| Abstract | ||
| During the two successive seasons of 2018/2019 and 2019/2020 the feild experiment was conducted in Al-Aqwaz, Giza Governorate, aiming to study the effect of three planting dates (1st of December, 15th of December and 1st of January) and three irrigation regimes (50, 75 and 100% of the irrigation requirements for each of the selected planting date) on the vegetative growth, chlorophyll, tuber chemical composition (nitrogen, potassium, phosphorus and calcium), tuber yield and its quality parameters (specific gravity, dry matter, protein and starch). The results showed that there were significant effects for the treatments of planting dates and irrigation regimes on all of the studied characters, in both seasons of study. Also, the effect of irrigation regems was more pronounced comparing with the effect of plantting dates on studied characters. However, The planting on the first of December and/or the irrigation with 100% of the irrigation water requirements were the most satisfactory treatments for exhibiting the most favorable vegetative growth, highest yield as well as tuber quality for potato cv. Spunta planted in Al-Aqwaz, Giza Governorate or any other similar areas. | ||
