Study of wheat grain protein increasing through foliar application of nitrogen after anthesis

An experiment was conducted to study wheat grain protein increasing through foliar application of Nitrogen afterflowering. The RCBD design was analysed with three replications and four N-treatments as foliar application as(N0=0, N1=4kg.ha-1 Urea, N2=8kg.ha-1 Urea, N3=4kg.ha-1 Ammonium Sulfate). Results showed that seed proteincontent increased significantly by foliar application of Nitrogen. Data showed that there was significant differenceamong protein content of treatment. According to results, use of 8kg.ha-1 Urea was the best treatment for grainprotein increase. In this treatment, seed protein content increased from 11.3 to 12.8 percent. Grain yield didn t affectby treatments.
