This work was performed out during the two consecutive winter seasons of 2018/2019 and 2019/2020 in the Research Farm at the Faculty of Agriculture, Al-Azhar Univ., Assiut, Egypt, to study the effect of different rates of phosphorus fertilizers (15.5, 31 and 46.5 Kg. P2O5/fed.) and foliar with amino acids (control, 2 and 4 cm/L) on growth, yield and its components and seed quality of chickpea cv. Giza-195. The experiments were performed in a splitplot design with three replicates; where phosphorus rates were assigned to the main plot while amino acids were distributed randomly in subplot.The obtained results showed that increasing the phosphorus fertilization rates from 15.5, 31 and 46.5 kg P2O5/fed caused a significant increase in all traits under study in both seasons.amino acids foliar increase of application from 0, 2 to 4 cm/L caused significant and gradual increases in all studied characters, i.e. plant height, number of branches and pods/plant, 100-seed weight, seed yield/plant, as well as seed and straw yields/fad. This application also, increased protein percentages in seeds.The study recommended that phosphate fertilization at a rate of 46.5 kg P2O5/fed and spraying with amino acids at a concentration of 4cm/L to obtain the highest yield from the faddan and the highest quality of seeds under Assiut conditions.
