Abstract To study the effect of foliar applications, N-levels and their interaction on growth, yield and its attributes and grain quality of barley Giza 123 cultivar, a field experiments was carried out at the Experimental Farm of Sahl El-Husseiniya,Agriculture Research Station, as a new reclaimed soils (salinity affected soils), during 2015/2016 and 2016/2017 seasons using design of strip-plot with 4 replicates. The vertical plots were assigned to five foliar applications i.e. without, spraying with; Macro + Micro, amino acids, humic acid and the mixture of Macro + Micro, amino acids and humic acid. Horizontal plots billed to 3 levels of N-fertilizer (40, 60 and 80 kg N/fed). Spraying barley plants with the mixture of (Macro + Micro), amino acids and humic acid at the rates of 2 g + 1 ml + 1.25 ml/liter water, respectively in each spraying was the best treatment to increase barley growth, productivity and grains quality, which produced the highest values of these characters, with exception of total carbohydrates % in grains, which had inverse trend into both seasons. Fertilizing barley plants with 80 kg N per fed gave the highest mean values of barley growth, productivity and grains quality, except total carbohydrates % in grains in both seasons. Foliar spraying barley Giza 123 cultivar with Macro + Micro, amino acids and humic acid at the side of fertilizing by 60 kg N per fed in order to maintain high productivity and grains quality at the same time reduce production costs and environmental pollution under the environmental conditions of salinity affected soils. |
