Upper Egypt is characterized by high temperatures in summer and low temperatures in winter, which has a significant impact on the dates of planting maize in this region. The productivity of the maize crop as well as the efficiency of the use of water can be severely affected by planting dates and drought. Consequently, the optimum irrigation level and planting date must be determined based on local conditions. Two irrigation schemes were used: (1) control (full irrigation water applied), (2) 70% of irrigation water. Field experiments were conducted at the water studies and research complex station, National Water Research Center in Toshka to evaluate two irrigation levels (full irrigation water applied and 70% of irrigation water requirements) under five planting dates (early seeding (mid-February and March), normal (mid- June) and late planting (mid- August and September) in 2019 and 2020) to determine the optimum planting date and irrigation level. Early SD has increased the days between seeding and plant emergence. Late SD reduced the number of days until the plant matured and had higher grain yields and water use efficiency (WUE). The planting date in September under the irrigation level of 70% achieved the best productivity and the best water use efficiency, where the productivity was 7.01 Mg ha−1 and the water use efficiency was 0.72 kg/m3 The data confirm the general perception of farmers that the September sowing date under 70% irrigation levels is the best within the experimentation area.

“…Soil erosion and denudation are influenced by factors such as depth, texture, elevations, slopes, climate, and vegetation cover, which determine the activeness of external erosion factors. soil erosion, whether by water or air, in limited depth of the soil sector and low density of plant cover, leads to its desertification (Hegazi, A.M. et al (2009).

This study employs the MEDALUS model, developed by the European Union, to estimate the degree of desertification in European Mediterranean countries. The model classifies environmental sensitivity to desertification (ESD) to five degrees based on soil, vegetation cover, and climatic conditions. The study area was carefully selected due to its location in the eastern margin of the Delta of the Nile, overlapping between Nile silt and delta sediments and the sands of the eastern desert. The area encompasses various land uses, including ancient agricultural lands, agricultural reclamation, and vacant lands suitable for future agricultural and urban expansion. The study revealed that 76.4% of the area has an average soil quality index, 23.6% has a low one, and 23.9% has a good vegetation cover index, 29.1% is average quality, and 47% has a low one. The study also revealed that 65.1% of the area has an average climate quality index, while 34.9% has a low one. The study concluded that 2.4% of the area has a very high environmental sensitivity index to desertification, 61.2% is environmentally sensitive, 22.8% of its area is medium sensitive, and 13.6% is low (ESD).

“…length. The various soils along this coastal littoral have been pedologically studied through reconnaissance; semi-detailed and detailed soil surveys during the last 50 Years by the Desert Institute and the Desert Research Center of Egypt and classified according to FAO (2002) and Hegazi et al (2009) and its F IFTEEN soil samples from successive strata were collected for five soil profiles representing assimilated four geomorphology units in the northwestern coast of Egypt. For mineralogical structure, the soil samples were studied microscopically and X-ray diffraction was done.…”
