The influence of nitrogen foliar application on yield and bread making quality parameters of wheat

Abstract

The influence of nitrogen foliar application on yield, protein content, sedimentation value, moist gluten content, parameters of reological dough quality and bread baking quality at the winter wheat cultivar KG-56 were investigated. Two rate of nitrogen (N1-90 kgha-1 N; N2-120 kgha-1 N) were applied. Foliar application of nitrogen in flowering (Ff), milky stage (Fm) and in both flowering and milky stage (Ffm) 12 % solution of urea with 40 kgha-1 N quantity, were conducted. Nitrogen foliar nutrition resulted in increasing grain yield in average for 0.45 tha-1. In average the increasing other investigated parameters were estimated in absolute percents: protein content for 2.5, sedimentation value for 21.0, wet gluten content for 7.2, water absorption for 5.2, farinograph quality number for 25.4, bread weight for 3.0 and bread volume for 37.5 of the absolute percents. Under the influence of foliar N application the B2 quality group was improved to A2 quality group in milky stage. After N foliar application in milky stage (Fm N2), the highest value of analyzed parameters was established, except protein content and bread weight. However, in the case of N foliar application in both stage (flowering and milky stage) protein content and bread weight showed the highest values.
