| Abstract | ||
| The present investigation was carried out to study the influence of Nitrogen (N) and potassium (K) fertilizers (soil added at 1&2 kg/tree either solely or combined with one or more of bio-stimulants of Seaweeds extract (SWE), Active dry yeast extract (ADYE) and Humic acid (HA) foliar application beside the N and K fertilization program adopted in the region as control were investigated on growth, and productivity of Canino apricot trees , as well as fruit quality during two successive seasons (2022 & 2023). Data obtained displayed obviously that all twelve investigated nutritional treatments with the N and K mineral fertilization and the three HA, SWE and ADYE bio-stimulants increased significantly all evaluated growth (shoot length, No. of leaves/each, leaf dry weight & area) measurements over control (adopted N and K fertilization in farm during both 2022 & 2023 seasons. Herein T13: (N2K2 + HA + SWE + ADYE) followed both by T12: (N2K2 + SWE + ADYE) and T7: (N1K1 + HA + SWE + ADYE) were the most effective. Moreover fruit quality (both physical & chemical characteristics) of Canino apricot trees followed to great extent the same trend, whereas the most desirable fruit physical (weight, volume & dimensions) and chemical (TSS & TSS/TA ratio) were increased significantly as compared to there of either control or other investigated ones by such three effective treatment. | ||
