| Abstract | ||||
| In order to investigate response of some yellow maize hybrids (single cross Gold-21, single cross 168 and single cross Kahraman) growth and grains quality for spraying with anti-stress substances (without, spraying with irrigation water, salicylic acid, potassium silicate and proline acid) under different sowing dates (16th May, 1st June and 15th June) to face climatic changes, two field experiments were conducted at the private field in El-Orman Village, El-Sinbelaween district, Dakahlia Governorate, during the 2023 and 2024 seasons. Every planting date was carried out in a different experiment. Three replications of each sowing date experiment were conducted using a strip-plot design. Early sowing of maize on 16th May produced the highest growth and grains quality traits. Single cross Gold-21 was superior than two other yellow maize hybrids and resulted in the highest growth and grains quality traits. The highest growth and grains quality traits were recorded when spraying maize plants with salicylic acid at 5 g/L in each season. Based on the findings of the research and in light of the climate changes that the whole world is witnessing, as well as Egypt, it could be concluded that early sowing yellow hybrid single cross Gold-21 (SC Gold-21) on 16th May and spraying with salicylic acid at 5 g/L to maximizing grain quality and growth in the El-Sinbelaween district of the Dakahlia Governorate, Egypt’s environmental conditions and similar areas. | ||||
