| Abstract | ||||
| This study aims to investigate the effect of spraying with different levels of amino acids (0, 3 and 6 ml/L) and fertilization with organic fertilizer (control, 6 and 9 ton/feddan) (feddan = 4200 m² = 0.420 hectares = 1.037 acres) on soybean. Where two field experiments were planted at the Agricultural Research Center of the Faculty of Agriculture, Al-Azhar University (Assiut Branch), Egypt, during the summer seasons of 2021 and 2022 on soybean variety Giza-111. A split plot design with three replicates were used; where the rates of farmyard manure were distributed on the main plot, while spraying with amino acids was distributed randomly in the subplot. The obtained results showed that the addition of organic fertilizer with increasing rates (control and 6 and 9 ton/feddan) led to a significant increase in the yield, its components and the percentage of oil and protein in the seeds, in both seasons. The obtained results indicated that foliar application with amino acids at a rate of 6 ml/L caused significant increases in all traits under study (plant height, number of branches/plant, number of pods/plant, 100- seeds weight (g), seed yield kg/feddan and oil and protein percentage) as compared with the control and 3ml/L treatments in both seasons. Therefore, this study recommends the addition of farmyard manure at a rate of (9 ton/feddan) and foliar spraying with amino acids at a concentration of (6 ml/L) improved the production and quality of soybean under Assiut governorate conditions, Egypt. | ||||
