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 after flowering. 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 protein content increased significantly by foliar application of nitrogen. data showed that there was significant difference among protein content of treatment. according to results, use of 8kg.ha^-1 urea was the best treatment for grain protein increase. in this treatment, seed protein content increased from 11.3 to 12.8 percent. grain yield didn t affect by treatments.
