Abstract

In a field experiment, the effect of rate and time of foliar urea application on protein content and QUALITY in two cultivars of winter WHEAT, 'Falat' and 'Marvdasht', was studied. A split-plot arrangement of treatments in a randomized complete block design was used with cultivars as the main plots and factorial levels of five urea foliar application rates (0, 8, 16, 24and 32 kg N ha-I) and three stages of application (booting, anthesis and early-milk), as sub-plots. The results showed that each 8 kg ha-1 increment in N applied as urea was associated with a 0.6% increase in grain protein in both cultivars. Both grain yield and protein percentage were increased resulting in higher protein yield. Several measured protein QUALITY criteria (farinograph water absorption, wet gluten and sodium dodecyl sulphate (SDS)-sedimentation) were improved by foliar N application. Farinograph absorption was positively, but not strongly, correlated to the grain protein in both cultivars. Wet gluten and SDS sedimentation volume were not related to the grain protein of either cultivar. These results suggested that FOLIAR N FEEDING at appropriate time and rate could be employed, with no leaf damage or risk of lodging, to enhance both grain protein and its QUALITY.
