
