| Abstract | ||||
| A field experiment was carried out at the Experimental Farm of Agronomy Dept., Assiut University, during the 2021/2022 and 2022/2023 seasons. The work aimed to investigate the effect of three phosphate fertilizer applied dates (before the first P1, second P2, and third irrigation P3) and four gibberellic acid levels (0, 50 G1, 150 G2, and 250 G3 ppm) on three fab bean cultivars (Misr1, Sakha 4 and Giza 843). The experiment was laid out in randomized complete block design (RCBD) using a strip plot within a split plot with three replicates. The plot area was 9 m2. The results revealed that maximum seed yield in addition to yield attributes were produced from plants receiving 250 or 150ppm gibberellic acid with third and second phosphorus application in both seasons. Giza 843 cultivar was significantly higher seed index, biological and seed yield in both seasons. The maximum Pod number/plant and seeds number/pod in the 1st season were recorded by 250ppm gibberellic acid concentration under the first and second phosphorus application dates (G3×P1 and G3×P 2) in the 2nd season. Moreover, the maximum seeds and biological yield were recorded by 250ppm gibberellic acid concentration under the third phosphorus application date (G3×P3) in both seasons. Furthermore, the tallest plants, maximum seed index and biological yield were recorded by Giza 843 cultivar under the second and third phosphorus application dates (V3×P2 and V3×P3) in both seasons. Maximum pod number/plant and seed yield were recorded by Misr1 cultivar under the first and third phosphorus application dates (V1×P1 and V1×P3) in both seasons. | ||||
