| Abstract | ||||
| The importance of water footprint (WFP) is providing information related to water resource management, especially for countries that have water scarcity and rely on irrigation to enhance food security. A field experiment was conducted during two winter seasons in 2018, and 2019. The current study sought to evaluate the impacts of various nitrogen levels (1.N1: 120, 2.N2: 150, and 3.N3: 180 kg /fed) on potato production as well as the water footprint and water requirement. Vegetative characteristics, yield parameters, N contents, and climate data were measured. The obtained results are clarified that increasing the nitrogen rate up to 180 kg/fed led to increase the vegetative growth characteristics, yield parameters, and water footprint of potato crop. The most significant vegetative growth values were obtained using a 180 kg/fed nitrogen level followed by 150 kg/fed. The greater marketable tuber yield was recorded at 180 kg/fed with 18117 & 17753 Kg/fed values, followed by 150 kg/fed with 16864 and 16545 Kg/fed values for the first and second seasons respectively. The water footprint of potato in Egypt ranges from 237 to 267.8 for nitrogen levels of 120 kg /fed and 180 kg /fed. | ||||
