| Abstract | ||||
| This study investigated the effect of foliar application of zinc (0, 75, and 150 ppm/L) and yeast extract (0, 25, and 50 ml/L) on the yield, yield components and seed quality of lupin. Two experiments were conducted at the Agricultural Experimental Farm of Al- Azhar University, Assiut Governorate, during the 2022/2023 and 2023/2024 growing seasons. A randomized complete block design (RCBD) with split-plot arrangement and three replicates was used, with zinc levels assigned to the main plots and yeast extract levels to the sub -plots. Results demonstrated that increasing zinc concentration up to 150 ppm significantly improved all measured traits in both seasons. Similarly, increasing yeast extract concentration to 50 ml/L consistently enhanced yield, yield attributes, and seed protein content. It was concluded that foliar spraying with 150 ppm zinc and combined with 50 ml/L yeast extract provided the best results in terms of productivity and seed quality under the given experimental coditions. | ||||
