the table indicated that wheat intercropping systems can add 266.8 thousand
hectares of wheat, which produced 1689.3 million ton of wheat seeds. The total
wheat production under application of deficit irrigation on raised beds and intercropping systems will reach 13,583.7 million tons, which will reduce wheat
production- consumption gap to 5837.6 million tons, in which self-sufficiency ratio
will increase to reach 70%.
Table 6.11 also indicated that more governorates can attain self-sufficiency in
addition to surplus in wheat production. These governorates are Behira, Kafr
El-Sheik and Sharkia in Lower Egypt, Fayoum in Middle Egypt, and Assuit and
New Valley in Upper Egypt.
6.3.4 Saved Irrigation Water from Other Winter Crops
and Wheat Self-Sufficiency
An amount of irrigation water was saved from cultivation on raised beds and application of deficit irrigation to Egyptian clover and sugar beet in Chap. 3 and to onion
and winter tomato in Chap. 4. Because these four crops have surplus in their
production, we assumed that these amounts of water could be used in cultivating
more lands with wheat to increase its total production and reduce its productionconsumption gap.
Table 6.12 indicated that the highest amount of saved irrigation water will be
obtained from Egyptian clover as a result of its high cultivated area, namely 1472.2
billion cubic meters. The amount of irrigation water saved to sugar beet is ranked
second, namely 491.1 million cubic meters. Whereas, lower amounts of irrigation
water will be saved from onion and winter tomato, namely 129.8 and 57.1 million
cubic meters, respectively. A total of 2150.1 billion cubic meters could be saved
from these four crops.
6.4 Wheat Production-Consumption Gap Using Saved Water
from Other Winter Crops
Table 6.13 showed that using the total saved water resulted from the four studied
winter crops could result in cultivating 273.8 thousand hectares and produce 2861
million tons of wheat seeds. Under application of deficit irrigation to wheat on
raised beds, wheat intercropping systems and the saved water resulted from the four
studied winter crops, the total wheat production will reach 16,444 million tons,
which will reduce the gap to reach 2977 million tons, in which self-sufficiency ratio
will reach 85%.
6 Wheat Insufficiency and Deficit Irrigation
the table indicated that wheat intercropping systems can add 266.8 thousand
hectares of wheat, which produced 1689.3 million ton of wheat seeds. The total

production- consumption gap to 5837.6 million tons, in which self-sufficiency ratio
