Abstract Two field experiments were carried out at the experimental Station Farm of Kalabsho and Zayian district, Faculty of Agriculture, Mansoura University, Egypt, during the two successive winter seasons of 2013/2014 and 2014/2015. The objectives of this research was to aimed study the effect of foliar application with humic acid, amino acids under nitrogen fertilizer levels on the growth, physiological, yield components, yield and chemical characters of three bread wheat cultivars grown in newly reclaimed sandy saline soil conditions. It could be noticed that there were significant differences in most of growth, physiological, yield components, yield and chemical characters on studied wheat cultivars foliar spraying and nitrogen fertilizer in both seasons. Experiments were arranged in a strip-split plot design with three replications. Studied wheat cultivars i.e. Shaka 93, Gemiza 9 and Giza 168 were assigned in the main plots. foliar spraying treatments i.e. spraying with water, spraying with humic acid in the form of Actosol at rate of 5 ml Actosol/liter water in each spraying, spraying with amino acids in the form of Amino-Cat at rate of 5 ml Amino-Cat/liter water in each spraying and Spraying with mixture of Actosol and Amino-Cat at rate of 5 + 5 ml/liter water, respectively in each spraying in sub plots. Application of nitrogen fertilizer levels i.e.166, 214 and 262 kg N/ha in sub-sub plots. It could be noticed that there were significant differences in most of growth, physiological and chemical characters on studied wheat cultivars, foliar spraying and nitrogen fertilization in both seasons. Conclusion:- It could be stated that foliar spraying of Giza 168 cultivar with mixture of humic and foliar spraying mixture of Actosol and Amino-Cat at the rates of 5 + 5 ml /liter water beside increasing fertilizing rate up to 262 kg N/ha and produced the best grain yield and straw yield characteristics under newly reclaimed sandy saline soil of North Nile Delta, Egypt. |
