| Abstract | ||
| Calcareous soil surface crusts, subsoil layers cementation, low organic content, and nutrient availability are crucial difficulties restrict their handling and yield. The objective of this study is to indicate the effect of magnetic treatment (MT) of barley seeds before sowing when fertilized by the foliar-sprayed chitosan (CHS) with and without the K-humate (K-H) on the crop yield and quality in calcareous soil. Field experiments were carried out during the 2022/2023 - 2023/2024 winter seasons at El-Nubaryia Agricultural Research Station in a split-plot design in triplicate. The main factor was the MT of barley seeds. The sub-main factor was the CHS three application rates: CHS1, CHS2, and CHS3 using 10, 20, and 40 mL, respectively, from the stock solution per 1 L water with and without the K-H (10 kg ha-1). Results have indicated that the CHS3+K-H treatment has significantly increased the soil available N by 100.8% relative to the corresponding C and by 50.2% relative to the same treatment without MT. The CHS3+K-H treatment without MT of seeds has produced the most significant increase for the biological and grain yield (Mg ha-1) relative to the C by 75.5% and 53.7%, respectively. The absorbed Si, Zn, and Mn (mg kg-1) was increased but the Fe was decreased compared to the C. It is recommended to activate the barley seeds before sowing by the MT with repeated fertilization by CHS/K-H to enhance the nutrient absorption, growth parameters, and effectively improve the calcareous soil productivity of barley. | ||
