Field experimentations were carried out to examine the impact of N-levels and foliar application treatments on yield characters of sunflower cultivar Sakha-53 during 2016 and 2017 seasons at El-Muhandis Village in Sherbin District, Dakahlia Governorate, Egypt. Experimentations were conducted using a strip plot design with three replicates. Vertical plots were devoted to nitrogen fertilizer rates (20, 25 and 30 kg N/fed). While, six spraying transactions i.e. without, water spraying, amino acids (AA), yeast extract (YE), commercial NPK + micro elements (Fe, Mn and Cu) as Estima-Green powder, and the mix of AA, YE and commercial NPK + micro-elements were distributed on the horizontal plots. Fertilizing with 30 kg N/fed yielded the maximum rates of yield and its attributes during 1^st and 2^nd years. Fertilizing with 25 kg N/fed came after the maximum rate of N fertilizer. The spraying two times with the mix of AA, YE and commercial NPK + micro-elements gave the maximum rates of crop and its components in both years, then spraying sunflower plants twice with commercial NPK + Micro (1.5 g/L) in every spray. It can be accomplished that sunflower cultivar Sakha-53 with 25 kg N fed^-1 as well as spraying twice with the mix of AA, yeast extract and commercial NPK + Micro so as  to preserve high productivity at the same time decrease production expenses and ecological contamination under the ecological circumstances of Dakahlia- Governorate, Egypt.
